Part of the 2015 Atlantic hurricane season |
Hurricane Kate was the latest hurricane to form in the Atlantic basin since Epsilon in 2005,as well as one of the northernmost November hurricanes on record. The eleventh and final named storm and fourth hurricane of the 2015 Atlantic hurricane season,Kate formed out of a disorganized tropical wave that had moved off the coast of Africa on October 30. Unfavorable conditions prevented it from significantly organizing as it traversed the Atlantic. Once it neared the northern coast of Hispaniola on November 7,it began to become somewhat better organized. The next day it developed into a tropical depression;shortly afterwards it developed into Tropical Storm Kate. Kate moved northwest around an area of high pressure,gradually strengthening. On November 11,it intensified into a hurricane while simultaneously peaking in intensity. Shortly afterwards,it transitioned into an extratropical cyclone.
Kate caused minor impacts in the Bahamas,other than gusty winds and some rain showers as it passed just to the east on November 9. It also caused minor surf along the East Coast of the United States.
On October 30, a poorly-defined tropical wave moved off the coast of Africa with little thunderstorm activity. At this point in the season, tropical waves are uncommon due to increasingly unfavourable conditions, making the origins of Kate "rare, but not unprecedented" as described by the National Hurricane Center (NHC) in its post-season report on the storm. [1] Passing through the eastern Atlantic in unfavourable conditions, the disorganized disturbance failed to organize any further. By November 5, however, as the wave approached the Lesser Antilles, a low-level vorticity split from the wave and traveled to the west-northwest, while the tropical wave headed towards Central America. The new disturbance then turned towards Hispaniola and Puerto Rico, at which point the National Hurricane Center began to monitor the disturbance for possible tropical cyclogenesis. [2] [1] On November 7, convection increased as it passed to the northeast of Hispaniola; however, surface pressures were still relatively high. By early on November 8, showers and convection became more concentrated around the area of low pressure, and there was indications that the disturbance was producing gale-force winds in squally bands that were short-lived. [3] It is estimated that Tropical Depression Twelve formed at around 18:00 UTC, after further organization occurred, while located north of the Turks and Caicos Islands. The depression moved to the west in response to an area of high pressure that was situated to its north. Banding features began to develop along with a defined outflow pattern, and after an Air Force reconnaissance aircraft investigated the system on November 9, the depression was upgraded to Tropical Storm Kate at 15:00 UTC that day. [1]
The overall size of Kate was initially relatively small, with a compact central dense overcast (CDO) extending only 40 miles (64 km) from the center of the storm. Kate continued to move to the west-northwest while steadily strengthening, and later made its closest approach to The Bahamas on November 9 – passing about 15 miles (24 km) from Cat Island. [4] However, observations reported that the circulation of Kate was very small and did not register in some of the operating stations. [1] By the early morning hours of November 10, Kate began to turn to the north in response to a trough that was coming off the East Coast of the United States. [5] Shortly thereafter, Kate strengthened to just below hurricane intensity with winds of 70 mph (110 km/h), and was initially predicted to become a hurricane shortly thereafter before passing over cooler sea surface temperatures, [6] however intensification briefly halted. By 00:00 UTC on November 11, Kate had intensified into a hurricane as it began to accelerate northeast into and become embedded into the mid-latitude westerlies, after a microwave pass revealed banding features had become more defined near the center. [7] [1] This made it the latest-forming hurricane in the Atlantic basin since Hurricane Epsilon in 2005. [8] Shortly afterwards, Kate reached its peak intensity with winds of 85 mph (140 km/h) and a pressure of a 980 millibars (29 inHg) based on continued improvement of its satellite presentation. [1] Afterwards, colder waters and increasing wind shear caused Kate to weaken, and it transitioned into an extratropical cyclone by 00:00 UTC on November 12. The remnants of Kate continued to accelerate over the North Atlantic Ocean for another day before slowing down dramatically and turning eastwards before being absorbed by a larger cyclone on November 13. [1]
The precursor to Kate dropped heavy rainfall on Martinique from November 5 through 7. Up to 192 millimetres (7.6 in) of rainfall fell there, causing dangerous flash flooding on the island. No fatalities were reported. [4]
Still recovering from the destruction of Hurricane Joaquin nearly a month prior, residents were advised on November 8, before Kate had formed, to take more precautions in the event that warnings were issued. New shelters were opened for the expected areas to be impacted by the then-precursor to Kate. [9] Ahead of the storm, on November 9, a tropical storm warning was issued for the northern portions of the Bahamas as Kate was expected to pass fairly close to the island chain. [1] However, effects were not as bad as expected, due to the storm's circulation being very small. Because of this, some islands did not even report tropical storm-force winds as Kate passed to the east. [1] The warnings were later discontinued as the storm moved away from the area.
On November 9, the National Emergency Management Agency (NEMA) announced that they would closely monitor the progress of the tropical storm, after a Level II Activation code was put into effect. [10] NEMA Captain Stephen Russell advised residents that local administrators had been informed of the impending storm, to enforce that local disaster committees were prepared, and to have shelters opened, in case an evacuation needed to be ordered for low-lying areas, partially those near the outskirts of the island. In northern Eleuthera, the Glass Window Bridge was shut down in advance of tropical storm conditions. [10] One of the airline services in the Bahamas, Bahamasair, later stated that a flight from Nassau to San Salvador would be delayed by day to early on November 10 due to the weather conditions. Further changes regarding flights to other areas in the Bahamas were stated as being issued in the case that conditions worsened. [10]
That same day, public schools in Cat Island and San Salvador were closed due to the passing of Kate just to the north, advising students and staff to remain safe. [11] In addition, schools in Eleuthera also closed at noon in advance.[ citation needed ]
Only high surf and some outer bands from Kate impacted Bermuda as it accelerated to the north, which was still recovering from Hurricane Joaquin that had passed just west of the island in early October. No damage or deaths were reported. [4]
By November 16, the remnants of Kate had already begun to affect the United Kingdom, where some damage was reported. [12] [13] In Wales, high winds from the system knocked down numerous trees, and heavy rain caused flash flooding, which covered roadways. [14]
In Ireland, reports indicated that up to 80 millimetres (3.1 in) of rain fell as the cyclone pushed through, which triggered flash floods and shortly after, evacuations. County Donegal reported that a bridge had vanished due to the rising tides. [15] Some people even woke to find their cars destroyed in the flood. Multiple road closures had to be put in place due to the heavy rainfall and floods. Rivers were also reported to have burst their banks, with one river, the River Deel, overflowed and flooded into the city of Crossmolina around 6:30 a.m local time on November 15. [15]
The 2004 Atlantic hurricane season was a very deadly, destructive, and active Atlantic hurricane season, with over 3,200 deaths and more than $61 billion in damage. More than half of the 16 tropical cyclones brushed or struck the United States. Due to the development of a Modoki El Niño – a rare type of El Niño in which unfavorable conditions are produced over the eastern Pacific instead of the Atlantic basin due to warmer sea surface temperatures farther west along the equatorial Pacific – activity was above average. The season officially began on June 1 and ended on November 30, though the season's last storm, Otto, dissipated on December 3, extending the season beyond its traditional boundaries. The first storm, Alex, developed offshore of the Southeastern United States on July 31, one of the latest dates on record to see the formation of the first system in an Atlantic hurricane season. It brushed the Carolinas and the Mid-Atlantic, causing one death and $7.5 million (2004 USD) in damage. Several storms caused only minor damage, including tropical storms Bonnie, Earl, Hermine, and Matthew. In addition, hurricanes Danielle, Karl, and Lisa, Tropical Depression Ten, Subtropical Storm Nicole and Tropical Storm Otto had no effect on land while tropical cyclones. The season was the first to exceed 200 units in accumulated cyclone energy (ACE) since 1995, mostly from Hurricane Ivan, which produced the highest ACE out of any storm this season. Ivan generated the second-highest ACE in the Atlantic, only behind the 1899 San Ciriaco Hurricane.
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 1963 Atlantic hurricane season was a slightly below average season in terms of tropical cyclone formation, with a total of ten nameable storms. Even so, it was also a notoriously deadly and destructive season. The season officially began on June 15, 1963, and lasted until November 15, 1963. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first system, an unnamed tropical storm, developed over the Bahamas on June 1.
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 1970 Atlantic hurricane season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season was fairly average, with 14 named storms forming, of which seven were hurricanes. Two of those seven became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. Also, this was the first season in which reconnaissance aircraft flew into all four quadrants of a tropical cyclone.
The 1975 Atlantic hurricane season was a near average hurricane season with nine named storms forming, of which six became hurricanes. Three of those six became major hurricanes, which are Category 3 or higher systems on the Saffir–Simpson scale. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic Ocean.
The 1946 Atlantic hurricane season resulted in no fatalities in the United States. The season officially began on June 15, 1946, and lasted until November 15, 1946. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the first storm, developed in the Gulf of Mexico on June 13, while the final system dissipated just offshore Florida on November 3. There were seven tropical storms; three of them attained hurricane status, while none intensified into major hurricanes, which are Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. This had not occurred since 1940 and would not again until 1968. Operationally, the fifth tropical storm, which existed near the Azores in early October, was not considered a tropical cyclone but was added to HURDAT in 2014.
The 1942 Atlantic hurricane season was one of seven seasons to feature multiple hurricane landfalls in Texas. The season officially lasted from June 16, 1942, to October 31, 1942. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. A total of 11 tropical storms from 1943 are listed in the Atlantic hurricane database, with two additional tropical depressions. The first system of the year, a tropical depression, developed over the central Gulf of Mexico on June 3, while the last system, the Belize hurricane, dissipated over the Yucatán Peninsula on November 11. After the depression dissipated on June 3, the season remained dormant until the next system developed two months later. In mid-August, a hurricane struck Texas, causing about $790,000 (1942 USD) in damage.
The 1929 Atlantic hurricane season was among the least active Atlantic hurricane seasons on record, with only five tropical cyclones forming. Three of them intensified into a hurricane, with one strengthening further into a major hurricane. The first tropical cyclone of the season developed in the Gulf of Mexico on June 27. Becoming a hurricane on June 28, the storm struck Texas, bringing strong winds to a large area. Three fatalities were reported, while damage was conservatively estimated at $675,000 (1929 USD).
The 1919 Atlantic hurricane season was among the least active hurricane seasons in the Atlantic on record, featuring only five tropical storms. Of those five tropical cyclones, two of them intensified into a hurricane, with one strengthening into a major hurricane Two tropical depressions developed in the month of June, both of which caused negligible damage. A tropical storm in July brought minor damage to Pensacola, Florida, but devastated a fleet of ships. Another two tropical depressions formed in August, the first of which brought rainfall to the Lesser Antilles.
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.
Hurricane Edith brought flooding and wind damage to portions of the Greater and Lesser Antilles. The sixth tropical storm and fifth hurricane of the 1963 season, Edith developed east of the Windward Islands on September 23 from an Intertropical Convergence Zone (ITCZ) disturbance. Initially a tropical depression, it strengthened into Tropical Storm Edith the next day. Shortly thereafter, Edith reached hurricane status. Edith fluctuated between Category 1 and 2 status as it moved west-northwest. Upon reaching Category 2 intensity on September 25, the storm peaked with winds of 100 mph (155 km/h). After striking Saint Lucia on September 25, the storm traversed the eastern Caribbean Sea. Curving north-northwest on September 26, Edith made landfall near La Romana, Dominican Republic, early on the following day as a minimal hurricane. Interaction with land and an upper-level trough caused Edith to weaken to a tropical storm on September 28 and to a tropical depression by the next day. The storm dissipated just east of the Bahamas on September 29.
The 2015 Atlantic hurricane season was the last of three consecutive below average Atlantic hurricane seasons. It produced twelve tropical cyclones, eleven named storms, four hurricanes, and two major hurricanes. The Accumulated Cyclone Energy (ACE) for the season was 68% of the long-term median value. The hurricane season officially began on June 1, 2015, and ended on November 30, 2015. These dates historically describe the period each year when most tropical cyclones form in the North Atlantic basin. However, the first named storm, Ana, developed on May 8, nearly a month before the official start of the season, the first pre-season cyclone since Beryl in 2012 and the earliest since Ana in 2003. The formation of Ana marked the start of a series of seven consecutive seasons with pre-season activity, spanning from 2015 to 2021. The season concluded with Kate transitioning into an extratropical cyclone on November 11, almost three weeks before the official end.
Hurricane Cristobal was a moderately strong Atlantic tropical cyclone that affected multiple landmasses from Puerto Rico to Iceland in late August and early September 2014. Slow to develop and inhibited by unfavorable wind shear for most of its duration, the storm formed on August 23 near the Caicos Islands from a long-tracked tropical wave. Moving generally northward, Cristobal gradually intensified despite a ragged appearance on satellite imagery, and passed midway between Bermuda and North Carolina on August 27. The next day, while accelerating northeast, Cristobal achieved its peak strength as a Category 1 hurricane. A colder environment transitioned Cristobal into an extratropical cyclone on August 29, but it retained much of its strength as it sped across the northern Atlantic and struck Iceland on September 1.
Hurricane Jose was a powerful, erratic, and long-lived tropical cyclone, the longest-lived since Hurricane Nadine in 2012. Jose was the tenth named storm, fifth hurricane, and third major hurricane of the 2017 Atlantic hurricane season. Jose developed into a tropical storm on September 5 from a tropical wave that left the west coast of Africa nearly a week prior. A period of rapid intensification ensued on September 6, when Jose reached hurricane intensity. On September 8, it reached its peak intensity as a high-end Category 4 with 1-minute sustained winds of 155 mph. However, due to wind shear, it weakened over the next few days as it completed an anti-cyclonic loop north of Hispaniola. Despite weakening to a tropical storm on September 14, Jose managed to regain hurricane intensity the next day as it began to curve northward. Never strengthening above Category 1 status for the remainder of its lifespan, Jose degraded to a tropical storm once again on September 20. Two days later, Jose degenerated into a post-tropical cyclone as it drifted northeastwards off the coast of New England. By September 26, Jose's remnants had dissipated off the East Coast of the United States.
Potential Tropical Cyclone Ten was a damaging storm that was the tenth tropical disturbance designated by the National Hurricane Center (NHC) during the 2017 Atlantic hurricane season. The disturbance was deemed to have a very high chance of becoming a tropical cyclone while posing a threat to populated areas and was designated a "Potential Tropical Cyclone". The storm caused flooding and brought tropical storm-force winds to parts of the Southeastern United States and the Mid-Atlantic states, particularly Florida and the Carolinas, before going on to affect parts of Atlantic Canada. Potential Tropical Cyclone Ten was the tenth storm that had advisories issued on it by the NHC in 2017, and the only such system that failed to fully develop into a tropical cyclone during that Atlantic hurricane season. Potential Tropical Cyclone Ten originated from a tropical wave that moved off the coast of West Africa on August 13. The disturbance slowly tracked its way westward across the Atlantic Ocean, before reaching Florida in late August. The disturbance came close to developing into a tropical storm while it was situated off the coast of the Carolinas; however, strong wind shear and outflow from Hurricane Harvey prevented the storm from organizing into a tropical cyclone. The system transitioned into an extratropical cyclone instead, and became a strong hurricane-force low to the south of Newfoundland, before being absorbed by another extratropical system near Iceland on September 3.
The 2022 Atlantic hurricane season was a destructive and deadly Atlantic hurricane season. Despite having an average number of named storms and below average amount of major hurricanes, it became the third-costliest Atlantic hurricane season on record, behind only 2017 and 2005, mostly due to Hurricane Ian. The season officially began on June 1, and ended on November 30. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean. This year's first Atlantic named storm, Tropical Storm Alex, developed five days after the start of the season, making this the first season since 2014 not to have a pre-season named storm.
Hurricane Beryl was a fast-moving and long-lived tropical cyclone. The second named storm and first hurricane of the 2018 Atlantic hurricane season, Beryl formed in the Main Development Region from a vigorous tropical wave that moved off the west coast of Africa on July 1. The wave quickly organized into a tropical depression over the central Atlantic Ocean on July 4. Rapid intensification took place and the depression quickly became a tropical storm at 00:00 UTC the next day. Just less than 15 hours later, on July 6, Beryl strengthened into the first hurricane of the season, reaching its peak intensity on July 6. Increasingly unfavorable conditions caused a rapid deterioration of the cyclone shortly after its peak, with Beryl falling to tropical storm status on the next day, as it began to accelerate towards the Caribbean. Late on July 8, it degenerated into a tropical wave shortly before reaching the Lesser Antilles. The remnants were monitored for several days, although they failed to organize significantly until July 14, when it regenerated into a subtropical storm, six days after it lost tropical characteristics. However, the newly reformed storm quickly lost convection, and it degenerated into a remnant low early on July 16, while situated over the Gulf Stream. Beryl subsequently dissipated on the next day.
The Bahama Archipelago, also known as the Lucayan Archipelago, is an archipelago comprising the Commonwealth of The Bahamas and the British Overseas Territory of the Turks and Caicos Islands. The archipelago is in the western North Atlantic Ocean, north of Cuba along with the other Antilles, and east and southeast of Florida. The archipelago has experienced the effects of at least 22 Atlantic hurricanes, or storms that were once tropical or subtropical cyclones, including 17 since 2000. The storms collectively killed 101 people.
Hurricane Nicole was a sprawling late-season Category 1 hurricane in November 2022. The fourteenth named storm and eighth hurricane of the 2022 Atlantic hurricane season, Nicole formed as a subtropical cyclone on November 7, from a non-tropical area of low pressure near the Greater Antilles, and transitioned into a tropical cyclone the next day. Then, taking a path similar to that of Hurricane Dorian three years earlier, Nicole made landfall on November 9, on Great Abaco and on Grand Bahama in The Bahamas, where it strengthened into a Category 1 hurricane. On November 10, it made landfall twice in Florida, south of Vero Beach and then northwest of Cedar Key, after briefly emerging over the Gulf of Mexico. Nicole then weakened to a depression while moving over the Florida Panhandle, and then was absorbed into a mid-latitude trough and cold front over extreme eastern Tennessee the following day.
