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 have two of the storms affect 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 1999 Atlantic hurricane season was a fairly active season, mostly due to a persistent La Niña that developed in the latter half of 1998. It had five Category 4 hurricanes – the highest number recorded in a single season in the Atlantic basin, previously tied in 1933 and 1961, and later tied in 2005 and 2020. The season officially began on June 1, and ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first storm, Arlene, formed on June 11 to the southeast of Bermuda. It meandered slowly for a week and caused no impact on land. Other tropical cyclones that did not affect land were Hurricane Cindy, Tropical Storm Emily, and Tropical Depression Twelve. Localized or otherwise minor damage occurred from Hurricanes Bret, Gert, and Jose, and tropical storms Harvey and Katrina.
The 1985 Atlantic hurricane season had six United States landfalling hurricanes, tied with 1886 and 2020 for the highest number on record. The season officially began on June 1 and lasted until November 30. It was an average season, with 11 named storms developing. This was partially attributed to a La Niña – a meteorological phenomenon that produces favorable conditions across the Atlantic basin, such as lower wind shear and higher sea surface temperatures. The first storm, Ana, developed on July 15 near Bermuda and caused minor effects in Canada while transitioning into an extratropical cyclone. Three other tropical cyclones – Claudette, Henri, and Isabel – did not significantly affect land. Claudette developed offshore of the Southeastern United States and brushed Bermuda and the Azores. Henri and Isabel were dissipating as they approached land. However, the precursor of the latter caused a severe flood in Puerto Rico that killed 180 people. Additionally, Tropical Storm Fabian and three tropical depressions did not have any known impact on land.
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 2007 Pacific hurricane season was a well below-average Pacific hurricane season, featuring only 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.
Hurricane Wilma was the most intense tropical cyclone in the Atlantic basin on record in terms of minimum barometric pressure, with an atmospheric pressure of 882 millibars (26.0 inHg). Wilma's destructive journey began in the second week of October 2005. A large area of disturbed weather developed across much of the Caribbean and gradually organized to the southeast of Jamaica. By late on October 15, the system was sufficiently organized for the National Hurricane Center to designate it as Tropical Depression Twenty-Four.
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 2011 Atlantic hurricane season was the second in a group of three very active Atlantic hurricane seasons, each with 19 named storms, tied with 1887, 1995, 2010, and 2012. The above-average activity was mostly due to a La Niña that persisted during the previous year. Of the season's 19 tropical storms, only seven strengthened into hurricanes, and four of those became major hurricanes: Irene, Katia, Ophelia, and Rina. The season officially began on June 1 and ended on November 30, dates which conventionally delimit the period during each year in which most tropical cyclones develop in the Atlantic Ocean. However, the first tropical storm of the season, Arlene, did not develop until nearly a month later. The final system, Tropical Storm Sean, dissipated over the open Atlantic on November 11.
The 2013 Pacific hurricane season was an above average Pacific hurricane season with 21 tropical cyclones forming. Of these, 20 became named storms – 18 in the Eastern Pacific basin, and 2 in the Central Pacific basin. Of the 18 named storms in the east, 9 became hurricanes, with one, Raymond, becoming the season's only major hurricane. In the central, neither named storm became a hurricane. It was also a below-normal season in terms of Accumulated cyclone energy (ACE), as many of its systems 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 development occurs in these North Pacific basins. The first cyclone, Tropical Storm Alvin, formed on May 15, and the last, Tropical Storm Sonia, dissipated on November 4.
The 2014 Pacific hurricane season was one of the busiest and costliest Pacific hurricane seasons since the keeping of reliable records began in 1949. 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 these regions of the Pacific.
The 2012 Atlantic hurricane season was the final year in a string of three consecutive very active seasons since 2010, with 19 tropical storms. The 2012 season was also a costly one in terms of property damage, mostly due to Hurricane Sandy. The season officially began on June 1 and ended on November 30, dates that conventionally delimit the period during each year in which most tropical cyclones form in the Atlantic Ocean. However, Alberto, the first named system of the year, developed on May 19 – the earliest date of formation since Subtropical Storm Andrea in 2007. A second tropical cyclone, Beryl, developed later that month. This was the first occurrence of two pre-season named storms in the Atlantic basin since 1951. It moved ashore in North Florida on May 29 with winds of 65 mph (105 km/h), making it the strongest pre-season storm to make landfall in the Atlantic basin. This season marked the first time since 2009 where no tropical cyclones formed in July. Another record was set by Hurricane Nadine later in the season; the system became the fourth-longest-lived tropical cyclone ever recorded in the Atlantic, with a total duration of 22.25 days. The final storm to form, Tony, dissipated on October 25 – however, Hurricane Sandy, which formed before Tony, became extratropical on October 29.
The 2014 Atlantic hurricane season was a below-average hurricane season in terms of named storms and major hurricanes, though average in terms of number of hurricanes overall. It produced nine tropical cyclones, eight of which became named storms; six storms became hurricanes and two intensified further into major hurricanes. The season officially began on June 1, and ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin. The first storm of the season, Arthur, developed on July 1, while the final storm, Hanna, dissipated on October 28, about a month prior to the end of the season.
Hurricane Adrian was an intense, albeit short-lived early-season Category 4 hurricane that brought heavy rainfall and high waves to Mexico in June 2011 during the 2011 Pacific hurricane season. Adrian originated from an area of disturbed weather which had developed during the course of early June, off the Pacific coast of Mexico. On June 7, it acquired a sufficiently organized structure with deep convection to be classified as a tropical cyclone, and the National Hurricane Center (NHC) designated it as Tropical Depression One-E, the first one of 2011. It further strengthened to be upgraded into a tropical storm later that day. Adrian moved rather slowly; briefly recurving northward after being caught in the steering winds. After steady intensification, it was upgraded into a hurricane on June 9. The storm subsequently entered a phase of rapid intensification, developing a distinct eye with good outflow in all quadrants. Followed by this period of rapid intensification, it obtained sustained winds fast enough to be considered a major hurricane and reached its peak intensity as a category 4 hurricane that evening.
Hurricane Maria was a Category 1 hurricane that made landfall on the island of Newfoundland during September 2011. Originating from a tropical wave over the central Atlantic on September 6, Maria moved toward the west and slowly strengthened. While approaching the northern Leeward Islands, however, the system entered a region of higher vertical wind shear and cooler sea surface temperatures, causing it to degenerate into a low-pressure area. It slowly curved toward the north and northeast around the western periphery of the subtropical ridge, and regained tropical storm status on September 10. Maria further strengthened to attain hurricane status while making its closest approach to Bermuda. The cyclone attained peak winds of 80 mph (130 km/h) on September 16, but weakened thereafter because of an increase in wind shear and cooler sea surface temperatures. Maria made landfall on the southeastern coast of Newfoundland during the afternoon hours of September 16 before becoming absorbed by a frontal system later on that same day.
Hurricane Leslie was an Atlantic tropical cyclone that caused minor damage in Bermuda and Atlantic Canada in September 2012. The twelfth tropical cyclone of the annual hurricane season, Leslie developed from a tropical wave located nearly 1,500 miles (2,400 km) east of the Leeward Islands on August 30. About twelve hours later, it strengthened into Tropical Storm Leslie. Tracking steadily west-northwestward, it slowly intensified due to only marginally favorable conditions. By September 2, the storm curved north-northwestward while located north of the Leeward Islands. Thereafter, a blocking pattern over Atlantic Canada caused Leslie to drift for four days. Late on September 5, Leslie was upgraded to a Category 1 hurricane. However, due to its slow movement, the storm causing upwelling, which decreased sea surface temperatures (SST's), weakening Leslie back to a tropical storm on September 7.
Hurricane Rafael produced minor damage in the northeastern Caribbean Sea in mid-October 2012. The seventeenth named storm and ninth hurricane of the 2012 hurricane season, Rafael originated from a tropical wave roughly 230 mi (370 km) south-southeast of Saint Croix on October 12; because the system already contained tropical storm-force winds, it skipped tropical depression status. Though initially disorganized due to moderate wind shear, a subsequent decrease allowed for shower and thunderstorm activity to develop in earnest by October 14, 2012. While moving north-northwestward the following morning, Rafael intensified into a Category 1 hurricane. A cold front off the East Coast of the United States caused the system to turn northward and eventually northeastward by October 16, 2012, at which time Rafael attained its peak intensity with maximum sustained winds of 90 mph (150 km/h). As the cyclone entered a more stable atmosphere and tracked across increasingly cooler sea surface temperatures, it began extratropical transition, a process the system completed by the following afternoon. However, Rafael's extratropical remnant persisted for another nine days, with the storm looping around a larger extratropical low over the north-central Atlantic, before turning southeastward and then eastward. Rafael's remnant later made landfall on Portugal on October 26, before dissipating later that day.
The 2019 Atlantic hurricane season was the fourth consecutive above-average and damaging season dating back to 2016. The season featured eighteen named storms, however, many storms were weak and short-lived, especially towards the end of the season. Six of those named storms achieved hurricane status, while three intensified into major hurricanes. Two storms became Category 5 hurricanes, marking the fourth consecutive season with at least one Category 5 hurricane, the third consecutive season to feature at least one storm making landfall at Category 5 intensity, and the seventh on record to have multiple tropical cyclones reaching Category 5 strength. The season officially began on June 1 and ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the formation of Subtropical Storm Andrea on May 20, making this the fifth consecutive year in which a tropical or subtropical cyclone developed outside of the official season.
Hurricane Raymond was a category 3 major hurricane which briefly threatened the southwestern coast of Mexico before recurving back out to sea. The seventeenth named storm, eighth hurricane, and only major hurricane of the 2013 Pacific hurricane season, Raymond developed from a tropical wave on October 20 south of Acapulco, Mexico. Within favorable conditions for tropical cyclogenesis, Raymond quickly intensified, attaining tropical storm intensity and later hurricane intensity within a day of cyclogenesis. On October 21, the hurricane reached its peak intensity with winds of 125 mph (205 km/h). A blocking ridge forced the hurricane to the southwest, while at the same time Raymond began to quickly weaken due to wind shear. The following day, the tropical cyclone weakened to tropical storm status. After tracking westward, Raymond reentered more favorable conditions, allowing it to intensify back to hurricane strength on October 27 while curving northward. The hurricane reached a secondary peak intensity with winds of 105 mph (165 km/h) several hours later. Deteriorating atmospheric conditions resulted in Raymond weakening for a final time, and on October 30, the National Hurricane Center (NHC) declared the tropical cyclone to have dissipated.
Hurricane Genevieve, also referred to as Typhoon Genevieve, was the first tropical cyclone to track across all three northern Pacific basins since Hurricane Dora in 1999. Genevieve developed from a tropical wave into the eighth tropical storm of the 2014 Pacific hurricane season well east-southeast of Hawaii on July 25. However, increased vertical wind shear caused it to weaken into a tropical depression by the following day and degenerate into a remnant low on July 28. Late on July 29, the system regenerated into a tropical depression, but it weakened into a remnant low again on July 31, owing to vertical wind shear and dry air.
The 2019 Pacific hurricane season was an above average season which produced nineteen named storms, most of which 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.
