Tropical Storm Arthur The first tropical depression of the season formed on May 16 about east of
Melbourne, Florida. It quickly intensified into Tropical Storm Arthur, reaching peak winds of and a minimum barometric pressure of on May 19. A day later, Arthur interacted with a non-tropical front and became an extratropical cyclone. The low turned southeast before dissipating near Bermuda a day later. The precursor of Arthur dropped heavy rainfall over portions of the Bahamas, Cuba, and Florida, reaching near
Marathon, Florida. Arthur later produced rainfall and storm surge flooding across North Carolina. In Florida, the precursor of Bertha brought up to of rainfall and localized flooding to the Miami area. One person drowned in South Carolina due to rip currents generated by the storm. Overall, Bertha left at least $133,000 in damage.
Tropical Storm Cristobal On June 1, the
remnants of
Eastern Pacific Tropical Storm Amanda entered the
Bay of Campeche, quickly redeveloping into Tropical Depression Three. On the next day, it strengthened into Tropical Storm Cristobal, which strengthened while moving southeastward. The storm made landfall just west of
Ciudad del Carmen at 13:35 UTC on June 3 at its peak intensity of . Cristobal weakened into a tropical depression over land, but restrengthened as it moved back over the Gulf of Mexico. Cristobal dropped rainfall throughout the Yucatán Peninsula, reaching . Three people died in Mexico due to the storm. Once back over water, Cristobal reattained winds of before encountering unfavorable conditions. Late on June 7, the storm moved ashore southeastern Louisiana, and weakened to a tropical depression as it continued northward. Cristobal became an extratropical low on June 10 over Iowa, and lasted two more days before dissipating over the
Hudson Bay. Cristobal killed three people in the United States.
Tropical Storm Edouard A weak
frontal system led to the development of a tropical depression on July 4, located about west-southwest of
Bermuda. The depression passed about northwest of Bermuda around 08:00 UTC on July 5, producing wind gusts of 43 mph (68 km/h). Moving northeastward, the depression strengthened into Tropical Storm Edouard on July 6, reaching peak winds of and a minimum barometric pressure of . Soon after, Edouard merged with an approaching frontal system, which continued across the Atlantic Ocean, eventually moving across Ireland and Great Britain. The low dissipated on July 9. Edouard's extratropical remnants brought rainfall to western Europe.
Tropical Storm Fay The same trough that produced Tropical Storm Edouard also produced an area of thunderstorms over the northern Gulf of Mexico on July 5. After moving across the southeastern United States, the system developed into Tropical Storm Fay on July 9 near Cape Hatteras, North Carolina. Moving northward, the storm reached peak winds of and a minimum pressure of 998 mbar (29. 47 inHg) late on July 10. At 20:00 UTC that day, Fay made landfall near
Atlantic City, New Jersey, with winds of . It quickly lost intensity inland, degenerating into a remnant low while over southeastern
New York and later being absorbed into a larger mid-latitude low over southeastern Canada. Fay directly caused the deaths of two people, who drowned due to rip currents; four others drowned due to the residual high surf conditions after Fay had passed by. New Jersey experienced some of the worst impacts from Fay. Heavy rainfall caused flooding in several
Jersey Shore towns and resulted in closures along many
roadways, including the
New Jersey Turnpike. Wind gusts up to left at least 10,000 people in the state without electricity.
Tropical Storm Gonzalo A dry,
thermal low-pressure area merged with a
tropical wave just offshore the west coast of Africa on July 15. Moving westward, the system developed into a tropical depression late on July 21 about east of the Windward Islands. With light wind shear warm waters, the depression intensified into Tropical Storm Gonzalo, reaching peak winds of and a minimum pressure of at 06:00 UTC on July 23. Dry air from the Saharan Air Layer significantly disrupted the thunderstorms, while stronger wind shear caused weakening. Gonzalo fell to tropical depression status before making landfall on
Trinidad on July 25. The system degenerated into a trough early the next day near the coast of
Venezuela. The storm brought stormy weather to Trinidad and Tobago and parts of southern Grenada. Only two reports of wind damage were received: a fallen tree on a health facility in Les Coteaux and a damaged bus stop roof in Argyle.
Hurricane Hanna A tropical wave moved through Florida into the Gulf of Mexico, leading to the formation of a tropical depression at 00:00 UTC on July 23 about south-southeast of Louisiana. Moving to the west-northwest, the depression soon intensified into Tropical Storm Hanna, developing an eye. Hanna reached hurricane status on July 25, reaching peak winds of and a minimum pressure of before making landfall on
Padre Island, Texas, and later the
Kenedy County mainland. The system rapidly weakened after moving inland, dropping to tropical depression status at 18:00 UTC on July 26 near
Monterrey,
Nuevo León, and then dissipating shortly thereafter. In
Walton County, Florida, a 33-year-old man drowned in rip currents while rescuing his son. Isaias caused 17 deaths across the Greater Antilles and eastern United States: 14 in the continental United States, 2 in the Dominican Republic, and 1 in Puerto Rico. Damage estimates exceeded $4.8 billion. Isaias caused devastating flooding and wind damage in Puerto Rico and the Dominican Republic. In the United States, Isaias produced an outbreak of 39 tornadoes, including an EF3 tornado in North Carolina that killed two people. Strong winds, storm surge, and many tornadoes left significant damage in the Northeastern United States. Almost 3 million people were without electricity at the height of the storm.
Tropical Storm Josephine In early August, a tropical wave moved across the tropical Atlantic, leading to the formation of Tropical Depression Eleven at 06:00 UTC on August 11 about west-southwest of the Cabo Verde Islands. Dry air and wind shear prevented further strengthening at first, but after a drop in shear, the depression became Tropical Storm Josephine at 12:00 UTC on August 13, with winds of . Continued wind shear caused the storm to fluctuate in intensity, and Josephine weakened to a tropical depression on August 16 while passing north of the
Leeward Islands. Soon thereafter, the system degenerated into a trough of low pressure.
Tropical Storm Kyle A
mesoscale convective system moved offshore of South Carolina and Georgia early on August 11, which became better organized as it moved up the coast. The system developed into Tropical Storm Kyle around 12:00 UTC on August 14, about east-northeast of Duck, North Carolina. It moved quickly east-northwestward, reaching a peak intensity on August 15 with peak winds of and a minimum pressure at while located about southeast of Cape Cod, Massachusetts. Kyle subsequently weakened due to wind shear, and it became an extratropical cyclone early on August 16, soon after dissipating within the front. Several days later, extratropical
European windstorm Ellen, which contained remnants of Tropical Storm Kyle, brought hurricane-force winds to the
Republic of Ireland and the
United Kingdom.
Hurricane Laura On August 20, a tropical depression formed in the open Atlantic Ocean, which quickly intensified into Tropical Storm Laura. Wind shear prohibited further intensification as the storm moved across the northern Leeward Islands, the Dominican Republic, and later Cuba. Laura entered the Gulf of Mexico on August 25, quickly becoming a hurricane, and subsequently underwent
rapid intensification as it moved toward Louisiana. At 00:00 UTC on August 27, Laura reached its peak intensity with maximum sustained winds of and minimum pressure while located just offshore Louisiana, making it a Category 4 hurricane. Shortly thereafter, Laura made its final landfall near
Cameron, Louisiana, at 06:00 UTC, becoming the strongest tropical cyclone in terms of wind speed since the
1856 Last Island hurricane. Laura weakened over land, dropping to tropical depression status over Arkansas by August 28. The deteriorating system turned northeastward and degenerated into a
remnant low over
northern Kentucky on August 29, which was soon absorbed by another low near the
Great Lakes region. As Laura passed through the Northern Leeward Islands, it brought heavy rainfall to
Guadeloupe and
Dominica, and prompted the closing of all ports in the
British Virgin Islands. The storm produced heavy downpours upon Puerto Rico and Hispaniola. The storm left extensive damage in Louisiana, especially in the
southwest region of the state. Storm surge penetrated up to nearly inland, while Creole and
Grand Chenier were inundated with coastal floodwaters ranging from above ground, sweeping away structures in
Cameron Parish. Wind gusts reached up to at
Holly Beach, resulting in catastrophic wind damage in
Calcasieu and Cameron parishes. Outside of the two parishes,
Beauregard and
Vernon parishes were next hardest hit, with the core of the storm passing directly over. Several other parishes reported damage to homes and buildings due to strong winds or falling trees. Damage in Louisiana alone totaled about $17.5 billion.
Texas was second hardest hit by the storm, with high winds downing many power lines, power poles, and trees in the
eastern part of the state, while some counties reported damage to businesses and homes. Laura produced 16 tornadoes in the United States, the most significant of them being an EF2 tornado in
Randolph County, Arkansas. Altogether, there were 81 storm related deaths. Of these, 47 were direct deaths associated with Laura, including 31 in Haiti, 9 in the Dominican Republic, and 7 in the United States. There were also 34 indirect deaths, all of them in the United States. Rainfall in western Cuba reached at
Cape San Antonio, causing flash flooding. Marco became a hurricane on August 23 in the southeastern Gulf of Mexico, with maximum sustained winds of and a minimum pressure of . Stronger wind shear caused Marco to weaken to a tropical storm on August 24 as it was approaching the coast of Louisiana. The storm turned westward and avoided moving ashore, degenerating into a remnant low on August 25 without making landfall. Overall, Marco left approximately $35 million in damage throughout its path.
Hurricane Nana Toward the end of August, a tropical wave moved through the Caribbean Sea, with a concentrated area of convection. On September 1, Tropical Storm Nana developed about southeast of
Kingston, Jamaica. Despite the presence of wind shear, the storm was able to intensify, becoming a hurricane early on September 3 near the coast of
Belize. At that time, Nana had maximum sustained winds of and a minimum pressure of . Soon after, the hurricane made landfall about south of
Belize City, and it rapidly weakened over land, dissipating on September 4. The hurricane caused more than US$20 million in damage in Belize. Heavy amounts of precipitation also occurred in northern Guatemala and southeastern Mexico. The remnants later regenerated into
Tropical Storm Julio in the eastern Pacific on September 5. Paulette caused two fatalities and one injury, due to rip currents along the east coast of the United States. Paulette produced hurricane-force winds on Bermuda, with sustained winds reaching at Pearl Island and surface-level gusts reaching at
L.F. Wade International Airport. The hurricane led to 25,000 power outages, or about 70 percent of electrical customers on the island. Damage on Bermuda totaled approximately $50 million. Rene weakened to a tropical depression several hours, but re-strengthened into a tropical storm early on September 9. At 12:00 UTC on September 10, Rene peaked with sustained winds of and a minimum pressure of . Dry air caused thunderstorms to diminish, and Rene weakened to a tropical depression on September 12. Strong westerly shear caused further weakening, with Rene degenerating into a trough on September 14 about northeast of the Leeward Islands. The
remnants turned southwestward and dissipated a few days later.
Hurricane Sally In early September, a trough developed over the western Atlantic, leading to the formation of Tropical Depression Nineteen on September 11 over the Bahamas. Moving westward, the depression made landfall near
Cutler Bay, Florida, early on September 12. While moving over the
Everglades, the depression strengthened into Tropical Storm Sally, which soon emerged into the Gulf of Mexico. Sally moved northwestward, intensifying into a hurricane on September 14. The hurricane slowed to a crawl while turning north-northeastward, becoming a high-end Category 2 hurricane by 06:00 UTC September 16. At around 09:45 UTC that day, the system made landfall at peak intensity near
Gulf Shores, Alabama, with maximum sustained winds of and a minimum central pressure of . Sally quickly weakened over land, becoming an extratropical low on September 17, which was later absorbed within a cold front. Across the United States, Sally was responsible for nine fatalities and approximately $7.3 billion in damage. The storm caused widespread power outages affecting at least 560,000 people. In its early stages, Sally dropped heavy rainfall in South Florida, causing flooding. The hurricane destroyed approximately 50 structures in the
Florida Panhandle, while thousands of others in
Escambia and
Santa Rosa counties suffered damage. There were 23 tornadoes reported across the Southeastern United States while Sally was a tropical cyclone. Hurricane Teddy generated large ocean swells which spread along much of the U.S. Atlantic coast and from the northern Caribbean to Bermuda, killing three people. Abnormally high tides also caused coastal flooding in
Charleston, South Carolina, and the
Outer Banks of
North Carolina. About 220 households lost power in Bermuda. The extratropical remnants of Teddy generated wind gusts up to in Nova Scotia. Approximately 18,000 customers throughout the Atlantic Canada region lost electricity. There were also isolated reports of minor flooding. Continuing to the northwest, the system developed into Tropical Depression Twenty-One on September 14, which quickly strengthened into Tropical Storm Vicky. Despite strong wind shear partially caused by Hurricane Teddy's
outflow, Vicky intensified to reach peak winds of and a pressure of on September 15. Continued wind shear caused Vicky to weaken, and the storm dissipated on September 17.
Tropical Storm Beta An area of disturbed weather was first observed on September 5, stretching from the western Caribbean to offshore the Southeastern United States. The influence of nearby Hurricane Sally initially prevented further development. A day after that hurricane moved ashore, Tropical Depression Twenty-Two developed in the Gulf of Mexico on September 17, located about south-southeast of
Brownsville, Texas. On September 18, the depression became Tropical Storm Beta, reaching peak winds of two days later. The storm slowed its movement, resulting in
upwelling, which caused weakening. Beta made landfall early on September 22 near
Port O'Connor, Texas, soon weakening and becoming extratropical. The low dissipated over northeastern Alabama early on September 25.
Tropical Storm Wilfred A tropical wave exited western Africa on September 13. After a well-defined circulation formed within an area of deep convection, the system developed into Tropical Storm Wilfred late on September 17 while situated about southwest of Cabo Verde. It only reached peak winds of and a minimum pressure of , before weakening due to dry air and wind shear. Wilfred weakened to a tropical depression on September 20, and degenerated into an open trough the next day about east of the northern Leeward Islands.
Subtropical Storm Alpha A large extratropical low developed over the northeast Atlantic Ocean on September 14, which moved south-southeastward. The wind field contracted as thunderstorms formed over the circulation. On September 17, the system developed into Subtropical Storm Alpha roughly east of the Azores. Alpha strengthened to attain winds of and a minimum pressure of . At 18:40 UTC on September 18, the cyclone made landfall about south of
Figueira da Foz, Portugal. It dissipated by the next day.
Hurricane Gamma A tropical depression developed on October 2 in the northwestern Caribbean Sea, about southeast of the Yucatán peninsula. It quickly intensified into Tropical Storm Gamma and intensified further into a hurricane, reaching winds of and a minimum pressure of as it made landfall near
Tulum, Quintana Roo on October 3. Gamma weakened over land and emerged into the southern Gulf of Mexico, encountering wind shear and dry air. It weakened into a tropical depression before making another landfall on the Yucatán peninsula on October 6, near
San Felipe, Yucatán. Soon after, Gamma was absorbed by approaching Hurricane Delta. Hurricane Gamma caused at least six deaths in Mexico, while damage was estimated at $100 million. Gamma's outerbands also produced heavy rainfall in the
Cayman Islands,
Cuba, and
Florida.
Hurricane Delta In early October, a tropical wave moved across the Caribbean, leading to the formation of Tropical Depression Twenty-Six on October 4 to the southeast of Jamaica. It intensified into Tropical Storm Delta, and soon began a period of rapid intensification, as convection became more symmetrical. Delta became a hurricane at 00:00 October 6, and later that day peaked as a Category 4 hurricane with maximum winds of and a minimum pressure of . This period of rapid intensification resulted in a increase in winds over a period, caused by a combination of extremely warm ocean water temperatures, low wind shear, and sufficient moisture. However, an increase in wind shear caused Delta to weaken, and on October 7 the hurricane struck the eastern Mexican state of Quintana Roo as a Category 2 hurricane with sustained winds of . Delta weakened over land, but re-intensified over the Gulf of Mexico, reaching a secondary peak of and a minimum pressure of on October 9. Later that day, unfavorable conditions caused the hurricane to weaken, and Delta made its final landfall near
Creole, Louisiana, with winds of . The landfall was about east of where Hurricane Laura's eye crossed the coast on August 27. Inland, Delta weakened to tropical storm, and later became extratropical over Mississippi late on October 10. The system degenerated into a trough over
Tennessee two days later. Hurricane Delta caused six fatalities, two each in the Yucatán, Louisiana, and Florida. In Mexico, damage in Mexico totaled approximately $185 million, with power outages, uprooted trees, and flooding. Damage from Delta in the United States reached $2.9 billion. The hurricane and its remnants produced heavy rain, strong winds, storm surge, and tornadoes across much of the Southeastern United States. In Louisiana, strong winds generated by Delta caused additional damage to structures that were impacted by Laura, while debris remaining from Hurricane Laura were scattered across roadways and drains. However, much of the damage in the state was caused by flooding, with of rainfall at
LeBleu Settlement. Floodwaters entered several homes in
Baton Rouge and
Calcasieu. In Mississippi, roughly 100,000 businesses and homes lost electricity after rainfall and tropical storm-force wind gusts uprooted trees. Epsilon's remnants were later absorbed into a deep extratropical low southwest of
Iceland. The hurricane caused one direct death; a 27-year-old man drowned in Epsilon-induced rip currents in
Daytona Beach, Florida. The hurricane also generated large sea swells from Bermuda to the Bahamas, the Greater Antilles, and the Leeward Islands. Rainfall on the island as the storm passed by amounted to less than ; winds at
Bermuda's airport gusted near tropical storm-force, with a peak wind gust of .
Hurricane Zeta The interaction of a tropical wave and a midlevel trough led to the formation of Tropical Depression Twenty-Eight on October 24 near Grand Cayman. It quickly intensified into Tropical Storm Zeta, and reached hurricane status on October 26. That day, Zeta made landfall near
Ciudad Chemuyil, Quintana Roo, with winds of . After weakening to a tropical storm inland, Zeta moved offshore of the northern coast of the Yucatán Peninsula about 11 hours later. On October 28, it reattained hurricane status as it turned northward. Zeta peaked later that day at 21:00 UTC when it became a Category 3 major hurricane with maximum sustained winds of and a minimum barometric pressure of , as it made its second landfall near
Cocodrie, Louisiana. Zeta steadily lost strength after landfall, weakening to a tropical storm over Alabama at 06:00 UTC on October 29, before transitioning into a post-tropical cyclone over central Virginia by 18:00 UTC that day, while moving rapidly northeastward. Early on October 30, Zeta's remnants dissipated east of the
mid-Atlantic U.S. coast. Heavy rain in
Jamaica caused a landslide that killed two people after demolishing a home in
Saint Andrew Parish. Zeta left roughly $15 million in damage on the island. There were seven related deaths in the United States: three in Georgia; two in Mississippi; and one each in Louisiana and Mississippi. Damage within the United States totaled $4.4 billion. In Louisiana, wind gusts reached at
Golden Meadow, Louisiana. Zeta had damaging effects as far northeast as Virginia, while its remnants produced
snow across parts of
New England.
Hurricane Eta Toward the end of October, a tropical wave moved across the Caribbean Sea, leading to the formation of Tropical Depression Twenty-Nine late on October 31. Moving westward, it strengthened into Tropical Storm Eta and continued to intensify rapidly as it approached Central America. Late on November 2, Eta reached peak intensity with sustained maximum winds of and a minimum pressure of at 06:00 UTC on November 3. Later that day, at 21:00 UTC, it made landfall south-southwest of
Puerto Cabezas, Nicaragua, with winds of . Over land, Eta rapidly weakened to a tropical depression and lost its surface circulation, although its mid-level center remained present. On November 6, the system redeveloped into a tropical depression, which again became a tropical storm as it moved to the northeast. Eta struck eastern Cuba as it curved back to the northwest, moving across the Florida Keys into the Gulf of Mexico on November 9. The storm briefly re-strengthened into a hurricane southwest of Florida on November 11, before weakening back to tropical storm strength. It then turned northeastward and made its final landfall near
Cedar Key, Florida, at 09:00 UTC on November 12, with winds of . The storm weakened over land and emerged over the Atlantic Ocean, becoming extratropical on November 13. Overall, more than 210 fatalities across Central America were attributed to the storm, including 74 in Honduras, 60 in Guatemala, 27 in Mexico, 10 in the United States, two each in Nicaragua and Costa Rica, Damage in Central America reached approximately $6.8 billion. The intense wind and rain generated by Eta caused flooding and landslides, resulting in crop losses, plus the destruction of roads, bridges, power lines and houses throughout Central America. The storm damaged or demolished at least 6,900 homes, 45 schools, 16 healthcare facilities, and some of bridges and roadways throughout Nicaragua. Eta also damaged hundreds of dwellings to some degree in both Guatemala and Honduras. Washed-out bridges and roads isolated more than 40 communities in the latter. In Guatemala, flooding also ruined more than of crops. Eta bought heavy rainfall and gusty winds to the Cayman Islands and Cuba, the latter of which was already dealing with overflowing rivers that prompted the evacuations of 25,000 people. The storm caused roughly $1.5 billion in damage in the United States, mostly related to flooding. A non-tropical low subsequently formed about west-southwest of the Azores on November 8. The system became better organized as it began to detach from a frontal boundary during the following day. At 00:00 UTC on November 10, it developed into Subtropical Storm Theta. By 18:00 UTC that afternoon, the storm had transitioned into a tropical storm; it simultaneously attained what would be its peak intensity, with maximum winds of and a minimum pressure of . By the following morning, the effects of strong southwesterly shear had weakened Theta somewhat, though it soon began to regain some strength, and by 00:00 UTC on November 12, re-intensified to its earlier peak. Steady weakening occurred on , as the storm experienced strong northerly vertical shear. By 06:00 UTC on November 15, Theta had weakened to a tropical depression about southwest of
Madeira Island, and it degenerated to a remnant low six hours later.
Hurricane Iota A tropical wave exited the west coast of Africa on October 30, which eventually led to the formation of Tropical Depression Thirty-One on November 13. The depression intensified into Tropical Storm Iota as it moved westward through an area of warm waters and low wind shear. Iota rapidly intensified, becoming a hurricane on November 15, and reaching its peak intensity a day later with maximum winds of and a minimum pressure of , while located just northwest of Providencia Island. The hurricane weakened slightly before making landfall at 03:40 UTC on November 17 in eastern Nicaragua with sustained winds of . Iota rapidly weakened over land, dissipating late on November 18 over El Salvador. Its landfall location was approximately south of where Eta made landfall on November 3. Hurricane Iota caused at least 84 deaths along its path and resulted in about $1.4 billion in damage. The storm first affected Venezuela, damaging homes in
Falcón state. Iota demolished approximately 98 percent of the infrastructure on Providencia Island, while also damaging hundreds of houses. Most of the damage occurred in Nicaragua and Honduras. In the former, wind damage was limited to an extent due to the recent passage of Hurricane Eta. However, the cyclone knocked down many electrical poles and deroofed many homes and a makeshift hospital in the
Puerto Cabezas area. Heavy rainfall, combined with already saturated soil due to Eta, caused widespread flooding and mudslides. Heavy precipitation resulted in flooding and mudslides in Honduras, especially close to or north of Iota's path, completely destroying numerous homes. Mexico also reported extensive impacts from the storm, especially in
Chiapas,
Tabasco, and
Veracruz. Floodwaters and mudslides damaged almost 59,000 homes and left 135 communities isolated. ==Storm names==
