2020 Atlantic hurricane season#Tropical Storm Vicky

Forecasts of hurricane activity are issued before each hurricane season by noted hurricane experts, such as Philip J. Klotzbach and his associates at Colorado State University (CSU), and separately by NOAA forecasters. Klotzbach's team (formerly led by William M. Gray) defined the average (1981 to 2010) hurricane season as featuring 12.1 tropical storms, 6.4 hurricanes, 2.7 major hurricanes (storms reaching at least Category 3 strength in the Saffir–Simpson scale), and an accumulated cyclone energy (ACE) index of 106 units. Broadly speaking, ACE is a measure of the power of a tropical or subtropical storm multiplied by the length of time it existed. It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of {{Cvt|39|mph}}. NOAA defines a season as above normal, near normal or below normal by a combination of the number of named storms, the number reaching hurricane strength, the number reaching major hurricane strength, and the ACE Index.

The first seasonal forecast was released on December 19, 2019, by Tropical Storm Risk (TSR), a public consortium consisting of experts on insurance, risk management, and seasonal climate forecasting at University College London, anticipating a slightly above-average hurricane season. This forecast was based on the prediction of near-average trade winds and slightly warmer than normal sea surface temperatures as well as a neutral El Niño–Southern Oscillation (ENSO) phase in the equatorial Pacific.{{cite web|title=Extended Range Forecast for Atlantic Hurricane Activity in 2020|url=http://tropicalstormrisk.com/docs/TSRATLForecastDec2020.pdf|work=Tropical Storm Risk|publisher=Department of Space and Climate Physics, University College London|access-date=December 19, 2019|author1=Mark Saunders|author2=Adam Lea|date=December 19, 2019|archive-date=December 19, 2019|archive-url=https://web.archive.org/web/20191219164510/http://tropicalstormrisk.com/docs/TSRATLForecastDec2020.pdf|url-status=live}} In April and May 2020, various agencies issued forecasts for the season, with a hyperactive season predicted by the University of Arizona (UA) and North Carolina State University. The CSU anticipated heightened probabilities for hurricanes striking the Caribbean and the United States. On May 20, the UK Met Office predicted average activity with 13 tropical storms, 7 hurricanes, and 3 major hurricanes. A day later, NOAA released their forecast for an above-normal season, citing the continued ENSO-neutral or even La Niña conditions during the peak of the season.

After the season began, agencies updated their forecasts and generally anticipated an active year. The Atlantic experienced anomalously low wind shear and surface pressures during the month of July, leading to forecasts for a near-record-breaking season. The CSU and TSR predicted a total of 24 named storms, and NOAA predicted between 19 and 25 named storms. This was one of the most active forecasts ever released by NOAA for an Atlantic hurricane season.

However, tropical cyclogenesis began in the month of May, with tropical storms Arthur and Bertha, marking the sixth consecutive year with an off-season storm. It was the first year with two pre-season storms since 2016, and the first to have two named storms in May since 2012.{{cite news|url=https://weather.com/safety/hurricane/news/2020-05-27-2020-atlantic-hurricane-season-two-may-tropical-storms|title=Two Tropical Storms Form Before June 1 – Does That Mean an Active Hurricane Season Is Guaranteed?|author=Jonathan Erdman|date=May 27, 2020|newspaper=The Weather Channel|access-date=August 9, 2021|archive-date=August 9, 2021|archive-url=https://web.archive.org/web/20210809201341/https://weather.com/safety/hurricane/news/2020-05-27-2020-atlantic-hurricane-season-two-may-tropical-storms|url-status=live}} The season featured 31 tropical depressions, 30 of which became tropical or subtropical storms.

A total of 10 tropical cyclones underwent rapid intensification, tying the record set in 1995.

The season extended the warm phase of the Atlantic multidecadal oscillation ongoing since 1995. The warm AMO tends to produce tropical cyclones that are more intense and have longer durations. The presence of a La Niña contributed to the unprecedented amount of activity. Sea surface temperatures across the Atlantic basin were warmer-than-average. A strong west African monsoon, favorable wind patterns from Africa, weaker vertical wind shear all aided in the formation of tropical cyclones. The ACE index for the 2020 Atlantic hurricane season was 180 units,{{cite report|work=Hurricane Research Division; Atlantic Oceanographic and Meteorological Laboratory|publisher=National Oceanic and Atmospheric Administration |title=Atlantic basin Comparison of Original and Revised HURDAT|access-date=August 6, 2017|url=http://www.aoml.noaa.gov/hrd/hurdat/comparison_table.html}} reflecting the season's well-above-average activity.{{cite web|url=https://tropical.colostate.edu/Forecast/2021-06.pdf|title=Extended Range Forecast of Atlantic Seasonal Hurricane Activity and Landfall Strike Probability for 2021|author=Philip Klotzbach|author2=Michael Bell|page=37|author3=Jhordanne Jones|publisher=Colorado State University|location=Fort Collins, Colorado|date=June 3, 2021|access-date=August 10, 2021|archive-date=January 28, 2024|archive-url=https://web.archive.org/web/20240128095805/https://tropical.colostate.edu/Forecast/2021-06.pdf|url-status=live}} Climate change likely played a role in the record-breaking season. Scientific American noted that "As the oceans absorb more and more of the excess heat trapped by greenhouse gases, waters will get warmer earlier in the season, which could help set new records in the future."{{cite magazine|url=https://www.scientificamerican.com/article/in-2020-record-breaking-hurricanes-arrived-early-and-often1/|title=In 2020, Record-Breaking Hurricanes Arrived Early—and Often|date=December 1, 2020|author=Andrea Thompson|author2=Amanda Montañez|magazine=Scientific American|access-date=June 4, 2021|archive-date=May 16, 2021|archive-url=https://web.archive.org/web/20210516095155/https://www.scientificamerican.com/article/in-2020-record-breaking-hurricanes-arrived-early-and-often1/|url-status=live}} A formal attribution study showed that the extreme rainfall was higher than in a counterfactual without climate change, especially for high-intensity storms.{{cite journal |last1=Reed |first1=Kevin A. |last2=Wehner |first2=Michael F. |last3=Zarzycki |first3=Colin M. |title=Attribution of 2020 hurricane season extreme rainfall to human-induced climate change |journal=Nature Communications |date=2022 |volume=13 |issue=1 |pages=1905 |doi=10.1038/s41467-022-29379-1 |pmid=35414063 |pmc=9005694 |bibcode=2022NatCo..13.1905R |language=en |issn=2041-1723}} Matthew Rosencrans, the lead forecaster at the National Weather Service, emphasized that climate change has been linked to the intensity of storms and their slow movements, but not to the amount of activity, which might instead be increasing due to improvements in technology.{{cite magazine|url=https://www.smithsonianmag.com/smart-news/noaa-predicts-another-above-average-atlantic-hurricane-season-180977788/|title=NOAA Predicts Another Above-Average Atlantic Hurricane Season|date=May 21, 2021|author=Theresa Machemer|magazine=Smithsonian|access-date=August 10, 2021|archive-date=August 10, 2021|archive-url=https://web.archive.org/web/20210810225954/https://www.smithsonianmag.com/smart-news/noaa-predicts-another-above-average-atlantic-hurricane-season-180977788/|url-status=live}}

The season featured activity at a record pace. The third named storm and each one from the fifth onwards formed on an earlier date in the year than the corresponding storm in any other season since reliable records began in 1851. In late July, Hanna struck South Texas as the first hurricane of the season. It was followed by the second hurricane of the season, Isaias, which moved through the Caribbean and eastern United States.

Around June 17, an area of disturbed weather developed just north of the Bahamas after part of a tropical wave and an upper-level trough interacted. The disturbance moved north and organized into a low-pressure area early on June 22. Shortly thereafter, the low became a subtropical depression about {{convert|405|mi|km|abbr=on|round=5}} east-southeast of Cape Cod, Massachusetts. Mid-level dry air and sea surface temperatures that were only marginally favorable resulted in very little strengthening on June 22. However, after moving east-northeastward and away from an upper low, the cyclone developed more deep convection and intensified into Subtropical Storm Dolly by 06:00 UTC on June 23. About six hours later, Dolly transitioned into a tropical cyclone and peaked with sustained winds of {{convert|45|mph|km/h|abbr=on}} and a minimum pressure of {{convert|1000|mbar|inHg|abbr=on}}. However, convection rapidly diminished after Dolly moved north of the Gulf Stream and encountered drier air. Early on June 24, Dolly degenerated into a remnant low about {{convert|200|mi|km|abbr=on|round=5}} south of Sable Island. The remnant low continued northeastward and dissipated south of Newfoundland early the next day.{{cite web|url=https://www.nhc.noaa.gov/data/tcr/AL042020_Dolly.pdf|work=Tropical Cyclone Report|title=Tropical Storm Dolly|date=January 19, 2021|author=Eric S.

A tropical wave moved across the Atlantic toward the end of July, leading to the development of Tropical Storm Isaias on July 30 in the eastern Caribbean Sea. Moving northwestward, Isaias struck the Dominican Republic and later the Bahamas as it intensified into a hurricane. Curving to the north, Isaias weakened to tropical storm status, but re-intensified back into a hurricane on August 3. At 03:10 UTC the next day, Isaias made landfall in Ocean Isle Beach, North Carolina, with sustained winds of {{convert|90|mph|km/h|abbr=on}}. It soon weakened into a tropical storm as it passed over the Mid-Atlantic states, before transitioning to an extratropical low around 00:00 UTC on August 5 while situated over central Vermont, and dissipating several hours later over Quebec.{{cite web|url=https://www.nhc.noaa.gov/data/tcr/AL092020_Isaias.pdf|title=Hurricane Isaias|author1=Andy Latto|author2=Andrew Hagen|author3=Robbie Berg|date=April 15, 2021|orig-year=Original report date March 30, 2021|work=Tropical Cyclone Report|publisher=National Hurricane Center|location=Miami, Florida|access-date=April 14, 2021|archive-date=September 18, 2021|archive-url=https://web.archive.org/web/20210918065156/https://www.nhc.noaa.gov/data/tcr/AL092020_Isaias.pdf|url-status=live}}

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.

On August 16, a tropical wave exited Africa and moved across the Atlantic. Four days later, Tropical Depression Thirteen developed about {{convert|980|mi|km|abbr=on}} east-southeast of Antigua, 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 later on August 25, where it became a hurricane around 12:00 UTC that day. Laura then began a period of rapid intensification, and over a {{no wrap|24-hour}} period ending at 00:00 UTC on August 27, it intensified by about {{convert|65|mph|km/h|abbr=on|round=5}}, to Category 4 strength.

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 {{convert|110|mph|km/h|abbr=on|round=5}} and a minimum central pressure of {{convert|965|mbar|inHg|abbr=on}}. Sally quickly weakened over land, becoming an extratropical low on September 17, which was later absorbed within a cold front.{{cite web|author1=Robbie Berg|author2=Bard J.

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.

A tropical wave emerged from the west coast of Africa on September 10, leading to the formation of a tropical depression two days later. On September 14 it intensified into Tropical Storm Teddy, which continued to strengthen while moving across the Atlantic Ocean. Teddy became a hurricane on September 16, and two days later it reached its peak intensity with maximum sustained winds of {{convert|140|mph|km/h|abbr=on}} and a minimum barometric pressure of {{convert|945|mbar|inHg|abbr=on}}. Teddy weakened due to an eyewall replacement cycle and increased wind shear. The cyclone passed about {{convert|230|mi|round=5|abbr=on}} east of Bermuda on September 21 as it turned north-northeastward. Teddy interacted with an approaching trough, causing the hurricane to re-intensify and become more asymmetric. The hurricane became an extratropical cyclone on September 23, and soon after moved ashore Atlantic Canada near Ecum Secum, Nova Scotia, with sustained winds of {{convert|65|mph|round=5|abbr=on}}. The system was eventually absorbed by a larger non-tropical low early on September 24 near eastern Labrador.{{cite web|author=Eric S.

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 {{convert|90|mph|km/h|abbr=on|round=5}} in Nova Scotia. Approximately 18,000 customers throughout the Atlantic Canada region lost electricity. There were also isolated reports of minor flooding. Damage from Teddy in all areas impacted totaled roughly $35 million.

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 {{convert|140|mph|km/h|abbr=on}} and a minimum pressure of {{convert|953|mbar|inHg|abbr=on}}. This period of rapid intensification resulted in a {{convert|105|mph|km/h|abbr=on|round=5}} increase in winds over a {{nowrap|36-hour}} 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 {{convert|105|mph|km/h|abbr=on|round=5}}. Delta weakened over land, but re-intensified over the Gulf of Mexico, reaching a secondary peak of {{convert|120|mph|km/h|abbr=on|round=5}} and a minimum pressure of {{convert|953|mbar|inHg|abbr=on}} 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 {{convert|100|mph|km/h|abbr=on|round=5}}. The landfall was about {{convert|10|mi|km|abbr=on|round=5}} 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.

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 {{convert|17.57|in|mm|abbr=on}} 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.

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 {{convert|150|mph|km/h|abbr=on|round=5}} and a minimum pressure of {{convert|922|mbar|inHg|abbr=on}} 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 {{convert|140|mph|km/h|abbr=on|round=5}}. 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 {{convert|50|mph|km/h|abbr=on|round=5}}. The storm weakened over land and emerged over the Atlantic Ocean, becoming extratropical on November 13.{{cite web|author1=Richard J. Pasch|author2=Brad J.

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 {{convert|155|mph|km/h|abbr=on|round=5}} and a minimum pressure of {{convert|917|mbar|inHg|abbr=on}}, while located just {{convert|23|mi|km|abbr=on}} 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 {{convert|145|mph|km/h|abbr=on|round=5}}.

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 Bilwi 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.

On March 17, 2021, during the joint 42nd and 43rd Sessions of the RA IV Hurricane Committee, the World Meteorological Organization (WMO) retired the name Laura, meaning it will not be used again in the North Atlantic basin. Laura was replaced with Leah, which will first appear on the 2026 season list. The Greek letters Eta and Iota were also retired. The WMO also decided to discontinue use of the Greek alphabet as an auxiliary list. A new supplemental list consisting of 21 given names was put in its place beginning with the 2021 season.{{cite news|title=Bye Alpha, Eta: Greek Alphabet Ditched for Hurricane Names|author=Seth Borenstein|url=https://www.usnews.com/news/news/articles/2021-03-17/assumptions-about-hurricane-season-face-winds-of-change|agency=Associated Press|date=March 17, 2021|newspaper=U.S. News & World Report|access-date=June 19, 2021|archive-date=June 24, 2021|archive-url=https://web.archive.org/web/20210624203319/https://www.usnews.com/news/news/articles/2021-03-17/assumptions-about-hurricane-season-face-winds-of-change|url-status=live}}
