The 2003 Pacific hurricane season was the first season to feature no major hurricanes since 1977. The season officially began on May 15, 2003 in the Eastern North Pacific, and on June 1 in the Central ; both ended 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. The season featured 16 tropical storms, 7 of which intensified into 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 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 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.
Hurricane Pauline was one of the deadliest Pacific hurricanes to make landfall in Mexico. The sixteenth tropical storm, eighth hurricane, and seventh major hurricane of the 1997 Pacific hurricane season, Pauline developed out of a tropical wave from Africa on September 16, 1997, moving across South America and into the Pacific Ocean. On October 5, the depression intensified into a tropical storm early the next day and by October 7, Pauline had reached hurricane intensity. It initially moved eastward, then turned northwestward and quickly strengthened to reach peak winds of 135 mph (217 km/h). It paralleled the Mexican coastline a short distance offshore before weakening and making landfall near Puerto Ángel, Oaxaca, on October 9, and dissipated the next day.
Hurricane Stan was the deadliest tropical cyclone of the 2005 Atlantic hurricane season. A relatively weak system that affected areas of Central America and Mexico in early October 2005, Stan was the eighteenth named storm and eleventh hurricane of the 2005 season, having formed from a tropical wave on October 1 after it had moved into the western Caribbean. The depression slowly intensified, and reached tropical storm intensity the following day, before subsequently making its first landfall on the Yucatán Peninsula. While traversing the peninsula, the tropical storm weakened, but was able to re-intensify once it entered the Bay of Campeche. Under favorable conditions for tropical development, Stan attained hurricane strength on October 4, and later reached peak intensity with winds of 80 mph (130 km/h) and a minimum barometric pressure of 977 mbar (28.9 inHg). The hurricane maintained this intensity until landfall in the Mexican state of Veracruz later the same day. Once over the mountainous terrain of Mexico, however, Stan quickly weakened, and dissipated on October 5.
Hurricane Juliette was a powerful Pacific hurricane that struck Mexico in September 2001. A long-lived tropical cyclone, Juliette originated from a tropical wave that exited western Africa, the same wave that earlier spawned Atlantic Tropical Depression Nine near Nicaragua on September 19. Two days later, a new tropical depression developed offshore Guatemala, which became Hurricane Juliette by September 22 as it rapidly intensified off western Mexico. On September 24 it strengthened into a Category 4 hurricane on the Saffir-Simpson scale, only to weaken due to an eyewall replacement cycle, then re-intensified a day later to attain maximum sustained winds of 230 km/h (145 mph), with a minimum barometric pressure of 923 mbar (27.3 inHg). Juliette weakened as it moved toward the Baja California peninsula, producing hurricane-force winds and torrential rainfall across Baja California Sur. On September 30 after the hurricane had weakened, Juliette made landfall near San Carlos as a minimal tropical storm. After drifting across the Gulf of California, Juliette dissipated on October 3.
Tropical Storm Barbara was the first tropical cyclone to make landfall during the 2007 Pacific hurricane season. The second storm of the season, Barbara developed from a small low-pressure area on May 29 about 235 miles (380 km) southeast of Acapulco, Mexico. The system drifted southward before turning to a steadily eastward motion, and quickly intensified into a tropical storm. Increased wind shear weakened Barbara, though it re-organized to attain peak winds of 50 mph (80 km/h) before moving ashore just west of the border of Mexico and Guatemala. It rapidly weakened over land, and on June 2 the National Hurricane Center discontinued advisories on the storm. Despite expectations that the storm would attain hurricane status, Barbara moved ashore as a small, weak tropical storm. It produced locally heavy rainfall and gusty winds, and in most locations damage was minor. However, in southern Mexico, the rainfall destroyed large areas of cropland, with crop damage totaling 200 million pesos. In El Salvador, four people were killed by storm-induced floods.
Hurricane Hernan was the 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.
Hurricane Bridget of June 1971 was one of the worst hurricanes to strike the Mexican city of Acapulco. It formed on June 14 as a tropical depression, which is a minimal tropical cyclone with winds less than gale force. However, it was soon upgraded to a tropical storm, and Bridget steadily intensified to become a hurricane on June 15. After peaking at Category 2 intensity, it weakened to a tropical storm on June 17, then made landfall in Mexico. Hours later, however, it turned offshore as a tropical depression. Bridget dissipated on June 20 after leaving heavy damage and 17 deaths in the Acapulco area.
The 2009 Pacific hurricane season was the most active Pacific hurricane season since 1997. The season officially started 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 Eastern Pacific tropical cyclone basin; however, tropical cyclone formation is possible at any time of the year. The first system of the season, Tropical Depression One-E, developed on June 18, and the last, Hurricane Neki, dissipated on October 27, keeping activity well within the bounds of the season.
Hurricane Barbara was the easternmost landfalling Pacific hurricane on record. As the first hurricane of the 2013 Pacific hurricane season, Barbara developed from a low-pressure area while located southeast of Mexico on May 28. It headed slowly north-northeastward and strengthened into a tropical storm early on the following day. After recurving to the northeast, Barbara intensified into a Category 1 hurricane on May 29 and made landfall in Chiapas at peak intensity with winds of 80 mph (130 km/h) and a barometric pressure estimated at 983 mbar. When the hurricane made landfall, it was the second earliest landfalling hurricane in the basin since reliable records began in 1966. Barbara then moved across the Isthmus of Tehuantepec and dissipated within the mountainous terrain of Sierra Madre de Chiapas on May 30.
Tropical Storm Carlos was the first of five tropical cyclones to make landfall during the 2003 Pacific hurricane season. It formed on June 26 from a tropical wave to the south of Mexico. It quickly strengthened as it approached the coast, and early on June 27 Carlos moved ashore in Oaxaca with winds of 65 mph (105 km/h). The storm rapidly deteriorated to a remnant low, which persisted until dissipating on June 29. Carlos brought heavy rainfall to portions of southern Mexico, peaking at 337 mm (13.3 in) in two locations in Guerrero. Throughout its path, the storm damaged about 30,000 houses, with a monetary damage total of 86.7 million pesos. At least nine people were killed throughout the country, seven due to mudslides and two from river flooding; there was also a report of two missing fishermen.
Tropical Storm Hermine caused significant flooding in Mexico during September 1980. The eleventh tropical cyclone and eight named storm of the 1980 Atlantic hurricane season, Hermine developed from a tropical wave that emerged into the Atlantic from the west coast of Africa on September 11. After uneventfully crossing the Atlantic Ocean, the system developed a well-defined circulation while in the Caribbean Sea on September 20 and was then classified as a tropical depression. After becoming a tropical cyclone, the depression steadily strengthened as it tracked nearly due westward. By September 21, it strengthened into Tropical Storm Hermine and brushed the northern coast of Honduras shortly thereafter. It nearly became a hurricane before it made landfall in Belize on September 22. After weakening over the Yucatan Peninsula, Hermine restrengthened to near-hurricane status again over the Gulf of Mexico before making landfall in the Mexican state of Veracruz. Hermine steadily weakened inland and eventually dissipated on September 26.
Hurricane Carlotta was the easternmost tropical cyclone in the Eastern Pacific to make landfall at hurricane intensity since 1966. The third tropical cyclone and third named storm of the 2012 Pacific hurricane season, Carlotta developed slowly into a tropical depression from a tropical wave southwest of Central America on June 14. It moved generally west-northwestward and by the following day, strengthened into tropical storm strength. Thereafter, gradual intensification occurred and the storm reached hurricane strength on June 15. Rapid intensification ensued further, as Carlotta peaked as a 110 mph (180 km/h) Category 2 hurricane on the same day. At 0100 UTC the following day, Carlotta made landfall near Puerto Escondido, the easternmost landfalling Pacific hurricane in recorded history at the time. The next day the storm began to weaken as it moved onshore Southwestern Mexico. Carlotta continued to weaken rapidly, eventually dissipating on June 16.
Tropical Storm Harvey was the final tropical cyclone in a record-breaking string of eight consecutive storms that failed to attain hurricane intensity. The eighth tropical cyclone and eighth named storm of the 2011 Atlantic hurricane season, Harvey developed from a tropical wave in the western Caribbean Sea on August 19. It moved over warm waters in the vicinity of Central America. Later on August 19, the system strengthened into Tropical Storm Harvey while just offshore Honduras. Additional organization occurred and Harvey attained its peak intensity of 65 mph (100 km/h) prior to coming ashore Belize on August 20. Harvey weakened to a tropical depression on August 21, but re-intensified to a tropical storm after emerging into the Bay of Campeche. Early on August 22, it made landfall in Veracruz, then weakened and dissipated several hours later.
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, as 19 named storms, 8 hurricanes, and 2 major hurricanes formed 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.
Hurricane Nana was a small, short-lived tropical cyclone that caused relatively minor damage in Belize and Mexico in early September 2020. The sixteenth tropical cyclone, fourteenth named storm, and fifth hurricane of the record-breaking 2020 Atlantic hurricane season, Nana originated from a tropical wave that moved off the coast of West Africa on August 23. The system progressed westward with little development for the next week before crossing into the Caribbean Sea. The wave gradually developed organized convection and a defined surface low on September 1, signifying the formation of Tropical Storm Nana as it approached Jamaica. Persistent wind shear stifled development of the storm, though following repeated bursts of deep convection, it intensified into a minimal hurricane on September 3. Nana attained peak winds of 75 mph (121 km/h) and a minimum pressure of 994 mbar shortly before striking Belize. Once onshore, the hurricane rapidly degraded and its surface low dissipated over Guatemala on September 4. The mid-level remnants of Nana later reorganized over the Gulf of Tehuantepec and became Tropical Storm Julio.
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.
Hurricane Rick was a Category 2 Pacific hurricane that struck the southwestern coast of Mexico in late October 2021. Rick was the overall seventeenth named system and the eighth hurricane of the 2021 Pacific hurricane season, as well as the fifth named storm and fourth hurricane to make landfall along the Pacific coast of Mexico in 2021.
Tropical Storm Lester was a short-lived tropical cyclone that caused severe rainfall and flash flooding in southern Mexico in September 2022. The thirteenth named storm of the 2022 Pacific hurricane season, Lester developed from an area of disturbed weather that formed offshore the Pacific Coast of Mexico on September 13. The disturbance spawned an area of low pressure two days later, which quickly organized into a tropical depression at 18:00 UTC on September 15. Moving slowly northwestward, the depression strengthened into Tropical Storm Lester the following morning. Despite being located over very warm sea surface temperatures and in a moist environment, Lester was unable to intensify further and remained a minimal tropical storm as it slowly approached the coast of Mexico, due to moderately strong wind shear. Lester made landfall near Punta Maldonado in extreme southwestern Guerrero as a tropical depression around 12:00 UTC on September 17. The cyclone quickly dissipated over the rough terrain of Mexico later that day.
