The 1992 Pacific hurricane season is the most active Pacific hurricane season on record, featuring 27 named storms. The season also produced the second-highest ACE value on record in the basin, only surpassed by the 2018 season. The 1992 season officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.[1] However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the development of Hurricane Ekeka on January28, and Tropical Storm Hali two months later.
The most notable storm was Hurricane Iniki, which caused billions of dollars of damage to the Hawaiian Islands, primarily in Kauai, along with six fatalities. Hurricanes Lester, Virgil, Winifred, and Orlene also made landfall and killed several people, but were significantly less destructive. Hurricane Darby and Tropical Storm Agatha brought rains and more destruction to Mexico, without making landfall. Hurricane Tina was, in addition to being the strongest storm of the year, the longest-lasting Pacific hurricane at the time.
The Accumulated Cyclone Energy (ACE) index for the 1992 Pacific hurricane season (Eastern Pacific and Central Pacific combined) as calculated by Colorado State University using data from the National Hurricane Center was 294.3units, the second highest value on record for a Northeastern Pacific season.[3] The total represents the sum of the squares of the maximum sustained wind speed (knots) for every (sub)tropical storm's intensity of over 33 knots (38mph; 61km/h), divided by 10,000 while they are above that threshold, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs; calculations are not made for tropical depressions.
Warmer than usual sea surface temperatures due to an El Niño fostered the high level of tropical activity during the year.[4] The season officially started on May 15, 1992, in the eastern Pacific, and on June 1, 1992, in the central Pacific. It ended in both basins on November 30, 1992.
During the season, twenty-seven tropical cyclones formed in the Eastern Pacific (east of longitude 140°W), and twenty-four developed further and became tropical storms. Both of these figures constitute records in the basin, as the 1992 season surpassed the season with the most tropical cyclones (1982, 26) and the season with the most named storms (1985, 22). Of these, fourteen reached hurricane strength and eight became major hurricanes—storms that reach Category3 or higher on the Saffir-Simpson Hurricane Scale.[5]
List of costliest Pacific hurricane seasons (as of 2024)
This season had five storms reach tropical storm intensity or higher in the month of October, the first time on record that this had happened in this basin. In addition, Hurricanes or Tropical Storms Winifred through Zeke are the earliest twenty-first through twenty-fourth named storms in a season in the eastern north Pacific.[6]
The Central Pacific (between 140°W and the International Date Line) saw similarly high levels of activity. Eleven tropical cyclones were tracked by the Central Pacific Hurricane Center throughout the hurricane season. Of those, eight developed in the Eastern Pacific and crossed into the Central Pacific, and three formed within the basin. Two of the storms strengthened to major hurricane status within the Central Pacific's boundaries.[4]
The first storm of the season, Ekeka, formed on January 26, and was the first recorded January central Pacific hurricane. Later in the season, Iniki, crossed into the basin as a tropical depression, strengthened to a Category 4 hurricane, and made landfall in Hawaii, becoming the most destructive hurricane in the state's history.[4]
The first storm of the season developed from an area of disturbed weather near Kiritimati in the Line Islands. The tropical disturbance had been tracked since January 23, and at 0600 UTC January 28, the Central Pacific Hurricane Center designated the system as Tropical Depression One-C. This was unusual, since the system was located well to the south of the area of normal tropical cyclone formation, further south than any other Pacific hurricane at the time, and the formation occurred well outside the climatological bounds of the hurricane season. The system intensified and reached tropical storm status 12 hours later, at which point it became known as Ekeka.[4]
The system continued intensifying until reaching hurricane status at 0000 UTC on January 30, and it reached major hurricane status on February 2, reaching maximum sustained winds of 115mph (185km/h).[7] However, unfavorable wind shear began taking a toll on the storm, causing it to rapidly weaken. Ekeka crossed the International Date Line as a weakened tropical storm, and shortly thereafter degraded to tropical depression status. Ekeka continued westward, passing through the Marshall Islands and later over Chuuk, before dissipating on February 9 about 310mi (500km) off the north coast of Papua New Guinea.[6]
In late March, meteorological conditions similar to what allowed Ekeka to develop persisted in the central Pacific. An area of convection organized into Tropical Depression Two-C, just north of 5˚N, atypically close to the equator, and far to the southwest of Hawaii. Moving west-northwestward, it slowly intensified, intensifying into a tropical storm on March29. Upon doing so, the CPHC gave it the name Hali. Later that day, the storm attained peak winds of 50mph (80km/h), before increased southwesterly wind shear imparted weakening. Hali was downgraded to a tropical depression on March30, and it dissipated shortly thereafter. It never affected land.[4]
On May 26, a tropical wave moved off the Central America, which began to show signs of organization on May 29.[8] Early on June 1, the NHC classified it as a tropical depression while located 460mi (740km) southwest of Acapulco.[8] Based on a combination of ship data and Dvorak intensity estimates, the system was upgraded into Tropical Storm Agatha on June 2.[9] Agatha steered toward the north[8] while steadily intensifying. Around 1800 UTC June 2, the storm peaked in intensity with winds of 70mph (110km/h) and a minimum pressure of 990mbar (990hPa; 29inHg).[6] Maintaining its peak intensity for 30 hours, Agatha gradually decelerated as it passed within 100mi (160km) southwest of the Mexican coast.[8] The center of the storm promptly became less defined on June 3, simultaneously recurving to the west.[10] By 0600 UTC June 5, the storm was downgraded back into tropical depression status prior to dissipating the next day.[8]
Agatha approached close enough to the coast of Mexico that watches and warnings were issued.[8] An estimated 1,500 people were evacuated due to the storms' approach. Waves up to 16ft (4.9m) were reported along the coast of Mexico and torrential rains triggered flash flooding resulting in ten fatalities.[11][12]
A tropical wave crossed Central America from June 14–16. The system entered the Eastern Pacific basin without much convection. The northward portion of the wave developed a circulation in the mid-levels of the atmosphere, and despite moving over waters marginally suitable for cyclogenesis, the tropical wave organized into the fourth depression of the season on June 22[13] as deep convection developed near the center.[14] At this time, the system was located 460mi (740km) south of the southern tip of the Baja California Peninsula.[13] Early on June 23, the depression intensified into Tropical Storm Blas. Although the storm developed an impressive upper-level outflow and well-organized thunderstorm activity and was moving into an area sea surface temperatures of 78°F (26°C), the National Hurricane Center (NHC) forecast only slight intensification.[15] Water vapor imagery also suggested that strong wind shear would introduce a weakening trend,[16] and later that day, Blas weakened accordingly back into a depression, and dissipated at 0:00 UTC June 24.[13]
Celia formed from tropical wave that crossed over into the East Pacific basin around June 19. Dvorak Classifications were initiated on June 21, and a circulation developed the next day. The system was classified as a tropical depression while located 170mi (270km) west of Guatemala based on ship reports. Upon becoming a tropical cyclone the storm formed further east than most Pacific hurricanes due to little wind shear and warm sea surface temperatures near Central America.[17] Due to these conditions, meteorologists at the NHC were anticipating steady intensification.[18] Although the storm initially appeared ragged on weather satellite imagery,[19] the storm intensified into Tropical Storm Celia on 18:00 UTC June 23 as banding features improved.[17] By the evening of June 24, Celia had developed a large area of convection near the center, and the NHC re-assessed the intensity at 65mph (105km/h). The storm was also forecast to become a moderate Category 2 hurricane on the Saffir-Simpson Hurricane Scale.[20]
Several hours later, Celia was upgraded into a hurricane based on intensity estimates via Dvorak Technique. Celia's rate of intensification accelerated and thus underwent a period of rapid deepening.[17] Overnight, the storm developed an excellent upper-level outflow and very cold cloud tops.[21] Late on June 25, an eye appeared, and the NHC classified the storm as a strong Category 1 hurricane.[22] By midday June 26, Celia intensified into a Category 2 hurricane[6] A well-defined eye soon developed, and the storm was upgraded into a Category 3 hurricane later that day.[23] Early on June 27, Celia became a Category4 major hurricane with winds of 145mph (233km/h) and a minimal pressure of 935mbar (27.6inHg).[24] Celia maintained Category4 intensity for about 24hours and then started to gradually weaken.[24]
Late on June 28, Celia's eye became somewhat ragged,[25] and the storm fluctuated in intensity over the next several days. At 00:00 UTC June 29, Celia weakened to winds of 85mph (137km/h). The system briefly re-intensified into a moderate Category 2 hurricane, but later resumed the weakening trend. Celia fell below hurricane status on 00:00 UTC July 2. Turing northwest, the tropical cyclone weakened back to tropical depression status the next day. Thereafter, Celia degenerated into a tight low to mid-level swirl of low-convection clouds that dissipated July 4.[24]
A tropical wave organized into Tropical Depression Five-E on July 2. It strengthened and was named Darby the next day. Due to very strong steering currents, Darby accelerated as it paralleled the coast of Mexico, and the system strengthened into a hurricane on July 5 while also substantially increasing in size. Darby peaked as a strong Category3 on July 6, before it began to steadily weaken thereafter as it passed over cooler waters. The hurricane weakened into a tropical storm on July 8 and to a depression the next day. Tropical Depression Darby lost all tropical characteristics on July 10, but moisture from Darby's remnants eventually spread over parts of the continental United States.[26]
During Darby's formation, flooding from the cyclone's rainbands killed three people in Acapulco, where 180 shops were damaged. Four fishermen were reported missing, fate unknown. Manzanillo, Colima, reported sustained winds just above tropical-storm force. The hurricane's remnants brought mainly light rain to the U.S. state of California. Cloud cover also delayed the landing of the Space Shuttle Columbia for one day. South-facing beaches of that state were pounded with waves up to 7 feet (2.1m) in height. A monetary value for damage is not available.[27] Darby also caused a few shipping accidents. A pleasure craft, the Oasis, had an engine failure and was abandoned. The seven people aboard were rescued, but the boat was sunk. A smaller sailboat, the Hosanna, had difficulties but was towed to a safe location by a cutter from the United States Coast Guard. A fishing boat at an unspecified location also experienced difficulties.[28]
The origins of Hurricane Estelle were from a tropical wave that began on June 23 off the African coast.[29] After passing over northern South America, a large area of disturbed weather formed about 460mi (740km) west of Acapulco on July 9 and was classified as a tropical depression two days later. Eighteen hours later, the depression strengthened into Tropical Storm Estelle[29] as banding features increased.[30] Gradually intensifying, the storm's outflow improved,[31] and a burst of deep convection occurred over the center.[32] Early on July 10, an eye developed, and based on this, Estelle was upgraded into a hurricane. Around that time, Estelle turned to the northwest.[29]
Although the eye briefly disappeared from satellite imagery later that day,[33] a small and distinct eye quickly re-formed within very deep convection, and Estelle was respectively upgraded into a Category 2 hurricane.[34] Later on July 11, the NHC reported that Estelle had intensified into a major hurricane.[6] A few hours later, Estelle was upgraded into a Category 4 system as the storm continued to rapidly deepen.[35] Moving northwestward due to interaction with a trough,[36] Estelle began a weakening trend. By the afternoon, Estelle was downgraded into a Category 3 system. At 0000 UTC, winds fell below major hurricane force, only to re-intensify back to a major hurricane hours later.[6] Hurricane Estelle quickly re-developed a well-defined eye and an impressive upper-level outflow[37] and Estelle attained its peak intensity of 140mph (230km/h).[6] However, the next day the thunderstorms around the eye began to warm.[38] The storm gradually weakened over the next few days as it encountered cooler waters.[29] By early on July 14, Hurricane Estelle was re-classified as a Category 3 hurricane, and shortly afterwards, winds fell below major hurricane strength several hundred miles west of the Baja California Peninsula.[6] Turning west under shallow low-level steering currents,[29] Estelle weakened into a tropical storm on July 15. It weakened into a tropical storm the next day. On 0800 UTC July 17, Tropical Depression Estelle had dissipated over 1,000mi (1,610km) west of Baja California Sur.[6]
The origins of Hurricane Frank were from a tropical wave that exited the coast of Africa on July1. After reaching the Pacific, it developed an area of disturbed weather on July9 off the southern Mexican coast. Continuing westward, the system developed into Tropical Depression Seven-E on July13 about 660mi (1,060km) south-southeast of the southern tip of the Baja California peninsula.[39] The depression intensified with favorable water temperatures and well-defined outflow. Based on estimates from satellite imagery, the depression intensified into Tropical Storm Frank on July14.[40] For about a day, the storm tracked generally northwestward before turning to the west due to a building ridge north of the system.[39] An eye developed within the Central Dense Overcast, a large mass of deep convection, late on July14. Additional intensification was expected, and Frank was predicted to become a major hurricane within 48 hours.[41] The next day, Frank attained hurricane status.[39]
Late on July15, Hurricane Frank passed about 175mi (282km) south of Socorro Island. A station on the island reported winds of 67mph (108km/h), which indicated that the hurricane had a large wind field.[42] Slow intensification continued, and Frank intensified into a major hurricane, or a Category3 on the Saffir-Simpson Hurricane Scale, on July17.[6] By that time, the eye had become well-defined,[43] and later became surrounded by a ring of deep convection. On July18, Frank reached its peak intensity of 145mph (233km/h) well to the west-southwest of the Baja California peninsula.[44] By July 20, winds dropped below major hurricane intensity, and by the evening, Frank was just a Category 1 hurricane.
Afterward, the hurricane turned northwestward over progressively cooler water temperatures, resulting in weakening. On July21 Frank was downgraded to a tropical storm,[39] after wind shear caused further weakening.[45] The next day, it crossed into the Central Pacific Hurricane Center's area of responsibility,[46] with winds at the time of crossing over were estimated at 50mph (80km/h). Rapidly declining in strength, it weakened to a tropical depression on July23. Later that day Frank dissipated about 800mi (1,300km) northeast of Hawaii.[4]
A tropical wave left Africa in early July and crossed the Atlantic without development. It crossed into the eastern Pacific on July13, and organized into Tropical Depression Eight-E on July 14.[47] The system was located over warm waters,[48] and moving west-northwest, the depression paralleled the coast of Mexico and strengthened into Tropical Storm Georgette on July15.[47] About 18hours later, Georgette became a minimal hurricane after deep convection developed over the center.[47][49] During its formative stages, Georgette brought higher than average humidity to California.[50] The hurricane turned westward due to a ridge to the north, but a west-northwest track later resumed. On July 18, Georgette reached a peak of 110mph (180km/h) and a minimum pressure of 964mbar (28.5inHg),[47] although the NHC operationally estimated peak winds of 115mph (185km/h).[51]
Shortly after its peak, the eye became less defined,[52] only intermittently seen on satellite imagery.[53] After wind shear increased, Georgette weakened for about two days, and on July20 a ridge forced the hurricane southwestward.[54] Similar to hurricanes Celia and Estelle earlier this season, Georgette re-intensified once it turned back toward the west and it regained its peak intensity as a Category 2 hurricane on July 21.[47] Although meteorologists predicted the storm to intensify into a major hurricane,[55] this did not occur.[6] Strong upper-level winds weakened Georgette back to a tropical storm early on July 23.[47] About 30 hours later, it weakened to a tropical depression, devoid of deep convection,[54] and shortly thereafter entered the Central Pacific Hurricane Center's area of responsibility.[54] Moving quickly westward, Georgette had difficulty maintaining a closed atmospheric circulation, and it dissipated late on July26. Around that time, the system was south of Hawaii, and it brought locally gusty winds as high as 60mph (95km/h) to the northern part of the Big Island. Several large waterspouts were sighted early on July 26 off of a beach in the south Kohala district. Georgette's remnants later produced squally weather at Johnston Atoll. The remnants moved across the International Dateline into the western Pacific on July 29, and was still a weak tropical disturbance when it moved past Wake Island at the end of the month.[4]
On July 26 a tropical depression formed and became a weak tropical storm the next day. It steadily organized, ad reached it peak intensity as a strong tropical storm. It then began to weaken, despite being located over warm waters. Howard dissipated several days later without affecting land.[56]
Isis formed on July 28 as a depression and became a tropical storm the next day. Isis peaked as a strong tropical storm with 65mph (105km/h) winds on July 30. Due to cooler water, it weakened to a depression on the first and dissipated the next day. Isis degenerated to a broad area of low pressure on August 2.[57]
Hurricane Javier probably originated from a tropical wave that left Africa on July 17. While it showed some signs of organization off the west coast of Africa, most of the convection dissipated by time it was near the Lesser Antilles. Around the time it entered the Pacific on July 27, thunderstorm activity increased and became more concentrated. By July 30, the cloud pattern began to organize, though it was initially elongated. Moving westward, the system was declared a tropical depression on 1800 UTC July 30.[58]
Initially, the depression developed slowly and there was even uncertainty on whether it had an atmospheric circulation or not. It was not until 1200 UTC August 2 when the system was finally upgraded into a tropical storm. Around this time, Javier turned west-northwest, a direction it would maintain for days when a ridge north of the cyclone caused it turn to the west, and later, west-southwest. Shortly after turning west, Javier intensified into a hurricane.[58]
By 0000 UTC August 6, Hurricane Javier had attained peak wind speeds of 80mph (130km/h). After hanging on to hurricane strength for a day, Javier rapidly lost deep convection and become much less organized. By August 7, winds were only 50mph (80km/h). However, the weakening rate slowed somewhat once Javier before it moved CPhC's AOR on August 8.[58] Tropical Storm Javier continued to diminish in strength while moving west-southwest. On August 9, the CHPC reported that Javier had weakened into a tropical depression. By 0000 UTC August 12, Javier had dissipated south of Hawaii. As a dissipating tropical depression, some rainfall and showers were recorded along the Hawaiian islands.[4]
A depression formed on August 18. It became a tropical storm shortly after forming and was named Kay. Kay was a short lived system. Its peak intensity was only 50mph (80km/h). However, Kay was a very small tropical storm. It dissipated on August 22. Kay never impacted land.[59]
Tropical Depression Fourteen-E formed on August 20 from a tropical wave that began to show signs of organized on August 19. At the time of the upgrade, it was located about 275 miles (443km) south-southwest of Manzanillo. The depression slowly strengthened and steadily organized attained tropical storm status late on August 20. The next day, Lester turned to the north. Lester intensified into a hurricane late on August 22 while located about 240 miles (390km) west of La Paz. The hurricane continued to organize and Lester attained peak winds of 85mph (137km/h) on August 23 before making landfall as a minimal hurricane near Punta Abreojos, Baja California Sur. After passing through the northern Gulf of California, it made a second landfall in the state of Sonora as a tropical storm.[60] Lester entered Arizona as a tropical storm on August 24, the first time since 1967 that a Pacific hurricane entered the United States as a tropical storm. The low-level circulation subsequently dissipated over New Mexico,[61] though the remnants transitioned into an extratropical cyclone,[62] and subsequently merged with the remnants of Hurricane Andrew and another frontal system on August 29.[63]
Hurricane Lester produced heavy rainfall across its path with a peak rainfall occurring in Mulege.[64] Extensive flood damage was reported west of Hermosillo. A large highway was damaged and many communities were destroyed.[65] Flash flooding from Lester caused 10,000 people to be evacuated from their homes.[66] In addition, mudslides killed three people,[67] and left 5,000homeless.[65] The remnants of Lester produced heavy rainfall across the Southwestern United States[64] causing flash flooding of arroyos and [68] moderate flooding in Denver. Snowfall from the storm generated traffic problems in mountainous areas.[69] The remnants of Lester extended through the eastern United States,[64] resulting in rainfall records in Minnesota, Nebraska, Colorado, and North Dakota.[70] In all, Hurricane Lester resulted in $3million (1992USD) in damage.[67]
Far in the open ocean, a tropical wave organized into Tropical Depression Fifteen-E on August 27. Banding and convection increased, and the depression became a tropical storm the next day. Development continued, and Madeline peaked with a minimum pressure of 999mbar (29.5inHg), and winds of 50mph (80km/h), on August 29. As the system progressed westward, it entered a region of strong wind shear and had dissipated on August 31. The system never came near land.[71]
Newton was a fairly short-lived storm. It formed from a tropical wave on August 27. It became a tropical storm, was named Newton 18 hours later, and dissipated four days later on August 31. Newton never impacted any land.[72]
Tropical Depression Seventeen-E formed in September 2, rapidly intensifying to a tropical storm the next day, being assigned the name Orlene, then it strengthened into a Category 1 hurricane late that day. Orlene peaked at Category 4 major hurricane status on September 6. The system held intensity for a day or so, with gradual weakening due to shear over the area, but the shear relaxed over the cyclone early on September 9, which brought about a quick restrengthening phase on September 9, although it stopped, and the weakening trend resumed later that day. Orlene downgraded back to a tropical storm on September 10, and finally a depression on September 12, around the same time that it moved into the Central Pacific.[73] It dissipated two days later, on September 14, after making landfall as a tropical depression on the Big Island of Hawaii. The remnants caused downpours and washed out roads, and the damage was minimal, though some areas got up to 4in (100mm) of rain.[74]
Forming on September5 about 1,700 miles (2,700km) southwest of Cabo San Lucas, the depression continued quickly westward and remained weak until September 8, when it strengthened into a tropical storm. Having been designated in the Central Pacific, the storm was given the name Iniki. Iniki continued westward and strengthened over the unusually favorable central Pacific; it reached hurricane status on September 9 while 470 miles (760km) south-southeast of Hilo. The subtropical ridge, which typically keeps hurricanes well away from the Hawaiian Islands, weakened due to an approaching upper level-trough and allowed Iniki to turn to the northwest. With very favorable upper-level outflow and warm water temperatures, Iniki steadily intensified, and attained major hurricane status on September 10 while south-southwest of the island chain. As Iniki turned to the north, it continued to strengthen, reaching a peak of 145mph (233km/h) winds on September 11 while 170 miles (270km) south-southwest of Kauaʻi. It continued rapidly to the north-northeast, and made landfall as a Category4 hurricane on the Saffir-Simpson Hurricane Scale.[4]
After crossing the island, Iniki weakened rapidly, and became extratropical on September 13 about halfway between Alaska and Hawaiʻi.[4] The Central Pacific Hurricane Center (CPHC) failed to issue tropical cyclone warnings and watches for the hurricane well in advance as the CPHC forecast Iniki to remain well south of the island chain until September 10, less than 24hours before landfall that any warning was given to the public.[75] Iniki's large wind field caused nearly 30,000people to evacuate to 110public shelters in Oʻahu.[76]
Hurricane Iniki's high winds caused extensive damage in Kauaʻi. 1,421houses were completely destroyed, and 63 were lost from the storm surge and wave action. A total of 5,152homes were severely damaged, while 7,178 received minor damage.[4] Iniki's high winds also downed 26.5% of the island's transmission poles, 37% of its distribution poles, and 35% of its 800-mile (1,300km) distribution wire system.[77] Some areas were without power for up to three months after the storm.[4] More than 7,000people were homeless after the storm's passage.[77] One person died when struck by debris, while another died when a portion of her house fell on her. Offshore, two humans died when their boat capsized. More than 100injuries can be attributed to Iniki.[4]
Upon passing by Oʻahu, Iniki produced tides of 1.7–3 feet (0.52–0.91m) above normal.[76] Prolonged periods of high waves severely eroded and damaged the southwestern coast of Oʻahu.[4] In all, Hurricane Iniki caused several million dollars in property damage,[76] and two deaths on Oʻahu.[4] Overall, Iniki was the costliest hurricane to strike the state of Hawaiʻi, causing $3.1billion in damage.[78] In all, Iniki also was responsible for 6deaths.[4] During the aftermath of the storm, communities held parties to necessarily consume perishable food from unpowered refrigerators and freezers. Kauaʻi citizens remained hopeful for monetary aid from the government or insurance companies, though after six months they felt annoyed with the lack of help.[79] though military effectively provided aid for their immediate needs.[80]Amateur radio proved to be helpful during the three weeks after the storm, with volunteers coming from around the Pacific to assist in the recovery.[81] Local operators assisted with the American Red Cross to provide disaster relief centers across Kauai.[82] Many insurance companies left Hawaiʻi after the storm, forcing Hawaii to launch a Hurricane Relief Fund in 1993 to help unprotected Hawaiʻi residents, but it was stopped in 2000.[83]
The tropical wave from which Paine originated moved off the coast of Africa on August 25, reaching the Caribbean on September 2, and eventually crossed Central America and the Yucatán Peninsula. The wave finally reached the Pacific on September 8, developing a mid-level circulation a short distance south of Manzanillo. The circulation finally organized enough to be classified as Tropical Depression Nineteen-E early on September 11, a couple hundred miles southwest of Baja California. The depression continued just south of due west for the next couple of days, under the influence of a deep-layer-mean anticyclone. The depression soon intensified into Tropical Storm Paine around 1800 UTC on the September 11.[84] Gradually intensifying, the storm approached hurricane intensity early on September 13.[6] Upon the formation of an eye,[84] Paine attained hurricane status.[6] Meanwhile, the storm reached its peak intensity of 75mph (121km/h), a mid-level Category 1 hurricane.[84]
Paine then slowed to a forward speed of only 2–4mph (3.2–6.4km/h), while executing a slow, erratic clockwise loop for the next three days. The loop was initially caused by an approaching trough, but was later caused by Paine's proximity to the approaching Hurricane Roslyn from the east. By 1800 UTC September 14, Paine weakened back to a tropical storm. By September 16, Paine had dissipated. The remnants of Hurricane Paine were later absorbed into Roslyn's larger circulation.[84]
On September 13, a tropical wave developed into Tropical Depression Twenty-E, about 416mi (669km) south of Baja California. Despite initial disorganization, the system developed an eye-like feature the next day and was named Tropical Storm Roslyn, the storm also began to develop banding features, concurrent with the better establishment of upper-level outflow. Roslyn quickly intensified to just below hurricane status on the September 15, but began a short weakening trend, as it passed through the wake of Hurricane Paine, where it had begun intensifying on the 11th. By 1800 UTC that day, Roslyn began interacting with the weakening and nearby Paine, with centers of both systems being only a few hundred miles apart, and with this interaction, Paine was absorbed into Roslyn the next day, although this merger didn't affect Roslyn's intensity in the least. On the September 18, Roslyn had a brief period of strengthening. By September 21, deep convection began to rapidly increase, followed by a visible eye on satellite imagery the next day, which indicated that Roslyn had reached hurricane intensity. The hurricane peaked at moderate Category 2 status later on the September 22, with a quick decrease in strength thereafter. Roslyn was downgraded to a tropical storm just as it crossed into the Central Pacific two days later, and over the next several days, a trough to the west turned the weakening Roslyn to the northeast, and then to the north. The system finally dissipated on September 30, over two weeks after it formed.[85]
On September 17, a tropical wave was upgraded into a tropical depression. The next day, the depression strengthened into Tropical Storm Seymour a couple hundred miles south of the southern tip of Baja California, and while continuing on a west-northwest and northwest track, Seymour reached hurricane strength on September 19. However, the system soon weakened to a tropical storm, due to the effects of a trough producing moderate shear, and cooler waters. This was short-lived. The trough soon moved out of the area and was replaced by a ridge, which steered Seymour to the west, and allowed it to regain hurricane status on the September 23, while Seymour had developed a broad and clear eye. However, Seymour only held hurricane intensity for a short period of time, and by that night, it had already weakened back to a tropical storm. After losing a significant amount of deep convection, it weakened to a depression two days later. Tropical Depression Seymour finally dissipated on September 27. Seymour never affected land, and no damage or deaths were reported.[86]
A tropical wave exited the African coast on September 5, which eventually reached the Pacific and became more defined on September16 to the south of Mexico.[87] At 1200 UTC on September 17, Tropical Depression 22E developed, becoming Tropical Storm Tina the next day.[88][89] Tina reached hurricane status at 1800 UTC on September 20, reaching winds of 85mph (137km/h) before wind shear weakened it, and deep convection decreased.[87] Tina briefly weakened back into a tropical storm, but regained hurricane intensity for another two days.[89] On September25, data from a Hurricane Hunter aircraft indicated that Tina weakened back to a tropical storm.[87] The storm took a sharp turn north-northeast towards Mexico, due to passing trough weakening the subtropical ridge. After two days moving toward Mexico, Tina turned back westward as a ridge built to the north. Entering an area of lower wind shear, Tina regained hurricane status on September 28, and quickly attained major hurricane status. After passing near Clarion Island, Tina attained peak intensity on September30, with winds of 150mph (240km/h) and a minimum pressure of 932mbar (27.5inHg). This made it the strongest hurricane of the season. Soon after, Tina turned to the northwest into an area of cooler waters and stronger wind shear. It weakened to tropical storm status on October4, and soon after only had limited thunderstorms near the center. On October7, Tina fell to tropical depression status as it turned back to the west, generating intermittent convection. Two days later, the circulation crossed 140ºW into the central Pacific. Tina curved to the north, dissipating on October11.[90]
Due to its erratic track and slow motion, Tina was alive from September 17 to October 11— a span of 24days. This is the record for the eastern Pacific Ocean, smashing the east/central record of 20days held by Hurricane Fico in the 1978 season and surpassing Typhoon Rita's west Pacific 1972 record. It was itself surpassed just two years later by Hurricane John.[90]
On October 1, a tropical wave organized into Tropical Depression Twenty Three-E, a few hundred miles south of the Mexican coast. Despite weak shearing over the system, it became Tropical Storm Virgil later that day, rapidly intensifying to a hurricane on the October 2, when a distinct and well defined eye appeared on satellite images. Virgil was originally on a slow northwest track, but a mid-upper-level trough turned the hurricane to the north early on October 3. Despite the change in track, the hurricane reached a peak at minimal Category 4 status around the same time that it turned to the north that day. Virgil continued north until early on October 4, when it turned to the northwest and made landfall at high Category 2 strength, halfway between Manzanillo and Lázaro Cárdenas, and after landfall, the system was quickly weakened over the mountainous terrain of Mexico, passing to the north of Manzanillo late on the October 4.[91] Shortly after passing over Manzanillo, it weakened below tropical storm strength, and early on October 5, the weakened Tropical Depression Virgil exited into the Pacific, but no regeneration was expected, as strong westerlies and the weakened state of the system prevented any regeneration, and it dissipated shortly thereafter.[92]
Because Virgil made landfall in a sparsely populated area, damage from storm surge was minimal. The chief effect was heavy rain and flooding, peaking at over 10in (250mm) in one location.[5]
An area of disturbed weather developed into Tropical Depression Twenty Four-E a few hundred miles south of Acapulco. The next day, it was upgraded into Tropical Storm Winifred when satellite imagery showed increased convective banding features around the storm's center. Winifred was upgraded to a hurricane on October 8, subsequently an eye appeared on satellite imagery. Hurricane Winifred peaked at Category 3 status the next day, turning to the north-northeast just hours before landfall. Initially, the storm maintained major hurricane intensity; however, the eye had disappeared hours prior to landfall. Based on this, Winifred weakened into a Category 2 hurricane. On October 9, it made landfall just east-southeast of Manzanillo. At the time it was a weak Category 2 hurricane with winds of 110mph (180km/h) and a central pressure of 975mb (28.8inHg). After moving ashore, Hurricane Winifred rapidly weakened to a depression over the mountainous terrain of Mexico by October 10, while continuing on a northeast track and finally degenerating to a remnant low later that day.[93]
Three people were killed by floods. Damage was concentrated in Colima and Michoacán. High waves flooded portions of Highway 200 between Zihuatenajo, Ixtapa, and Lázaro Cárdenas. Electricity and water systems was knocked out in Colima. About 84,000ha (210,000 acres) of farmland were damaged. Total damage in one state was estimated at 16000 pesos (1992 MXP) or $5 million (1992 USD$, 10.9million2024USD).[94] The highest point maximum reported was of 16.7in (420mm), recorded at Lázaro Cárdenas, Michoacán.[95] Elsewhere, Winifred forced a temporary closure of the port of Acapulco.[96]
On October 13, a tropical wave developed a visible low level circulation center, developing into Tropical Depression Twenty Five-E later that day, several hundred miles south of Baja California. The system quickly reached tropical storm status, while moving west at about 14mph (23km/h). On October 17, Xavier dissipated several hundred miles south of the tip of Baja California, the remnants were tracked for several days, until it moved out of range of available satellites. Xavier was only the second tropical system to be named with an 'X' in the eastern Pacific basin, after 1985's Xina. Xavier formed at sea, and therefore, no deaths or damages are associated with it.[97]
On October 15 a tropical depression formed from the wave several hundred miles south of Manzanillo, and on October 16, it strengthened into Tropical Storm Yolanda. The storm turned to the northwest later that day, and maintained this track for the rest of its lifespan. Yolanda peaked as a strong tropical storm on October 19, but strong southwesterly shear removed all deep convection within the storm's circulation later that day, although there were several occasional flare-ups of convection for the next 12 hours or so. The storm weakened back to a depression the next day, while steering currents moved the weakening depression's center to the southwest, and then finally the west before dissipating in the Central Pacific on the October 22. Due to the fact that it formed at sea, no deaths or damages are associated with the storm.[98]
A tropical wave exited western Africa on October6, eventually crossing Central America into the eastern Pacific between October21–23. Over the following few days, convection gradually increased and the system became better organized. On October25, the NHC classified it as Tropical Depression Twenty-Seven-E, about 805mi (1,296km) south of the southern tip of Baja California Sur, Mexico.[99] Upon being classified, the depression was relatively disorganized, but deep convection had maintained itself near the center of circulation.[100] Throughout October25, banding features developed and the upper-level outflow became better established, with the environment characterized by low wind shear and warm sea surface temperatures. In response to a ridge to the east, the depression tracked in a general west-northwest direction.[101] On October26, the depression intensified into Tropical Storm Zeke, the record-breaking twenty-fourth named storm of the year.[99] Wind shear from a trough caused Zeke's convection to lessen around the center, causing the system to weaken back to tropical depression status on October27. Around that time, Zeke turned to the north, steered by the trough.[102][99][103][104]
Late on October27, convection redeveloped over the center of circulation, allowing the storm to re-attain tropical storm intensity on October28. The strengthening followed the passage of a shortwave trough; however, shear over the system remained strong.[105] Despite the unfavorable conditions, Zeke maintained its intensity, through intermittent bursts of convection, and began to turn towards the northeast.[106][107] Late on October29, a large burst of deep convection over the center of the storm allowed for intensification.[108] Around this time, the storm attained its peak intensity with winds of 50mph (80km/h) with a barometric pressure of 1000mbar (1000hPa; 30inHg).[99] Not long after attaining its peak intensity, Zeke began to weaken once more due to increasing westerly wind shear.[99] By the early morning of October30, the center of circulation became devoid of thunderstorm activity and the system had turned eastward.[109] Later that day, Zeke weakened to a tropical depression before degenerating into a remnant low pressure system. The NHC continued to monitor the low-level swirl of clouds associated with Zeke for several more days as the system meandered several hundred miles south of Baja California Sur.[99]
Due to Zeke's potential to affect the Baja California peninsula, the Government of Mexico issued a tropical storm warning for between Cabo San Lázaro and Los Burros, and a tropical storm watch for areas along mainland Mexico between Los Mochis, Sinaloa and Puerto Vallarta.[110] Although the center of the storm never moved over land, the system's outer bands brought locally heavy rain and gusty winds to parts of Sinaloa and Jalisco.[111]
Other systems
Tropical Depression Two-E developed during June 16, about 1,700km (1,055mi) to the southwest of Mexico City.[6] Over the next few days the system moved north-westwards, but did not develop any further and dissipated on June 18.[5][6]
During September 24, a tropical disturbance developed within the trade-wind trough of low pressure, just to the east of the International Dateline.[112] Over the next few days the system gradually developed further as it moved north-westwards, before it was classified as Tropical Depression 21W by the JTWC during September 26.[112] The system subsequently moved out of the Central Pacific basin and into the Western Pacific, where it was immediately classified as a tropical storm by both the JTWC and the Japan Meteorological Agency and named Ward by the former.[112][113]
During October 23, a tropical disturbance developed within the trade-wind trough of low pressure about 830km (515mi) to the south of Johnston Island.[112] Over the next day atmospheric convection surrounding the systems low level circulation increased, as it moved towards the International Dateline.[112] During October 24, it was classified as Tropical Depression 27W, by the JTWC in coordination with the CPHC because of its proximity to the Western Pacific basin.[112] 27W subsequently gradually intensified further, before it was classified as a tropical storm and named Dan by the JTWC, just after it had moved into the Western Pacific basin.[112]
During November a small tropical disturbance developed, within a cloud mass over 1,000km (620mi) to the southwest of Hawaii's Big Island.[4] Over the next few days, the system moved westwards and developed a closed circulation, before it was designated as Tropical Depression 03C by the CPHC during November 21.[4] The system continued to move westwards over the next 24 hours but did not develop any further and dissipated during November 23.[4][6]
The following list of names was used for named storms that formed in the North Pacific Ocean east of 140°W in 1992.[114] This was the same list used for the 1986 season.[115] The NHC exhausted the naming list on October25 when it named Tropical Storm Zeke, marking the first time that a storm name beginning with the letter "Z" was used on record in the basin. Zeke also continued the record of named storms in a single season in the eastern Pacific, being the 24th and final tropical storm.[99][116][117] Storms were named Seymour, Tina, Virgil, Winifred, Xavier, Yolanda, and Zeke for the first time in 1992.[118] No names were retired from the list following the season, and it was used again for the 1998 season.[119]
For storms that form in the North Pacific from 140°W to the International Date Line, the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list.[114][120] Three named storms, listed below, formed in the central North Pacific in 1992. Named storms in the table above that crossed into the area during the year are noted (*).[4]
This is a table of all of the tropical cyclones that formed in the 1993 Pacific hurricane season. It includes their name, duration (within the basin), peak classification and intensities, areas affected, damage, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 1992 USD.
The 2004 Pacific hurricane season was an overall below-average Pacific hurricane season in which there were 12 named tropical storms, all of which formed in the eastern Pacific basin. Of these, 6 became hurricanes, and 3 of those intensified into major hurricanes. No storms made landfall in 2004, the first such occurrence since 1991. In addition to the season's 12 named storms, there were five tropical depressions that did not reach tropical storm status. One of them, Sixteen-E, made landfall in northwestern Sinaloa. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central Pacific basin. It officially ended in both basins on November 30. These dates conventionally delimit the period during each year when most tropical cyclones form in each respective basin. These dates conventionally delimit the period during each year when a majority of tropical cyclones form. The season was reflected by an accumulated cyclone energy (ACE) index of 71 units.
The 2001 Pacific hurricane season was a relatively near-average Pacific hurricane season which produced fifteen named storms, though most were rather weak and short-lived. Only eight hurricanes formed and two major hurricanes. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.
The 2000 Pacific hurricane season was an above-average Pacific hurricane season, although most of the storms were weak and short-lived. There were few notable storms this year. Tropical storms Miriam, Norman, and Rosa all made landfall in Mexico with minimal impact. Hurricane Daniel briefly threatened the U.S. state of Hawaii while weakening. Hurricane Carlotta was the strongest storm of the year and the second-strongest June hurricane in recorded history. Carlotta killed 18 people when it sank a freighter. Overall, the season was significantly more active than the previous season, with 19 tropical storms. In addition, six hurricanes developed. Furthermore, there were total of two major hurricanes.
The 1998 Pacific hurricane season was a fairly average Pacific hurricane season. Despite this, it had nine hurricanes and six major hurricanes, which was well above average. The season officially started on May 15 in the eastern Pacific and on June 1 in the central Pacific, and ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in that region. The first tropical cyclone developed on June 11, about ten days later than the normal start of the season. The final storm of the year, Hurricane Madeline, dissipated on October 20. Storm activity in the Central Pacific Hurricane Center's warning zone was low, with just one tropical depression observed in the region. Two tropical cyclones from the eastern Pacific also entered the central Pacific; the former did so as a hurricane.
The 1991 Pacific hurricane season was a near-average Pacific hurricane season. The worst storm this year was Tropical Storm Ignacio, which killed 23 people in Mexico and injured 40 others. Elsewhere, Hurricane Fefa caused flooding in Hawaii. Hurricane Kevin was the strongest system of the season and became the then longest-lasting hurricane in the eastern north Pacific basin at the time, and Hurricane Nora was the strongest November storm to that point. The season officially started on May 15, 1991, in the eastern Pacific, and on June 1, 1991, in the central Pacific. It lasted until November 30, 1991, in both basins. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.
The 1990 Pacific hurricane season was a very active season which observed 21 named storms within the basin. The season also produced the fourth highest ACE index value on record. The season was officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 1990 by the formation of the season's first named storm, Hurricane Alma, on May 12. At the time, this was the earliest formation of a tropical storm on record in the eastern Pacific
The 1989 Pacific hurricane season was a near normal season. It officially started on May 15, 1989, in the eastern Pacific, and on June 1, 1989, in the central Pacific, and lasted until November 30, 1989. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. A total of 18 storms and 9 hurricanes formed, which was near long-term averages. Four hurricanes reached major hurricane status on the Saffir–Simpson scale.
The 1988 Pacific hurricane season was the least active Pacific hurricane season since 1981. It officially began May 15, in the eastern Pacific, and June 1, in the central Pacific and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The first named storm, Tropical Storm Aletta, formed on June 16, and the last-named storm, Tropical Storm Miriam, was previously named Hurricane Joan in the Atlantic Ocean before crossing Central America and re-emerging in the eastern Pacific; Miriam continued westward and dissipated on November 2.
The 1986 Pacific hurricane season featured several tropical cyclones that contributed to significant flooding to the Central United States. The hurricane season officially started May 15, 1986, in the eastern Pacific, and June 1, 1986 in the central Pacific, and lasted until November 30, 1986 in both regions. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. A total of 17 named storms and 9 hurricanes developed during the season; this is slightly above the averages of 15 named storms and 8 hurricanes, respectively. In addition, 26 tropical depressions formed in the eastern Pacific during 1986, which, at the time, was the second most ever recorded; only the 1982 Pacific hurricane season saw a higher total.
The 1980 Pacific hurricane season officially started May 15, 1980, in the eastern Pacific and June 1, 1980, in the central Pacific, lasting until November 30, 1980. These dates conventionally delimit each year when most tropical cyclones form in the northeastern and central Pacific Ocean. This season was relatively uneventful; since no tropical cyclones made landfall, there were no reports of casualties or damage.
The 2010 Pacific hurricane season was the least active Pacific hurricane season on record, tied with 1977. The season accumulated the second-fewest ACE units on record, as many of the tropical cyclones were weak and short-lived. Altogether, only three of the season's eight named storms strengthened into hurricanes. Of those, two became major hurricanes, with one, Celia, reaching Category 5 intensity on the Saffir-Simpson scale. Despite the inactivity, however, it was the costliest Pacific hurricane season on record at the time, mostly due to Tropical Storm Agatha. The season officially began on May 15 in the eastern North Pacific and on June 1 in the central North Pacific. It ended in both regions on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of the Pacific. However, the formation of tropical cyclones is possible at any time of the year, as evidenced by the formation of Tropical Storm Omeka on December 19. This was below normal hurricane season was since 1996, had 9 named storms. Only 2010 had 8 named storms.
The 2011 Pacific hurricane season was a below average season in terms of named storms, although it had an above average number of hurricanes and major hurricanes. During the season, 13 tropical depressions formed along with 11 tropical storms, 10 hurricanes and 6 major hurricanes. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. The season's first cyclone, Hurricane Adrian formed on June 7, and the last, Hurricane Kenneth, dissipated on November 25.
Hurricane Elida was the first of three tropical cyclones of the 2002 Pacific hurricane season to reach Category 5 strength on the Saffir-Simpson Hurricane Scale. Elida was one of only sixteen known Category 5 hurricanes in the eastern north Pacific tropical cyclone basin, east of the International Date Line and north of the Equator. Although heavy waves affected the Mexican coastline due to Elida, no damages or casualties were reported in relation to the hurricane.
Hurricane Gilma was one of the most intense Eastern Pacific tropical cyclones on record and the second of three Category 5 hurricanes during the active 1994 Pacific hurricane season. Developing from a westward tracking tropical wave over the open waters of the eastern Pacific Ocean on July 21, the pre-Gilma tropical depression was initially large and disorganized. Gradual development took place over the following day before rapid intensification began. By July 23, the storm intensified into a hurricane and later a Category 5 storm on July 24. As Gilma reached this intensity, it crossed into the Central Pacific basin, the fourth consecutive storm to do so.
The 2016 Pacific hurricane season was tied as the fifth-most active Pacific hurricane season on record, alongside the 2014 season. Throughout the course of the year, a total of 22 named storms, 13 hurricanes and six major hurricanes were observed within the basin. Although the season was very active, it was considerably less active than the previous season, with large gaps of inactivity at the beginning and towards the end of the season. It officially started on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific ; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in these regions of the Pacific Ocean. However, tropical development is possible at any time of the year, as demonstrated by the formation of Hurricane Pali on January 7, the earliest Central Pacific tropical cyclone on record. After Pali, however, no tropical cyclones developed in either region until a short-lived depression on June 6. Also, there were no additional named storms until July 2, when Tropical Storm Agatha formed, becoming the latest first-named Eastern Pacific tropical storm since Tropical Storm Ava in 1969.
The 2010 Pacific hurricane season was one of the least active seasons on record, featuring the fewest named storms since 1977. The season officially started on May 15 in the eastern Pacific—east of 140°W—and on June 1 in the central Pacific—between the International Date Line and 140°W—and lasted until November 30. These dates typically cover the period of each year when most tropical cyclones form in the eastern Pacific basin. The season's first storm, Tropical Storm Agatha, developed on May 29; the season's final storm, Tropical Storm Omeka, degenerated on December 21.
Hurricane Celia was the second-earliest forming Category 5 hurricane in the Eastern Pacific on record, after 1973's Hurricane Ava. The fourth tropical cyclone, third named storm, first hurricane, and first major hurricane of the very inactive 2010 Pacific hurricane season, Celia formed from a tropical wave about 370 mi (595 km) southeast of Acapulco, Mexico on June 18, Celia quickly organized as deep convection consolidated around the center, attaining hurricane status by June 20. Over the following days, the hurricane's winds fluctuated as wind shear impeded significant development hindering it from becoming potentially dangerous. Once this shear lightened on June 24, the storm rapidly intensified to attain its peak strength with winds of 160 mph (255 km/h) and an estimated barometric pressure of 921 mbar. Not long after reaching this strength, wind shear increased and the system entered a dry, stable environment. Over the following 42 hours, Hurricane Celia's sustained winds decreased to tropical storm force and the system began to stall over the open ocean by June 27. Despite highly unfavorable conditions, the storm managed to retain tropical storm status through June 28 and degenerated into a non-convective remnant low that evening. The remnants of Celia drifted northward, completing a counter-clockwise loop, and dissipated on June 30, 2010.
The 1992 Pacific hurricane season was the most active season on record, featuring 27 named storms. The season officially started on May 15, in the Eastern Pacific—designated as the area east of 140°W—and on June 1, in the Central Pacific, which is between the International Date Line and 140°W. The season officially ended in both basins on November 30. These dates typically limit the period of each year when most tropical cyclones form in the eastern Pacific basin. Lasting 24 days, Hurricane Tina became the longest lived North Pacific tropical cyclone on record. Its longevity broke the old record for the Eastern and Central Pacific of 20 days, set by Hurricane Fico in 1978; and the old record for the Western Pacific of 22 days, set by Typhoon Rita in 1972.
The 2019 Pacific hurricane season was an above average season which produced nineteen named storms, most of which were rather weak and short-lived. Only seven hurricanes formed, the fewest since 2010. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. This season was one of the latest-starting Pacific hurricane seasons on record, with the first tropical cyclone, Hurricane Alvin, forming on June 25. The final system, Tropical Depression Twenty-One-E, dissipated on November 18.
The 2022 Pacific hurricane season was a slightly above average hurricane season in the eastern North Pacific basin, with nineteen named storms, ten hurricanes, and four major hurricanes. Two of the storms crossed into the basin from the Atlantic. In the central North Pacific basin, no tropical cyclones formed. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central; both ended on November 30. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention.
