The 2003 Pacific hurricane season was the first season to feature no major hurricanes – storms of Category 3 intensity or higher on the Saffir–Simpson hurricane wind scale (SSHWS) – since 1977. The dates conventionally delimiting the period when most tropical cyclones form in the Pacific Ocean are May 15 in the Eastern Pacific Ocean and June 1 in the Central Pacific, with both seasons ending on November 30. The 2003 season featured 16 tropical storms between May 19 and October 26; 7 of these became hurricanes, which was then considered an average season. Damage across the basin reached US$129 million, and 23 people were killed by the storms.
The 2008 Pacific hurricane season was a near-average Pacific hurricane season which featured seventeen named storms, though most were rather weak and short-lived. Only seven hurricanes formed and two major hurricanes. This season was also the first since 1996 to have no cyclones cross into the central Pacific. The season officially began on May 15 in the eastern Pacific and on June 1 in the central Pacific. It ended in both regions on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclone formation occurs in these regions of the Pacific. This season, the first system, Tropical Storm Alma, formed on May 29, and the last, Tropical Storm Polo, dissipated on November 5.
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.
The 2012 Pacific hurricane season was a moderately active Pacific hurricane season that saw an unusually high number of tropical cyclones pass west of the Baja California Peninsula. The season officially began on May 15 in the eastern Pacific Ocean, and on June 1 in the central Pacific (from 140°W to the International Date Line, north of the equator; 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, the formation of tropical cyclones is possible at any time of the year. This season's first system, Tropical Storm Aletta, formed on May 14, and the last, Tropical Storm Rosa, dissipated on November 3.
Tropical Storm Lowell was a moderate tropical storm that developed during the 2008 Pacific hurricane season. The fourteenth tropical cyclone and thirteen named storm of the season, Lowell formed out of a western side of a trough on September 6. It quickly intensified into Tropical Storm Lowell, peaking as a moderate tropical storm. It pass directly over Socorro Island and began a weakening trend. It weakened into depression before landfall in Baja California Sur and dissipated before striking Sonora. It later joined with a frontal boundary and Hurricane Ike which caused severe damage as far inland as Chicago. In all, the storm had caused 6 deaths and $15.5 million damage.
Tropical Depression One-E was the earliest tropical cyclone in the calendar year to impact the Mexican state of Sinaloa ever recorded. The first system of the 2009 Pacific hurricane season, One-E formed out of an area of disturbed weather on June 18, 2009, and initially tracked slowly northwards. Throughout the day, convection developed around the center of circulation and the system was anticipated to become a tropical storm. Late on June 18, the National Hurricane Center noted that the system was on the verge of becoming a tropical storm; it would have been named Andres had this occurred. However, the following day, strong wind shear caused the depression to rapidly degenerate into a trough of low pressure before dissipating off the coast of Sinaloa.
Tropical Depression Sixteen-E was the final tropical cyclone of the 2004 Pacific hurricane season. The storm developed out of a tropical wave that moved off the western coast of Africa on October 8. The wave crossed the Atlantic Ocean and entered the eastern Pacific on October 18. The system began to gradually organize, and on October 25 it was classified as a tropical depression. The storm did not significantly intensify, as wind shear prevented it from attaining tropical storm status. The short-lived depression moved northward, and made landfall in Mexico on October 26. Quickly deteriorating, the system dissipated shortly thereafter, although its remnants persisted for a couple more days. The depression had no major effects on land. However, it produced heavy rainfall in parts of Mexico, and the remnants triggered thunderstorms over the southwestern United States.
The 2013 Pacific hurricane season was the first to see twenty named storms since 2009 but also had the ninth fewest ACE units on record, as many of the storms were weak and short-lived. The season officially began on May 15 in the Eastern Pacific and started on June 1 in the Central Pacific; both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form east of the International Dateline in the North Pacific basin. The first cyclone, Tropical Storm Alvin, formed on May 15, and the last, Tropical Storm Sonia, dissipated on November 4.
Tropical Storm Beatriz was a short-lived tropical storm that made landfall in the Mexican state of Oaxaca in June 2017. The second named storm of the 2017 Pacific hurricane season, Beatriz developed from a tropical wave which had exited the coast of West Africa on May 18 and crossed Central America, and was designated as Tropical Depression Two-E on May 31. Shortly after being upgraded to a tropical storm, Beatriz made landfall near Puerto Angel, Mexico on the evening of June 1. It subsequently weakened into a tropical depression as it moved ashore, dissipating quickly afterwards.
The 2018 Pacific hurricane season was one of the most active Pacific hurricane seasons on record, producing the highest accumulated cyclone energy value on record in the basin. The season had the fourth-highest number of named storms – 23, tied with 1982. The season also featured eight landfalls, six of which occurred in Mexico. The season officially began 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 the Pacific basin. However, tropical cyclone formation is possible at any time of the year, as illustrated when the first tropical depression formed on May 10, five days prior to the official start of the season.
The 2019 Pacific hurricane season was a near average season which produced nineteen named storms, though most 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 2021 Pacific hurricane season was a moderately active Pacific hurricane season, with above-average activity in terms of number of named storms, but below-average activity in terms of major hurricanes, with 19 named storms, 8 hurricanes, and 2 major hurricanes forming in all. It also had a near-normal accumulated cyclone energy (ACE). The season officially began on May 15, 2021 in the Eastern Pacific Ocean, and on June 1, 2021, in the Central Pacific in the Northern Hemisphere. The season ended in both regions on November 30, 2021. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year, as illustrated by the formation of Tropical Storm Andres on May 9, which was the earliest forming tropical storm on record in the Eastern Pacific. Conversely, 2021 was the second consecutive season in which no tropical cyclones formed in the Central Pacific.
The 2022 Pacific hurricane season was a fairly active Pacific hurricane season, with nineteen named storms, ten hurricanes, and four major hurricanes forming. Also, it was the third consecutive season in which no tropical cyclones formed in the Central Pacific Ocean. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; 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.
Hurricane Douglas was a strong tropical cyclone that became the closest passing Pacific hurricane to the island of Oahu on record, surpassing the previous record held by Hurricane Dot in 1959. The eighth tropical cyclone, fourth named storm, first hurricane, and first major hurricane of the slightly below-average 2020 Pacific hurricane season, Douglas originated from a tropical wave which entered the basin in mid-July. Located in favorable conditions, the wave began to organize on July 19. It became a tropical depression on July 20 and a tropical storm the following day. After leveling off as a strong tropical storm due to dry air, Douglas began rapid intensification on July 23, becoming the season's first major hurricane the following day and peaking as a Category 4 hurricane. After moving into the Central Pacific basin, Douglas slowly weakened as it approached Hawaii. The storm later passed north of the main islands as a Category 1 hurricane, passing dangerously close to Oahu and Kauai, causing minimal damage, and resulting in no deaths or injuries. Douglas weakened to tropical storm status on July 28, as it moved away from Hawaii, before degenerating into a remnant low on July 29 and dissipating on the next day.
Hurricane Genevieve was a strong tropical cyclone that almost made landfall on the Baja California Peninsula in August 2020. The twelfth tropical cyclone, seventh named storm, third hurricane, and second major hurricane of the 2020 Pacific hurricane season, Genevieve formed from a tropical wave that the National Hurricane Center (NHC) first started monitoring on August 10. The wave merged with a trough of low pressure on August 13, and favorable conditions allowed the wave to intensify into Tropical Depression Twelve-E at 15:00 UTC. Just six hours later, the depression became a tropical storm and was given the name Genevieve. Genevieve quickly became a hurricane by August 17, and Genevieve began explosive intensification the next day. By 12:00 UTC on August 18, Genevieve reached its peak intensity as a Category 4 hurricane, with maximum 1-minute sustained winds of 130 mph and a minimum central pressure of 950 millibars (28 inHg). Genevieve began to weaken on the next day, possibly due to cooler waters caused by Hurricane Elida earlier that month. Genevieve weakened below tropical storm status around 18:00 UTC on August 20, as it passed close to Baja California Sur. Soon afterward, Genevieve began to lose its deep convection and became a post-tropical cyclone by 21:00 UTC on August 21, eventually dissipating off the coast of Southern California late on August 24.
Tropical Storm Beta was a tropical cyclone that brought heavy rainfall, flooding, and severe weather to the Southeastern United States in September 2020. The twenty-third tropical depression and twenty-third named storm of the record-breaking 2020 Atlantic hurricane season, Beta originally formed from a trough of low pressure that developed in the northeastern Gulf of Mexico on September 10. The low moved slowly southwestward, with development hampered initially by the development of nearby Hurricane Sally. After Sally moved inland over the Southeastern United States and weakened, the disturbance became nearly stationary in the southwestern Gulf, where it began to organize. By September 16, the storm had gained a low-level circulation center and had enough organization to be designated as Tropical Depression Twenty-Two. The system held its intensity for a day due to the influence of strong wind shear and dry air, before eventually attaining tropical storm strength. It slowly moved northward and intensified to a mid-range tropical storm before dry air and wind shear halted its intensification. Beta then became nearly stationary on September 19, before starting to move west towards the Texas coast the next day, weakening as it approached. On September 21, Beta made landfall near Matagorda Peninsula, Texas as a minimal tropical storm. It subsequently weakened to a tropical depression the next day before becoming post-tropical early on September 23. Its remnants moved northeastward, before the center elongated and merged with a cold front early on September 25.
Hurricane Gamma was a Category 1 hurricane that brought heavy rains, flooding, and landslides to the Yucatán Peninsula in early October 2020. The twenty-fifth depression, twenty-fourth named storm and ninth hurricane of the extremely active 2020 Atlantic hurricane season, Gamma developed from a vigorous tropical wave that had been monitored as it was entering the Eastern Caribbean on September 29. The wave moved westward and slowed down as it moved into the Western Caribbean, where it began to interact with a dissipating cold front. A low formed within the disturbance on October 1 and the next day, it organized into a tropical depression. It further organized into Tropical Storm Gamma early the next day. It continued to intensify and made landfall as a minimal hurricane near Tulum, Mexico, on October 3. It weakened over land before reemerging in the Gulf of Mexico. Gamma then briefly restrengthened some before being blasted by high amounts of wind shear, causing it to weaken again. It made a second landfall as a tropical depression in Nichili, Mexico on October 6 before dissipating as it was absorbed by the approaching Hurricane Delta.
Tropical Storm Helene was a moderate tropical storm which affected the southern Caribbean and Central America in mid-August 2012. The seventh tropical depression and eighth named storm of the 2012 Atlantic hurricane season, Helene was monitored as a tropical wave that exited the west coast of the African continent on August 5. It gradually moved westward and became a tropical depression east of the Lesser Antilles four days later. However, unfavorable conditions initially prevented it from developing, which led to its initial degeneration to a remnant low as it traversed the Caribbean Sea.
Tropical Storm Dolores was a strong tropical storm that affected several states in southwestern Mexico in June 2021. The fourth named storm of the 2021 Pacific hurricane season, Dolores developed from a low-pressure area that formed offshore the state of Oaxaca on June 16, 2021. The area steadily developed deep convection and a closed surface circulation, becoming Tropical Depression Four-E around 09:00 UTC on June 18. The depression quickly strengthened to Tropical Storm Dolores six hours later. As it gradually approached the coast, Dolores steadily intensified despite its proximity to land. It reached peak intensity at 15:00 UTC on June 19 with maximum sustained winds of 70 mph (115 km/h) and a minimum barometric pressure of 990 millibars (29 inHg), just below hurricane strength. Shortly afterward, Dolores made landfall just northwest of Punta San Telmo, Mexico, near the Colima-Michoacán state border. The storm rapidly weakened as it moved inland and dissipated early on June 20 over Zacatecas. However, the storm's mid-level circulation continued northward, before it dissipated later that day.
Hurricane Nora was a large tropical cyclone that made landfall in southern Mexico, and later went to affect Baja California. The fourteenth named storm and fifth hurricane of the 2021 Pacific hurricane season, the system was first monitored by the National Hurricane Center (NHC) as an area of low pressure near the coast of Mexico. It intensified into Tropical Depression Fourteen-E, but the depression struggled to develop as a result of wind shear. It further intensified to a tropical storm and was named Nora as it tracked west-northwest. It peaked as a Category 1 hurricane with winds of 85 miles per hour (140 km/h) on August 28, before grazing the Mexico coastline and making landfall two separate times, dissipating on August 30. According to the National Hurricane Center's Tropical Cyclone Report, three direct deaths occurred as a result of Nora.
