The 2000 Atlantic hurricane season was a fairly active hurricane season, but featured the latest first named storm in a hurricane season since 1992. The hurricane season officially began on June 1, and ended on November 30. It was slightly above average due to a La Niña weather pattern although most of the storms were weak. It was also the only Season to Include 2 storms in Ireland. The first cyclone, Tropical Depression One, developed in the southern Gulf of Mexico on June 7 and dissipated after an uneventful duration. However, it would be almost two months before the first named storm, Alberto, formed near Cape Verde; Alberto also dissipated with no effects on land. Several other tropical cyclones—Tropical Depression Two, Tropical Depression Four, Chris, Ernesto, Nadine, and an unnamed subtropical storm—did not impact land. Five additional storms—Tropical Depression Nine, Florence, Isaac, Joyce, and Leslie—minimally affected land areas.
The 1998 Atlantic hurricane season was one of the most disastrous Atlantic hurricane seasons on record, featuring the highest number of storm-related fatalities in over 218 years and one of the costliest ever at the time. The season had above average activity, due to the dissipation of the El Niño event and transition to La Niña conditions. It officially began on June 1 and ended on November 30, dates which conventionally delimit the period during which most tropical cyclones form in the Atlantic Ocean. The season had a rather slow start, with no tropical cyclones forming in June. The first tropical cyclone, Tropical Storm Alex, developed on July 27, and the season's final storm, Hurricane Nicole, became extratropical on December 1.
The 1992 Atlantic hurricane season was a significantly below average season in which only ten tropical or subtropical cyclones formed. Six became named tropical storms, of which four became hurricanes. Among the four was Hurricane Andrew, a major hurricane, and the costliest Atlantic hurricane on record at the time, surpassing Hugo of 1989. 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. A June tropical depression caused flooding in Cuba and in Florida, where two people were killed. In August, Andrew struck the Bahamas, Florida, and Louisiana. In all, it caused $27.3 billion in damage, mostly in Florida, as well as 65 fatalities. The greatest impact was in South Florida, where the storm made landfall with 1-minute sustained winds of 175 mph (280 km/h).
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 1998 Pacific hurricane season was a fairly average Pacific hurricane season. Despite this, it had nine hurricanes and six major hurricanes, which was well above average. The season officially started on May 15 in the eastern Pacific and on June 1 in the central Pacific, and ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in that region. The first tropical cyclone developed on June 11, about ten days later than the normal start of the season. The final storm of the year, Hurricane Madeline, dissipated on October 20. Storm activity in the Central Pacific Hurricane Center's warning zone was low, with just one tropical depression observed in the region. Two tropical cyclones from the eastern Pacific also entered the central Pacific; the former did so as a hurricane.
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, and the second-costliest Pacific hurricane season in history, behind the 2013 season. The season also produced the second-highest ACE value on record in the basin, only surpassed by the 2018 season. 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 most tropical cyclones form in the northeastern Pacific Ocean. However, these bounds were easily exceeded when Hurricane Ekeka formed on January 28 and again a couple months later with Tropical Storm Hali.
The 2007 Pacific hurricane season was a below-average Pacific hurricane season, featuring one major hurricane. The season officially started on May 15 in the eastern Pacific and on June 1 in the central Pacific, and ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in the region. The first tropical cyclone of the season, Alvin, developed on May 27, while the final system of the year, Kiko, dissipated on October 23. Due to unusually strong wind shear, activity fell short of the long-term average, with a total of 11 named storms, 4 hurricanes, and 1 major hurricane. At the time, 2007 featured the second-lowest value of the Accumulated cyclone energy (ACE) index since reliable records began in 1971. Two tropical cyclones – Cosme and Flossie – crossed into the central Pacific basin during the year, activity below the average of 4 to 5 systems.
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.
Tropical Storm Hermine was the eighth tropical cyclone and named storm of the 1998 Atlantic hurricane season. Hermine developed from a tropical wave that emerged from the west coast of Africa on September 5. The wave moved westward across the Atlantic Ocean, and on entering the northwest Caribbean interacted with other weather systems. The resultant system was declared a tropical depression on September 17 in the central Gulf of Mexico. The storm meandered north slowly, and after being upgraded to a tropical storm made landfall on Louisiana, where it quickly deteriorated into a tropical depression again on September 20.
Hurricane Cosme was a minimal hurricane that threatened Hawaii in mid-July 2007. The sixth tropical cyclone, third named storm and first hurricane of the 2007 Pacific hurricane season, Cosme originated from a tropical wave that emerged off the coast of Africa on June 27 and tracked westward before emerging in the eastern Pacific. A system along the wave organized, and it was classified as a tropical depression on July 14, a tropical storm on July 15, and a hurricane on July 16. Cosme reached peak intensity as a Category 1 hurricane on the Saffir-Simpson Hurricane Scale, but quickly weakened due to cooler waters. Steadily decreasing in strength, the storm was downgraded to a tropical depression before passing to the south of the Hawaiian Islands. The depression crossed into the Central Pacific and degenerated into a remnant low by July 23.
Hurricane Madeline was a costly tropical cyclone whose remnants caused hundreds of millions of dollars in damage in Texas in October 1998. The final tropical cyclone of the 1998 Pacific hurricane season, Madeline originated from a tropical wave that emerged off the coast of Africa on September 25, 1998. The wave traversed the Atlantic Ocean and crossed over Central America on October 5 or 6. Gradually, the system intensified and was classified as a tropical depression on October 16, a tropical storm later that day, and a hurricane on October 17. The storm reached peak winds of 85 mph (137 km/h) about 95 miles (153 km) southwest of San Blas, Nayarit, and after 18 hours it subsequently began to weaken. Although Madeline never made landfall, numerous rainbands affected the Mexican coast causing no known damage or fatalities. The remnant moisture moved north and contributed to flooding in central Texas, which killed 31 people and caused $750 million in damage.
Hurricane Gordon developed during a fourteen-day period along an erratic, persistent, and highly unusual path. The hurricane formed near Panama in the southwestern Caribbean on November 8, 1994. As a tropical depression, it brushed Nicaragua and spent several days in the waters off the country's coast. Strengthening slightly into a tropical storm, Gordon wound its way north into the Greater Antilles. Despite warm waters, persistent wind shear prevented significant strengthening. Executing a slow turn to the north and then the northwest, Gordon made two more landfalls, on eastern Jamaica and eastern Cuba, while delivering tremendous rains to western Hispaniola.
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.
Tropical Storm Odile was a late season tropical storm that formed during the 2008 Pacific hurricane season and affected parts of southern Mexico. A tropical depression formed on October 8, and became Tropical Storm Odile 18 hours later. The storm paralleled the south coast of Mexico, with the center located only several miles offshore. After peaking in intensity, increasing southeasterly vertical wind shear induced a trend of rapid weakening on the storm. Correspondingly, Odile was downgraded to a tropical depression early on 12 October, subsequently degenerating into a remnant low about 55 mi (85 km) south of Manzanillo, Colima. From thereon, the low proceeded slowly south-southwestward before dissipating on October 13. Since Odile stayed at sea, its effects along coastlines were limited. The most notable damages were caused by flooding along the southern coast of Mexico, mostly in Chiapas, Oaxaca, Guerrero and Michoacán. The exact amount of damage, however, remains unknown, and no fatalities were reported as a result of the storm.
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. Despite the below average activity, the season was very deadly, with almost 97% of deaths occurring during Hurricane Gordon, a devastating late-season tropical cyclone that severely impacted the Caribbean Sea, the Greater Antilles and the United States, and one of the longest-lived Atlantic hurricanes on record at the time. The season produced seven named tropical cyclones and three hurricanes, a total below the seasonal average. The season officially started on June 1 and ended on November 30, dates which conventionally limit the period during which most tropical cyclones 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). Aside from Chris, Florence, and Gordon, none of the storms exceeded tropical storm intensity.
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 Ernesto was a Category 2 hurricane and a damaging tropical cyclone that affected several Caribbean Islands and areas of Central America during August 2012. The fifth named storm and second hurricane of the 2012 Atlantic hurricane season, Ernesto originated from a tropical wave that emerged off the west coast of Africa in late July. Moving westward, the system developed into a tropical depression in the central Atlantic, and further into a tropical storm prior to entering the Caribbean Sea. The system encountered high wind shear south of Jamaica but subsequently reached its peak intensity as a Category 2 hurricane as it made landfall on the Yucatán Peninsula. Ernesto briefly emerged in the Bay of Campeche as a strong tropical storm before dissipating over the mountainous terrain of Mexico. The remnant circulation emerged in the eastern Pacific basin, contributing to the formation of Tropical Storm Hector.
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.
