The 1967 Atlantic hurricane season was an active Atlantic hurricane season overall, producing 13 nameable storms, of which 6 strengthened into hurricanes. The season officially began on June 1, 1967, and lasted until November 30, 1967. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in the Atlantic Ocean. The season's first system, Tropical Depression One, formed on June 10, and the last, Tropical Storm Heidi, lost tropical characteristics on November 2.
The 1991 Atlantic hurricane season was the first season since 1984 in which no hurricanes developed from tropical waves, which are the source for most North Atlantic tropical cyclones. The hurricane season officially began on June 1, and ended on November 30. It was the least active in four years due to higher than usual wind shear across the Atlantic Ocean. The first storm, Ana, developed on July 2 off the southeast United States and dissipated without causing significant effects. Two other tropical storms in the season – Danny and Erika – did not significantly affect land. Danny dissipated east of the Lesser Antilles, and Erika passed through the Azores before becoming extratropical. In addition, there were four non-developing tropical depressions. The second depression of the season struck Mexico with significant accompanying rains.
The 2001 Pacific hurricane season was a relatively near-average Pacific hurricane season which produced sixteen named storms, though most were rather weak and short-lived including one unnamed tropical storm which was operationally recognized as a tropical depression, the first such occurrence since 1996. 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 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 1995 Pacific hurricane season was the least active Pacific hurricane season since 1979, and marked the beginning of a multi-decade period of low activity in the basin. Of the eleven tropical cyclones that formed during the season, four affected land, with the most notable storm of the season being Hurricane Ismael, which killed at least 116 people in Mexico. The strongest hurricane in the season was Hurricane Juliette, which reached peak winds of 150 mph (240 km/h), but did not significantly affect land. Hurricane Adolph was an early-season Category 4 hurricane. Hurricane Henriette brushed the Baja California Peninsula in early September.
The 1994 Pacific hurricane season was the final season of the eastern north Pacific's consecutive active hurricane seasons that started in 1982. The season officially started on May 15, 1994, in the eastern Pacific, and on June 1, 1994, in the central Pacific, and lasted until November 30, 1994. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone formed on June 18, while the last system dissipated on October 26. This season, twenty-two tropical cyclones formed in the north Pacific Ocean east of the dateline, with all but two becoming tropical storms or hurricanes. A total of 10 hurricanes occurred, including five major hurricanes. The above average activity in 1994 was attributed to the formation of the 1994–95 El Niño.
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. However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the development of Hurricane Ekeka on January 28, and Tropical Storm Hali two months later.
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 1985 Pacific hurricane season is the third-most active Pacific hurricane season on record. It officially started on May 15, 1985, in the eastern Pacific, and on June 1, 1985, in the central Pacific, and lasted until November 30, 1985. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. At the time, the 1985 season was the most active on record in the eastern north Pacific, with 28 tropical cyclones forming. Of those, 24 were named, 13 reached hurricane intensity, and 8 became major hurricanes by attaining Category 3 status or higher on the Saffir–Simpson scale. At that time, the 24 named storms was a record; however, this record was broken seven years later in 1992, and was therefore recognized as the second busiest season within the basin, until it was surpassed exactly thirty years later by the 2015 season.
Hurricane Javier was a powerful tropical cyclone whose remnants brought above-average rainfall totals across the western United States in September 2004. Javier was the tenth named storm, the sixth hurricane and the final major hurricane of the 2004 Pacific hurricane season. Javier was also the strongest hurricane of the 2004 season, with 150 mph (240 km/h) winds and a central pressure of 930 millibars. However, because of high wind shear in the East Pacific, Javier weakened rapidly before making landfall in Baja California as a tropical depression. The remnants of the storm then continued moving northeast through the Southwestern United States. Javier caused no direct fatalities, and the damage in Mexico and the United States was minimal.
Tropical Storm Kiko was a strong tropical storm that capsized a boat off the western coast of Mexico, killing at least 15 people. The 15th and final tropical cyclone of the 2007 Pacific hurricane season, Kiko developed out of a tropical wave that formed off the coast of Africa on September 26 and traversed the Atlantic. The wave crossed over Central America and entered the Pacific Ocean on October 8, where it spawned Tropical Depression 15-E on October 15. The depression drifted to the south over the next day before briefly being declared Tropical Storm Kiko. It subsequently weakened into a tropical depression, but later reattained tropical storm intensity. By October 18, Kiko was forecast to make landfall along the western Mexican coastline as a moderate tropical storm. However, the cyclone turned to the west and reached its peak intensity of 70 mph (110 km/h) on October 20. The tropical storm slowly weakened to a remnant low-pressure area by October 24 and completely dissipated on October 27 without making landfall.
Tropical Storm Elida was a strong tropical storm that killed 6 people offshore Mexico and affected over 1,000 others. The ninth tropical cyclone of the below-average 1996 Pacific hurricane season, Elida's origins was a tropical wave that organized into Tropical Depression Eight-E on August 30. The cyclone paralleled the coast of Mexico and also gradually decelerated. Despite some wind shear, Eight-E strengthened into a tropical storm on September 2 and was named Elida. On September 3 and 4, Elida came close to the southern tip of the Baja California Peninsula at its peak intensity of 994 mbar (29.4 inHg) and winds of 65 mph (105 km/h). The cyclone then drifted into cooler waters, was devoid of deep convection on September 5, and dissipated the next day.
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 Raymond was the strongest tropical cyclone of the 1989 Pacific hurricane season, peaking as a strong Category 4 hurricane on the Saffir–Simpson hurricane scale. Forming out of a tropical wave on September 25, 1989, the tropical depression slowly tracked northwest before becoming nearly stationary the next day. Shortly after, the depression intensified into Tropical Storm Raymond and took a general westward track. Gradually intensifying, Raymond attained hurricane-status on September 28 and attained its peak intensity on September 30, with winds of 145 mph (233 km/h) and a barometric pressure of 935 mbar. Steady weakening then took place and by October 3, Raymond turned northeast towards land. The storm continued to weaken as it accelerated and eventually made landfall on the Baja California Peninsula as a tropical storm late on October 4 and a second landfall in Sonora, Mexico. Shortly after, Raymond weakened to a depression as it tracked inland. The remnants of the system persisted until October 7 when it dissipated over the Central United States.
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 2015 Pacific hurricane season is the second-most active Pacific hurricane season on record, with 26 named storms, only behind the 1992 season. A record-tying 16 of those storms became hurricanes, and a record 11 storms further intensified into major hurricanes throughout the season. The Central Pacific, the portion of the Northeast Pacific Ocean between the International Date Line and the 140th meridian west, had its most active year on record, with 16 tropical cyclones forming in or entering the basin. Moreover, the season was the third-most active season in terms of accumulated cyclone energy, amassing a total of 290 units. The season 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 the Northeast Pacific basin. However, the formation of tropical cyclones is possible at any time of the year. This was shown when a tropical depression formed on December 31. The above-average activity during the season was attributed in part to the very strong 2014–16 El Niño event.
Hurricane Mitch's meteorological history began with its origins over Africa as a tropical wave and lasted until its dissipation as an extratropical cyclone north of the United Kingdom. Tropical Depression Thirteen formed on October 22, 1998, over the southwestern Caribbean Sea from a tropical wave that exited Africa on October 10. It executed a small loop, and while doing so intensified into Tropical Storm Mitch. A weakness in a ridge allowed the storm to track slowly to the north. After becoming disorganized due to wind shear from a nearby upper-level low, Mitch quickly intensified in response to improving conditions which included warm waters and good outflow. It became a hurricane on October 24 and developed an eye. After turning to the west, Mitch rapidly intensified, first into a major hurricane on October 25 and then into a Category 5 on the Saffir-Simpson Hurricane Scale the next day.
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.
