The 1995 Atlantic hurricane season was a very active Atlantic hurricane season, and is considered to be the start of an ongoing era of high-activity tropical cyclone formation. The season produced twenty-one tropical cyclones, nineteen named storms, as well as eleven hurricanes and five major hurricanes. The season officially began on June 1 and ended on November 30, dates which conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The first tropical cyclone, Hurricane Allison, developed on June 2, while the season's final storm, Hurricane Tanya, transitioned into an extratropical cyclone on November 1. The very active Atlantic hurricane activity in 1995 was caused by La Niña conditions, which also influenced an inactive Pacific hurricane season. It was tied with 1887 Atlantic hurricane season with 19 named storms, which was later equalled by the 2010, 2011, and 2012 seasons.
The 1992 Atlantic hurricane season was a significantly below average season for overall tropical or subtropical cyclones as only ten formed. Six of them became named tropical storms, and four of those became hurricanes; one hurricane became a major hurricane. The season was also near-average in terms of accumulated cyclone energy. The season officially started on June 1 and officially ended on November 30. However, tropical cyclogenesis is possible at any time of the year, as demonstrated by formation in April of an unnamed subtropical storm in the central Atlantic.
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 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 1993 Pacific hurricane season included more than double the average number of major hurricanes – Category 3 or stronger cyclones on the Saffir–Simpson scale. This activity was the result of an El Niño event, which is the main factor contributing to above-average activity across the Pacific basin. The season featured 15 named storms, 11 hurricanes, and 9 major hurricanes. While the number of named storms was near the long-term average, the number of hurricanes was above the average of 8, and the number of major hurricanes far exceeded the long-term average of 4. Seasonal activity began on May 17 and ended on November 8, within the confines of a traditional hurricane season which begins on May 15 in the East Pacific and June 1 in the Central Pacific. The season ends on November 30 in both basins. These dates conventionally delimit the period during each year when most tropical cyclones form.
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.
Tropical Storm Helene was a long-lived tropical cyclone that oscillated for ten days between a tropical wave and a 70 mph (110 km/h) tropical storm. It was the twelfth tropical cyclone and eighth tropical storm of the 2000 Atlantic hurricane season, forming on September 15 east of the Windward Islands. After degenerating into a tropical wave, the system produced flooding and mudslides in Puerto Rico. It reformed into a tropical depression on September 19 south of Cuba, and crossed the western portion of the island the next day while on the verge of dissipation. However, it intensified into a tropical storm in the Gulf of Mexico, reaching its peak intensity while approaching the northern Gulf Coast.
Hurricane Lester was a small but powerful tropical cyclone that caused heavy flooding in Central America and southern Mexico in October 1998. Lester was the fifteenth tropical cyclone, twelfth named storm and eighth hurricane of the 1998 Pacific hurricane season. Lester originated from a tropical wave that emerged off the coast of Africa on September 29. Under favorable conditions, the storm was classified as a tropical depression on October 15. The depression was upgraded to a tropical storm later that day and a hurricane on October 16. After undergoing fluctuations in intensity, Lester reached peak winds of 115 mph (185 km/h), a Category 3 hurricane on the Saffir-Simpson Hurricane Scale. After several days, it degenerated into a tropical storm on October 26, and dissipated shortly after. The hurricane made its closest approach to land on October 28, producing moderate winds and heavy rainfall. A mudslide triggered by the precipitation killed two children, although damage is unknown.
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.
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.
Hurricane Rosa was the only Pacific hurricane to make landfall during the above-average 1994 Pacific hurricane season. It killed at least 4 people in Mexico. Moisture from the hurricane was a factor in widespread flooding in the U.S. state of Texas that killed 22 people and caused hundreds of millions of dollars in damage in October 1994. The pre-Rosa tropical depression formed on October 8 before degenerating the next day. It reformed on October 10 and steadily strengthened as it approached Mexico. Ultimately peaking as a Category 2 hurricane on the Saffir-Simpson Hurricane Scale right before landfall, Rosa was the final hurricane, nineteenth tropical storm, and second-last tropical cyclone of the 1994 Pacific hurricane season.
Hurricane Florence was a strong, late season hurricane that remained out over the open waters of the Atlantic Ocean for nearly a week, before being absorbed into a large extratropical cyclone. With peak winds of 110 mph (180 km/h) and a minimum pressure of 972 mbar, Florence was the strongest storm of the 1994 Atlantic hurricane season. Florence developed out of an area of low pressure associated with a stalled frontal system located 1,150 mi (1,850 km) east-southeast of Bermuda in late October. The system gradually became better organized and was classified a subtropical depression on November 2. The storm intensified into a subtropical storm shortly thereafter before weakening into a tropical depression on the next day.
The 1994 Atlantic hurricane season was the final season in the most recent negative Atlantic multidecadal oscillation period of tropical cyclone formation within the basin. The season produced seven named tropical cyclones and three hurricanes, a total well below the seasonal average. The season officially started on June 1 and ended on November 30, dates which conventionally limit the period each year when most tropical cyclones tend to form in the Atlantic Ocean. The first tropical cyclone, Tropical Storm Alberto, developed on June 30, while the last storm, Hurricane Gordon, dissipated on November 21. The season was unusual in that it produced no major hurricanes, which are those of Category 3 status or higher on the Saffir–Simpson hurricane scale. The most intense hurricane, Hurricane Florence, peaked as a Category 2 storm with winds of 110 mph (180 km/h).
The 1994 Atlantic hurricane season was a below-average Atlantic hurricane season that produced seven named tropical cyclones. The season officially began on June 1 and ended on November 30, dates which conventionally limit the period of each year when tropical cyclones tend to form in the Atlantic. The first named storm, Tropical Storm Alberto, formed on June 30. The last storm of the season, Hurricane Gordon, dissipated on November 21. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation during the season. The timeline also includes information which was not operationally released, such as post-storm reviews by the National Hurricane Center.
The meteorological history of Hurricane Luis spanned sixteen days between August 27 to September 11, 1995. The storm originated from an area of low pressure associated with a tropical wave on August 26. The following day, the low became sufficiently organized to be classified as a tropical depression, while tracking general westward. By August 29, the depression intensified into a tropical storm and was given the name Luis by the National Hurricane Center. Luis attained hurricane status the following day as an eye began to develop. On September 1 the cyclone intensified into a major hurricane—a storm with winds of 111 mph (179 km/h) or higher—and further strengthened to a Category 4 hurricane later that day.
The meteorological history of Hurricane Georges spanned seventeen days from September 15 to October 1, 1998. Hurricane Georges began as a tropical wave that moved off the coast of Africa during mid-September 1998. Tracking westward, the wave spawned an area of low pressure two days later, which quickly strengthened into a tropical depression. On September 16, the depression was upgraded to Tropical Storm Georges, and to Hurricane Georges the next day. Over the next few days, an eye developed and deep Atmospheric convection persisted around it. Strong outflow and warm sea surface temperatures allowed the storm to intensify as it tracked towards the west-northwest. The storm reached its peak intensity on September 20 with winds of 155 mph (250 km/h), just below Category 5 status on the Saffir–Simpson hurricane scale, and a barometric pressure of 937 mbar.
Hurricane Hilary was a Category 3 hurricane during the 1993 Pacific hurricane season that brought significant rainfall to the Sonoran Desert region of Mexico and the United States in August of that year. Additionally, its remnants in part caused significant flooding in the Midwestern United States. A westward moving tropical depression gradually developed on August 17 south of the Mexican coast, attaining hurricane status two days later. The storm further intensified into a Category 3 hurricane, attaining peak winds of 120 mph (195 km/h). By August 23, the hurricane nearly stalled while interacting with Tropical Storm Irwin. Executing a small counter-clockwise loop, Hilary degraded to tropical storm intensity and took a northerly track for the remainder of its existence. The storm made two landfalls in Mexico, one in Baja California Sur on August 25 and one in Sonora the following day. Tropical cyclone warnings and watches were issued for much of the southern Mexican coastline; however, they were later discontinued when the threat ended, but were issued again when the system posed a threat to the Baja California Peninsula. Hilary dropped in excess of 5 in (130 mm) rain along its path in some areas, and flash flooding in California and Iowa.
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.
