Tropical Storm Karen was a weak tropical storm that impacted the Lesser Antilles,Virgin Islands,and Puerto Rico in September 2019. The twelfth tropical cyclone and eleventh named storm of the 2019 Atlantic hurricane season,it originated from a tropical wave which entered the tropical Atlantic on September 14. The wave quickly organized as it neared the Windward Islands on September 20,becoming a tropical depression just two days later. The depression strengthened into Tropical Storm Karen later that day,as it moved across the southern Windward Islands. By 18:00 UTC that day,Karen had reached its first peak intensity with 1-minute sustained winds of 45 mph (72 km/h) and a minimum pressure of 1,003 millibars (29.6 inHg ). Karen weakened back to a tropical depression at 06:00 UTC on September 23. However,just 12 hours later,Karen re-intensified into a tropical storm. It then entered the central Atlantic,early the next day. Karen began to degrade on September 27,when it weakened into a tropical depression,due to strong wind shear. The system subsequently degenerated into a surface trough later that day. [1]
Karen caused significant flooding and widespread power outages in Trinidad and Tobago. Damage on the island of Tobago reached $3.53 million (USD). Flooding and power outages also occurred in Puerto Rico where roughly 29,000 customers lost electricity. Only minimal impacts were reported in Venezuela,the remainder of the Windward Islands,and the British Virgin Islands.
On September 14, a tropical wave moved off the west coast of Africa. The wave was accompanied by a large area of convection, or showers and thunderstorms as it moved over the Cabo Verde Islands. However, convective activity started to become disorganized as the wave moved across the tropical Atlantic. [1] The National Hurricane Center (NHC) began to monitor the system for tropical cyclogenesis on September 18. [2] On September 20, convection began to blossom once more as the wave moved into an area favorable for development. [3] Early the next day, an area of low pressure formed along the wave axis while it was located roughly 575 miles (925 km) east-southeast of the southern Windward Islands. At 00:00 UTC on September 22, the wave organized into a tropical depression while located 115 miles (185 km) east of Tobago. At this time, the system was being steered to the west-northwest along the southern periphery of a subtropical ridge. [1] Just three hours later, the depression organized into Tropical Storm Karen while located roughly 120 miles (190 km) southeast of St. Vincent. [4] At around 12:00 UTC that day, Karen passed through the Windward Islands just north of Tobago. [5]
Early on September 23, Karen's convective pattern started to become disorganized as it moved into an area of strong northeasterly vertical wind shear and dry air. At 6:00 UTC on September 24, Karen weakened into a tropical depression as it shifted to the northeast. [1] Early on September 25, deep convection began to slowly increase, however, thunderstorm activity remained south of the center due to north-northeasterly wind shear. [6] Although just a few hours later, thunderstorm activity began to flourish over the storm's center. [1] At 6:00 UTC that day, Karen re-attained tropical storm status while located roughly 90 miles (140 km) southwest of St. Croix. [7] Karen began to slow its forward movement and shift northward around the western periphery of the subtropical ridge. [1] By 18:00 UTC, the storm's center reformed slightly to the west. [8] At 0:00 UTC on September 25, the storm reached its initial peak intensity with one-minute sustained winds of 45 mph (72 km/h) and a minimum central pressure of 1,003 mbar (29.6 inHg), as it moved over the islands of Culebra and Vieques. [9] Later that day, Karen entered the central Atlantic. [1]
On September 26, convection developed over Karen's center. At 9:00 UTC that day, the storm reached its second peak intensity with winds of around 45 mph (72 km/h) and a minimum pressure of 1,004 mbar (29.6 inHg). [1] [10] However, later that day, Karen's circulation became elongated, and weakening occurred early on September 27. [11] [12] A few hours later, the NHC noted that the storm's circulation had attached to a surface boundary that extended from the remnants of Hurricane Jerry. [13] At 12:00 UTC on September 27, Karen degraded into a tropical depression. [1] Just nine hours later, the system degenerated into a surface trough while located roughly 425 miles (684 km) east-southeast of Bermuda. [14]
On September 22, a Tropical Storm Warning was issued for Trinidad and Tobago. [15] However, the warning was discontinued just a few hours later. [16] The entire country was placed under a red alert due to the storm. Regional corporations handed out sandbags in parts of eastern and southern Trinidad. [17] Some sports games were delayed or cancelled due to the storm. Caribbean Airlines cancelled numerous flights in the country. [18] Residents of the country were asked to avoid floodwaters for health and safety reasons. [19]
Heavy rainfall caused flash flooding across Trinidad and Tobago. Severe flooding was reported in southwestern Tobago and Scarborough. In Trinidad, the Sandy River overtopped its bank, causing flooding in Mason Hall. Nearby, a mudslide caused a road to shut down and a house was destroyed. In Plymouth, seven boats sank after Jetty was damaged. [20] [21] In Mt. Lambert, fields were inundated by floodwaters. [22] However, most of Trinidad was spared from major damage. [23] Some of the worst impacts in the country were located in Tobago. [24] A road in Tobago was littered with downed trees and utility poles. [25] During the storm, eight boats were destroyed in Roxborough, causing more than $50,000 TTD ($7,400 USD) in damage. [26] The Tobago Emergency Management Agency (TEMA) stated that Karen caused $24 million TTD ($3.53 million USD) in damage in Tobago. [27] TEMA also stated that it had received 88 reports of incidents related to Tropical Storm Karen. [28]
On September 22, Tropical Storm Watches were first issued in Puerto Rico, including the Spanish Virgin Islands, and the US Virgin Islands. [29] These were upgraded into Tropical Storm Warnings by 9:00 UTC on September 23. [30] All were discontinued by 9:00 UTC on September 25. [31] A flash flood warning was issued for large portions of Puerto Rico by the National Weather Service (NWS). [32] Governor Wanda Vázquez declared a state of emergency for Puerto Rico on September 23. [33] Schools and government buildings were shut down with the threat of heavy rainfall and flooding. [34] Across the island, the government opened 67 shelters. [32] In the U.S. Virgin Islands, schools and government buildings were also closed. Ports were shut down while Seaborne Airlines and Sea Flight cancelled flights between St. Croix and St. Thomas. Also on St. Thomas, traffic was closed on part of Veterans Drive between September 24–25. [35] The Virgin Islands Waste Management Authority advised residents and solid waste haulers that Anguilla's landfill on St. Cross was closed due to deteriorating road conditions. The haulers were asked to hold the waste. [36] Search operations for a 48-year-old woman from Kentucky who went missing at the Virgin Islands National Park had to be briefly suspended due to the storm. [37]
Karen dropped a peak precipitation amount of 5 inches (130 mm) in Coamo, where a bridge was swept away, isolating 15 families. [38] [39] Numerous roads across the island were flooded and became impassible due to mudslides and runoff. [40] River floods were reported in Utuado, Jayuya and Yabucoa municipalities with a mudslide also occurring in Jayuya municipality. [41] The Culebrinas River overtopped its banks, causing flooding in Aguadilla. [42] Roughly 29,000 customers lost electricity in Puerto Rico. [43] A mudslide blocked part of Puerto Rico Highway 14 in Aibonito. [44] In Toa Baja, two people were trapped in a house by flooding. [45] Another home was inundated by floodwaters in the municipality. [46] Flooding trapped one person in their vehicle in Dorado. [47] In the territory, a total of 217 people were displaced by the storm. [42] The director of Puerto Rico's Disaster Management Agency, Carlos Acevedo, stated that Karen caused no major damage in Puerto Rico. [48] In the U.S. Virgin Islands, the storm caused flash flooding, mudslides, and some power outages. [49] Karen set a daily rainfall record at the Cyril E. King Airport in St. Thomas on September 24, with 1.23 in (31 mm) of precipitation being recorded. This broke the former record of 1.02 in (26 mm) from 1990. [50] Foam blocks from a refinery washed onto beaches in southern St. Croix for months after the storm. [51] On September 25, volunteers of the Red Cross assessed damage in six Puerto Rican municipalities. [52] Power restoration in the U.S. Virgin Islands were completed by September 28. [53]
When Karen formed on September 22, Tropical Storm Warnings were issued for Grenada and Saint Vincent and the Grenadines. [15] [54] These warnings were cancelled by September 23. [55] Karen caused tropical storm conditions in Grenada, where Flood and Landslide warnings were issued. [56] In nearby Saint Vincent and the Grenadines, a Flood Watch was issued for the country with the threat of heavy rainfall. [57] A government shutdown occurred due to the storm on September 22. [58] The Kingstown port briefly ceased operations that same day. [59] Gusty winds, rough surf, and downed trees were reported on Union Island. [60] Rough seas caused rocks to be pushed up onto a bar at the Liming in Bequia. [59] In Venezuela, heavy rainfall affected Caracas and Güiria. In the latter, some areas lost power and several homes were flooded. [61] On September 23, a Tropical Storm Warning was issued for the British Virgin Islands, which was later cancelled on September 25. [62] [31] In preparation for the storm, both public and private schools were forced to close. Many stores also closed along with banks, some clinics, ports, and airports. Strong winds and heavy rainfall were reported in portions of the islands. Falling trees snapped power lines, causing power outages. However, the Department of Disaster Management recorded no major damage. [63]
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 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.
Hurricane Jeanne was the deadliest tropical cyclone in the Atlantic basin since Mitch in 1998, and the deadliest tropical cyclone worldwide in 2004. It was the tenth named storm, the seventh hurricane, and the fifth major hurricane of the season, as well as the third hurricane and fourth named storm of the season to make landfall in Florida. After wreaking havoc on Hispaniola, Jeanne struggled to reorganize, eventually strengthening and performing a complete loop over the open Atlantic. It headed westwards, strengthening into a Category 3 hurricane and passing over the islands of Great Abaco and Grand Bahama in the Bahamas on September 25. Jeanne made landfall later in the day in Florida just two miles from where Hurricane Frances had struck a mere three weeks earlier.
Hurricane Marilyn was the most powerful hurricane to strike the Virgin Islands since Hurricane Hugo of 1989, and the third such tropical cyclone in roughly a two-week time span to strike or impact the Leeward Islands, the others being Hurricane Iris and the much more powerful and destructive Hurricane Luis. The thirteenth named storm, seventh hurricane and third major hurricane of the extremely active 1995 Atlantic hurricane season, Marilyn formed on September 12 as a tropical depression from a tropical wave that moved off the coast of Africa on September 7. After formation, the storm quickly became a tropical storm, and steadily intensified into a hurricane by the time it struck the Lesser Antilles on September 14 at Category 1 strength. Entering the northeastern Caribbean Sea, rapid intensification ensued and it peaked on September 16 north of Puerto Rico as a Category 3 hurricane shortly after it had impacted the U.S. Virgin Islands. A Hurricane Hunter reconnaissance flight reported hail, which is unusual for tropical cyclones. After heading north past Bermuda, Marilyn weakened and became extratropical on September 22. The remnant circulation wandered the Atlantic Ocean from September 23 – October 1, just south of Nova Scotia.
Hurricane Debby caused minor damage in the Greater and Lesser Antilles in August 2000. The seventh tropical cyclone, fourth named storm, and second hurricane of the annual season, Debby developed from a tropical wave east of the Lesser Antilles on August 19. Favorable conditions allowed the depression to become Tropical Storm Debby early on August 20, and further strengthening into a hurricane occurred 24 hours later. Sustained winds peaked at 85 mph (137 km/h) on August 21. Debby made three landfalls on August 22, in Barbuda, Saint Barthélemy, and Virgin Gorda, before re-entering the Atlantic north of Puerto Rico. As Debby moved parallel to the north coast of Hispaniola late on August 23, it weakened back to a tropical storm. The storm tracked westward and weakened further, instead of approaching Florida and strengthening into a major hurricane. While south of eastern Cuba on August 24, Debby was downgraded to a tropical depression, six hours before completely dissipating.
Hurricane Anna impacted Central America and the Windward Islands in July 1961. The first tropical cyclone and first hurricane of the 1961 Atlantic hurricane season, Anna developed on July 20 from an easterly wave located in the Intertropical Convergence Zone (ITCZ) over the Windward Islands. Initially a tropical storm, it moved westward across the Caribbean Sea. Favorable environmental conditions allowed Anna to reach hurricane intensity late on July 20. Early on the following day, the storm strengthened into a Category 2 hurricane on the modern-day Saffir–Simpson hurricane wind scale. Intensification continued, and on July 22, Anna peaked with maximum sustained winds of 105 mph (169 km/h). The hurricane then weakened slightly while approaching the coast of Honduras. Further weakening occurred; when Anna made landfall in Belize on July 24, winds decreased to 80 mph (130 km/h). Anna rapidly weakened over land and dissipated later that day.
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 2017 Atlantic hurricane season was a devastating and extremely active Atlantic hurricane season that became the costliest on record, with a damage total of at least $294.92 billion (USD). The season featured 17 named storms, 10 hurricanes, and 6 major hurricanes. Most of the season's damage was due to hurricanes Harvey, Irma, and Maria. Another notable hurricane, Nate, was the worst natural disaster in Costa Rican history. These four storm names were retired following the season due to the number of deaths and amount of damage they caused. Collectively, the tropical cyclones were responsible for at least 3,364 deaths. The season also had the highest accumulated cyclone energy (ACE) since 2005 with an approximate index of 224 units, with a record three hurricanes each generating an ACE of over 40: Irma, Jose, and Maria. This season featured two Category 5 hurricanes, and the only season other than 2007 with two hurricanes making landfall at that intensity. The season's ten hurricanes occurred one after the other, the greatest number of consecutive hurricanes in the satellite era, and tied for the highest number of consecutive hurricanes ever observed in the Atlantic basin.
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, and the third consecutive season to feature at least one storm making landfall at Category 5 intensity. It was also the seventh season on record to have multiple tropical cyclones reaching Category 5 strength, which would not occur again until 2024. 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 Bertha was an unusual tropical cyclone in early August 2014 that attained hurricane status, despite having a disheveled appearance and an abnormally high atmospheric pressure. The third tropical cyclone and second hurricane of the season, Bertha developed from a tropical wave south of Cape Verde was monitored first for possible tropical cyclogenesis on July 26. Over the following days, it slowly developed and acquired gale-force winds and enough convection to be designated as Tropical Storm Bertha early on August 1. A mostly disorganized cyclone, Bertha quickly moved across the Lesser Antilles, clipping the northern end of Martinique, later that day. During its trek across the eastern Caribbean Sea, its circulation became severely disrupted and it may have degenerated into a tropical wave. On August 3, it traversed the Mona Passage and moved over the Southeastern Bahamas where conditions favored development. Despite an overall ragged appearance on satellite imagery, data from Hurricane Hunters indicated it intensified to a hurricane on August 4; it acquired peak winds of 80 mph (130 km/h) that day. Turning north, and later northeast, Bertha soon weakened as it began to merge with an approaching trough to the west. This merger ultimately took place on August 6, at which time Bertha was declared extratropical well to the south of Nova Scotia. The remnant system raced eastward across the Atlantic and later struck the United Kingdom on August 10. Once over the North Sea, the storm stalled for a few days before resuming its eastward track. It was last noted around the Baltic Sea on August 16.
Hurricane Danny was the first major hurricane to develop between the Lesser Antilles and Western Africa since Hurricane Julia in 2010. The fourth tropical cyclone, and first hurricane of the 2015 Atlantic hurricane season, Danny originated from a well-defined tropical wave that emerged over the Atlantic Ocean on August 14. Traveling west, the system gradually coalesced into a tropical depression by August 18. After becoming a tropical storm later that day, dry air slowed further development. On August 20–21, dry air became removed from the system, and Danny rapidly intensified into a Category 3 hurricane on the Saffir–Simpson hurricane wind scale. Its peak was short-lived as wind shear soon increased and prompted significant weakening. Degrading to a tropical storm by August 23, Danny approached the Lesser Antilles. It degenerated into a tropical wave as it traversed the archipelago on August 24 and was last noted over Hispaniola the following day.
Tropical Storm Bret was the earliest named storm in the calendar year to develop in the Main Development Region of the Atlantic basin on record. The second tropical cyclone of the 2017 Atlantic hurricane season, Bret formed from a tropical wave that had exited off the coast of West Africa on June 12. The disturbance moved swiftly across the Atlantic for several days, steadily organizing despite its low latitude. On June 18, the organization increased enough for the National Hurricane Center (NHC) to begin issuing warnings disturbance while it was located southeast of the Windward Islands. The system continued to organize, and by the next day, it had developed into a tropical storm, the second of the 2017 Atlantic hurricane season. Bret continued moving swiftly to the west and struck Trinidad and Tobago early on June 20, before entering the Caribbean Sea, dissipating shortly afterwards.
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 2019 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. It was the fourth consecutive above-normal Atlantic hurricane season. The season officially began on June 1, 2019, and ended on November 30, 2019. These dates, adopted by convention, historically describe the period in each year when most tropical systems form. However, storm formation is possible at any time of the year, as demonstrated in 2019 by the formation of the season's first named storm, Subtropical Storm Andrea, on May 20. The final storm of the season, Tropical Storm Sebastien, transitioned to an extratropical cyclone on November 25.
Hurricane Dorian was an extremely powerful and catastrophic tropical cyclone, which became the most intense on record to strike The Bahamas. It is tied with the 1935 Labor Day hurricane for the strongest landfall in the Atlantic basin in terms of maximum sustained winds. It is regarded as the worst natural disaster in The Bahamas' recorded history. With winds peaking at 185 mph (295 km/h), it was also one of the most powerful hurricanes recorded in the Atlantic Ocean in terms of 1-minute sustained winds, and the strongest since Wilma in 2005. Dorian was the fourth named storm, second hurricane, the first major hurricane, and the first Category 5 hurricane of the 2019 Atlantic hurricane season. Dorian struck the Abaco Islands on September 1 with maximum sustained winds of 185 mph (295 km/h), tying with the 1935 Labor Day hurricane for the highest wind speeds of an Atlantic hurricane ever recorded at landfall. Dorian went on to strike Grand Bahama at similar intensity, stalling just north of the territory with unrelenting winds for at least 24 hours. The resultant damage to these islands was catastrophic; most structures were flattened or swept to sea, and at least 70,000 people were left homeless. After it ravaged through The Bahamas, Dorian proceeded along the coasts of the Southeastern United States and Atlantic Canada, leaving behind considerable damage and economic losses in those regions.
Hurricane Teddy was a large and powerful tropical cyclone that was the fifth-largest Atlantic hurricane by diameter of gale-force winds recorded. Teddy produced large swells along the coast of the Eastern United States and Atlantic Canada in September 2020. The twentieth tropical depression, nineteenth named storm, eighth hurricane, and second major hurricane of the record-breaking 2020 Atlantic hurricane season, Teddy initially formed from a tropical depression that developed from a tropical wave on September 12. Initially, the depression's large size and moderate wind shear kept it from organizing, but it eventually intensified into Tropical Storm Teddy on September 14. After steadily intensifying for about a day, the storm rapidly became a Category 2 hurricane on September 16 before westerly wind shear caused a temporary pause in the intensification trend. It then rapidly intensified again on September 17 and became a Category 4 hurricane. Internal fluctuations and eyewall replacement cycles then caused the storm to fluctuate in intensity before it weakened some as it approached Bermuda. After passing east of the island as a Category 1 hurricane on September 21, Teddy restrengthened back to Category 2 strength due to baroclinic forcing. It weakened again to Category 1 strength the next day before becoming post-tropical as it approached Atlantic Canada early on September 23. It then weakened to a gale-force low and made landfall in Nova Scotia with sustained winds of 65 mph (105 km/h). The system weakened further as it moved northward across eastern Nova Scotia and then the Gulf of St. Lawrence, before being absorbed by a larger non-tropical low early on September 24, near eastern Labrador.
Tropical Storm Fred was a tropical cyclone which affected much of the Greater Antilles and the Southeastern United States in August 2021. The sixth tropical storm of the 2021 Atlantic hurricane season, Fred originated from a tropical wave first noted by the National Hurricane Center on August 4. As the wave drifted westward, advisories were initiated on the wave as a potential tropical cyclone by August 9 as it was approaching the Leeward Islands. Entering the Eastern Caribbean Sea after a close pass to Dominica by the next day, the potential tropical cyclone continued northwestward. By August 11, the disturbance had formed into Tropical Storm Fred just south of Puerto Rico, shortly before hitting the Dominican Republic on the island of Hispaniola later that day. The storm proceeded to weaken to a tropical depression over the highly mountainous island, before emerging north of the Windward Passage on August 12. The disorganized tropical depression turned to the west and made a second landfall in Northern Cuba on August 13. After having its circulation continuously disrupted by land interaction and wind shear, the storm degenerated into a tropical wave as it was turning northward near the western tip of Cuba the following day. Continuing north, the remnants of Fred quickly re-organized over the Gulf of Mexico, regenerating into a tropical storm by August 15. Fred continued towards the Florida Panhandle and swiftly intensified to a strong 65 mph (105 km/h) tropical storm before making landfall late on August 16 and moving into the state of Georgia. Afterward, Fred continued moving north-northeastward, before degenerating into an extratropical low on August 18. Fred's remnants later turned eastward, and the storm's remnants dissipated on August 20, near the coast of Massachusetts.
Hurricane Bonnie was a strong tropical cyclone that survived the crossover from the Atlantic Ocean to the Pacific Ocean, the first to do so since Hurricane Otto in 2016. The second named storm of the 2022 Atlantic hurricane season, it originated from a strong tropical wave that moved off the west coast of Africa on June 23. Moving with little development despite favorable conditions, the National Hurricane Center (NHC) started advisories on it as Potential Tropical Cyclone Two late on June 27, due to its imminent threat to land. The disturbance finally organized into Tropical Storm Bonnie at 13:15 UTC on July 1, and made brief landfalls on the Costa Rica–Nicaragua border with winds of 50 miles per hour (80 km/h). It later became the fourth named storm, third hurricane, and first major hurricane of the 2022 Pacific hurricane season after crossing Nicaragua and Costa Rica from east to west on July 2 and intensifying to a Category 3 hurricane on July 5. Bonnie rapidly weakened, dissipating over the North Pacific.
Hurricane Fiona was a large, powerful, and destructive tropical cyclone which was the costliest and most intense tropical or post-tropical cyclone to hit Canada on record. It was the sixth named storm, third hurricane and first major hurricane of the 2022 Atlantic hurricane season.
