The 2002 Pacific hurricane season was a near–average season which produced fifteen named storms. Eight hurricanes formed, including a record-equaling three Category 5 hurricanes, a record it shares with the 1994 and 2018 seasons. It was also a near-average season in terms of accumulated cyclone energy (ACE), having an ACE of 125. The season officially began on May 15, 2002 in the East Pacific Ocean, and on June 1, 2002 in the Central Pacific; both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclone formation occurs in these regions of the Pacific. The first system of the 2002 season, Hurricane Alma, formed on May 24, and the last, Tropical Depression Sixteen-E, dissipated on November 16.
The 1997 Pacific hurricane season was a very active hurricane season. With hundreds of deaths and hundreds of millions of dollars in damage, this was one of the deadliest and costliest Pacific hurricane seasons on record. This was due to the exceptionally strong 1997–98 El Niño event. The 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 almost all tropical cyclones form in the northeastern Pacific Ocean.
The 1996 Pacific hurricane season had below normal tropical cyclone activity, producing 9 tropical storms, of which 5 became hurricanes, with 2 of those intensifying into major hurricanes. With an Accumulated cyclone energy (ACE) index of 53.9, the season ranks among the least intense Pacific hurricane seasons on record. It officially began May 15, 1996, in the eastern north Pacific and on June 1, 1996, in the central north Pacific. It ended on November 30, 1996. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The season slightly exceeded these bounds when tropical storm One-E formed on May 13.
The 1987 Pacific hurricane season was the last year in which the Eastern Pacific Hurricane Center was the primary warning center for tropical cyclones in the eastern Pacific Ocean. The season officially started May 15, 1987, in the eastern Pacific, and June 1, 1987, in the central Pacific, and lasted until November 30, 1987. These dates conventionally delimit the period of each year when the vast majority of tropical cyclones form in the northeastern Pacific Ocean.
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 1983 Pacific hurricane season was the longest season ever recorded at that time. It was a very active Pacific hurricane season. The season started on May 15, 1983 in the eastern Pacific, and on June 1, 1983 in the central Pacific, and lasted until November 30, 1983. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. During the 1983 season, there were 20 named storms, which was slightly less than the previous season. Furthermore, twelve of those storms became hurricanes. And eight of the storms reached major hurricane status, or Category 3 or higher on the Saffir–Simpson hurricane wind scale (SSHWS). The decaying 1982–83 El Niño event likely contributed to this level of activity. That same El Niño influenced a very quiet Atlantic hurricane season.
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 1973 Pacific hurricane season was a below average, with twelve named tropical cyclones in total. Seven storms became hurricanes, of which three were major. The season officially started May 15, 1973, in the eastern Pacific, and June 1, 1973, in the central Pacific, and lasted until November 30, 1973. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.
The 1976 Pacific hurricane season was a very deadly and costly season. Hurricanes Kathleen, Liza, and Madeline were the most notable storms this year. Hurricane Kathleen caused death and destruction in California and Arizona due to flooding. Hurricane Liza was the deadliest storm of the season when it killed over 600 people in Mexico. Hurricane Madeline is notable for being one of the most intense Pacific hurricanes at landfall.
The 1975 Pacific hurricane season officially started May 15, 1975, in the eastern Pacific, and June 1, 1975, in the central Pacific, and lasted until November 30, 1975. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean.
The 1970 Pacific typhoon season has no official bounds; it ran year-round in 1970, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1972 Pacific hurricane season was an ongoing event in tropical cyclone meteorology. There were few notable storms this year. Only one person was killed and storm effects were almost not serious at all. The most notable systems were Hurricane Celeste and Joanne. Celeste was the strongest storm of the season, and caused heavy damage to Johnston Atoll. Hurricane Joanne brought gale-force winds to the Continental United States and caused flooding in Arizona and northern Mexico, which killed one person. The only other system to directly impact land was Hurricane Annette.
The 1961 Pacific hurricane season was an event in meteorology. It officially started on May 15, 1961, in the eastern Pacific and lasted until November 30, 1961. Ten tropical cyclones, 9 named storms and two hurricanes formed during the 1961 season, none of the hurricanes reached beyond category 1 status on the Saffir-Simpson Hurricane Scale.
The 1968 Pacific hurricane season ties the record for having the most active August in terms of tropical storms. It officially started on May 15, 1968, in the eastern Pacific and June 1 in the central Pacific and lasted until November 30, 1968. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.
Hurricane Hernan was fourth and final tropical cyclone to strike Mexico at hurricane intensity during the 1996 Pacific hurricane season. The thirteenth tropical cyclone, eighth named storm, and fifth hurricane of the season, Hernan developed as a tropical depression from a tropical wave to the south of Mexico on September 30. The depression quickly strengthened, and became Tropical Storm Hernan later that day. Hernan curved north-northwestward the following day, before eventually turning north-northeastward. Still offshore of the Mexican coast on October 2, Hernan intensified into a hurricane. Six hours later, Hernan attained its peak as an 85 mph (140 km/h) Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale (SSHWS). After weakening somewhat, on 1000 UTC October 3, Hurricane Hernan made landfall near Barra de Navidad, Jalisco, with winds of 75 mph (120 km/h). Only two hours after landfall, Hernan weakened to a tropical storm. By October 4, Tropical Storm Hernan had weakened into a tropical depression, and dissipated over Nayarit on the following day.
Tropical Storm Norman was a tropical cyclone that hit Mexico in September 2000. The sixteenth cyclone and fourteenth named storm of the 2000 Pacific hurricane season, Norman originated in a tropical wave that emerged from the coast of Africa on September 4, and moved westward across the Atlantic Ocean; the wave entered the Pacific on September 16. The disturbance organized into a tropical depression on early on September 20, and later that day the storm reached its peak intensity of 50 mph (80 km/h), and subsequently made landfall to the west of Lázaro Cárdenas, Michoacán. After weakening to a tropical depression over land, the storm re-emerged over open waters, and made a second landfall before dissipating shortly thereafter. The storm produced heavy rain that resulted in flooding and mudslides, killing about nine people.
Hurricane Olaf was a minimal hurricane that impacted Mexico in October 2003. The fifteenth named storm and sixth hurricane of the annual season, Olaf formed from a tropical wave became better organized on October 2 to the south-southeast of Acapulco and developed into a depression the next day. It strengthened into Tropical Storm Olaf six hours after forming. Continued intensification occurred, and Olaf reached its peak strength as a Category 1 hurricane with 75 mph (120 km/h) winds on October 5 and developed a partial eyewall. The storm soon became disorganized and was only a hurricane for six hours, before re-curving towards the Mexican coast. The cyclone made landfall near Manzanillo, Colima, on October 7 and soon dissipated overland. The storm caused severe flooding in the states of Jalisco and Guanajuato. However, no fatalities were reported.
Hurricane Odile was the second of three tropical storms to make landfall in Mexico during the 1984 Pacific hurricane season. The fifteenth named storm and twelfth hurricane of the active season, it developed from a tropical disturbance about 185 miles (298 km) south of Acapulco on September 17. Curving towards the northwest, Odile became a Category 1 hurricane on September 19. The tropical cyclone reached its peak intensity with winds of 105 mph (169 km/h) two days later; however, Hurricane Odile began to weaken as moved erratically it encountered less favorable conditions and was downgraded to a tropical storm shortly before making landfall northwest of Zihuatanejo. Over land, the storm rapidly weakened, and dissipated on September 23. The storm caused significant rainfall accumulations of 24.73 inches (628 mm) in Southern Mexico, resulting in severe damage to tourism resorts. Flooding from Odile resulted in the evacuation of 7,000 people, 21 deaths, and the damage of about 900 homes.
During 2022, tropical cyclones formed in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones were named by various weather agencies when they attained maximum sustained winds of 35 knots. During the year, 133 systems formed, of which 87 were named. The strongest storm to form was Typhoon Nanmadol, with minimum pressure of 910 hPa (26.87 inHg). The deadliest tropical cyclone was Tropical Storm Megi, which caused 214 fatalities in the Philippines, while the costliest was Hurricane Ian, which had an estimated damage total of at least $113.1 billion after affecting Trinidad and Tobago, Venezuela, Colombia, the western part of the Greater Antilles and Southeast United States.
During 2023, tropical cyclones formed in seven major bodies of water, commonly known as tropical cyclone basins. They were named by various weather agencies when they attained maximum sustained winds of 35 knots. Throughout the year, a total of 115 systems formed, with 79 of them being named. The most intense storm this year was Typhoon Mawar, which had a minimum pressure of 900 hPa (26.58 inHg). The deadliest tropical cyclone of the year was Storm Daniel, which killed at least 10,028 people in Libya, Greece, Turkey, and Bulgaria. Meanwhile, the costliest tropical cyclone was Typhoon Doksuri which caused at least US$28.4 billion worth of damage in China, the Philippines and Taiwan, becoming the costliest on record outside the Atlantic Ocean basin. Among this year's systems, thirty became major tropical cyclones, of which ten intensified into Category 5 tropical cyclones on the Saffir–Simpson scale (SSHWS). This year, for the first time on record, at least one such Category 5 system formed in each tropical cyclone basin: Typhoons Mawar, Saola, and Bolaven in the western Pacific Ocean, Hurricanes Jova and Otis in the eastern Pacific, Hurricane Lee in the Atlantic, Cyclone Mocha in the North Indian Ocean, Cyclone Freddy in the southwest Indian Ocean, Cyclone Ilsa in the Australian region, and Cyclone Kevin in the South Pacific. The accumulated cyclone energy (ACE) index for the 2023, as calculated by Colorado State University (CSU) was 857.4 units, which was above the 1991-2020 mean of 770.2 units.
