[164] The wave's circulation slowly became more defined over the ensuing several days, with signs of convective organization becoming evident on satellite imagery on the morning of August 11. [2] This unprecedented activity was fueled by a La Niña that developed in the summer months of 2020. The season was also the fifth consecutive season in which at least one Category 5 hurricane formed. 2020-21 South Atlantic hurricane season statistics Storm name Dates active Storm category at peak intensity Max wind (mph ) Min. The final Monthly Weather Summary for the 2020 Atlantic hurricane season has been issued. [479] If a storm named with a Greek letter is retired, the letter name would, under current WMO protocol, "be included with the list of retired names with the year of occurrence, but that letter in the Greek Alphabet would still be used in the future. August 4, 2020 - Is downgraded to a tropical storm as … A pair of Hurricanes games, at the Chicago Blackhawks on March 30 and at … [157], Numerous tropical storm watches and warnings as well as hurricane watches and hurricane warnings were issued for the Lesser Antilles, Greater Antilles, Bahamas, Cuba, and the entire East Coast of the United States.

[249], A tropical storm warning was issued for the Cabo Verde Islands when advisories were first issued on the storm at 09:00 UTC on September 7. This season, like 2019, was also monitored by the Brazil Meteorological Center.. [422] Eta's rapid intensification continued through that day, and by 21:00 UTC it had grown into a Category 4 hurricane. A few days later, Hurricane Delta developed in the Caribbean Sea south of Jamaica and became the ninth hurricane of the season. Street flooding occurred as far away as Nicaragua. [389] The hurricane also generated large sea swells from Bermuda to the Bahamas, the Greater Antilles and the Leeward Islands. It includes their duration, names, damage, and death totals. New tropical storm is 'strengthening' and could make landfall in Gulf Coast this week, forecasters say", "Delta rapidly intensifies to hurricane, forecast to reach Category 3 on path to Gulf Coast", "Hurricane Delta Tropical Cyclone Update", "Hurricane Delta a 'Potentially Catastrophic' Strike on Cancún, Then a U.S. Gulf Coast Danger Beginning Friday Night", "Hurricane Delta Tropical Cyclone Update...Corrected", "Hurricane Delta Moves Into Gulf After Striking, but Mostly Sparing, Mexico", "Tropical Storm Delta Intermediate Advisory Number 22A", "Tropical Depression Delta Advisory Number 24", "Post-Tropical Cyclone Delta Advisory Number 25", "Hurricane Delta has western Louisiana in its crosshairs", "Hurricane Delta: Visitors Ordered to Leave Alabama Barrier Islands; Storm-Weary Louisiana Braces for Hit", "Gov. [138] Hanna continued to strengthen further, reaching its peak intensity with 90 mph (140 km/h) winds by 21:00 UTC on July 25, before making landfall an hour later at Padre Island, Texas. In Florida, Tropical Storm Fay made landfall in the Florida Panhandle in July. The accumulated cyclone energy (ACE) index for the 2020 Atlantic hurricane season reached 179.8 units. [453] At 03:00 UTC on November 10, it developed into Subtropical Storm Theta[454] Satellite images received shortly before 14:00 UTC that afternoon revealed that the storm had sustained winds of 70 mph (110 km/h) and a central pressure of 989 mb (29.21 inHg);[455] this would be its peak intensity. By the morning of October 25, its wind field was beginning to grow again as the hurricane began its extratropical transition; although it continued to produce inner-core convection. Theta’s formation officially made 2020 the busiest hurricane season on record. [117] Six people were directly killed due to rip currents and storm surge associated with Fay. There are no tropical cyclones in the Atlantic at this time. 2020 Hurricane Season Statistics . [241][242] As Paulette accelerated northeastward, it began to start extratropical transition on September 15,[243] which it completed the next day.[244]. [384] At 21:00 UTC that day, a NOAA hurricane hunter aircraft reported that the storm had rapidly strengthened to a Category 3 hurricane, becoming the fourth major hurricane of the season. Tropical Storm Arthur weaved along the Gulf Stream and changed little in intensity as it encountered increasing wind shear. So if you think you were tropically fatigued, you are rightfully so. [12] 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. This season, like 2019, was also monitored by the Brazil Meteorological Center.. An overheating world obliterated weather records in 2020 - an extreme year for hurricanes, wildfires, heat waves, floods, droughts and ice melt - the United Nations' weather agency reported Wednesday, Dec. 2, 2020. Afterward, moderate northerly shear of 15 knots halted the trend and partially exposed the center of circulation, although its pressure continued to drop. The Atlantic hurricane season runs from June 1st through November 30th. A near-concurrent pass from another satellite showed lower winds, and given the conflicting data the NHC determined the system to have not become a tropical storm. The floods killed one person in Praia on September 12. The waters aren’t as warm as farther south, either,” said Judt in an email. Marco ultimately became the third hurricane of the season, but rapidly weakened before making landfall in southeast Louisiana. The state has 187 miles of coastline. [245] It moved eastward over the next day, and became post-tropical for the second time in its lifespan early on September 23[246] and subsequently dissipated. Damage and deaths include totals while the storm was extratropical, a wave, or a low. The organization posted significantly heightened probabilities for hurricanes tracking through the Caribbean and hurricanes striking the U.S. [24] On July 7, Tropical Storm Risk released an updated forecast, calling for 18 named storms, 8 hurricanes, and 4 major hurricanes. [333] Over the next few days, it organized while the extratropical system surrounding it gradually weakened, although its proximity and fast movement towards the coast caused the NHC to lower its odds of development. Hurricanes typically get a massive boost of energy when they pass over warm waters. [94] Heavy rains and damage were reported within the warning areas during Cristobal's passage and the storm caused an estimated US$665 million in damage. Three hours later, it became extratropical while located about 450 miles southeast of Cape Race, Newfoundland.[108]. Considered by many to be theworst hurricane in modern South Carolina history. [116] Three hours later, the center reformed near the edge of the primary convective mass, prompting the NHC to initiate advisories on Tropical Storm Fay at 21:00 UTC July 9, located just 40 miles east-northeast of Cape Hatteras. [250] The warning was discontinued at 21:00 UTC on September 8. [368] By 06:00 UTC on October 10, Delta had weakened to a tropical storm,[369] and by 15:00 UTC to a tropical depression. At least seven fatalities have been confirmed. [268], A tropical storm watch was issued for the Miami metropolitan area when the storm first formed, while numerous watches and warnings were issued as Sally approached the U.S. Gulf Coast. [254] Shortly after moving into the Gulf of Mexico, the system strengthened into Tropical Storm Sally at 18:00 UTC the same day. [195] At 06:00 UTC, Laura made landfall near Cameron, Louisiana, with sustained winds of 150 mph (240 km/h),[196] making it the strongest Louisiana-landfalling hurricane in terms of wind speed since the 1856 Last Island hurricane. [147] The wave gradually organized and became better defined, developing a broad area of low pressure. [38] Over the ensuing 24 hours, Hanna underwent rapid intensification as its inner core and convection became better organized. [261] However, as Sally approached the coast, its eye quickly became better defined and it abruptly began to re-intensify. Of the 30 named storms, 13 developed into hurricanes, and six further intensified into major hurricanes, with one, Hurricane Iota, attaining Category 5 strength on the Saffir–Simpson scale. Dry air and only marginally warm seas caused convection to wane and Rene weakened to a tropical depression several hours later. [150] The storm fluctuated in intensity afterwards, due to strong wind shear and dry air, with its winds peaking at 85 mph (137 km/h) and its central pressure falling to 987 mbar (29.1 inHg). The system reached its peak intensity with winds of 35 mph (55 km/h) and a pressure of 1008 mbar (29.77 inHg) around 00:00 UTC on August 1. Major storm surge is forecast across eastern Louisiana and extending eastward as the storm is becoming larger. If this is correct, we will have to brace ourselves for a significantly active 2020 hurricane season. Several towns were left without electricity and drinking water in Puerto Rico. [481][482], After the 2005 hurricane season, the WMO hurricane committee decided to keep using the Greek letter names as an auxiliary list each year, determining that retiring a Greek letter name by removing the name from use was infeasible. Author Karl Hille Posted on February 28, 2020 February 28, 2020 Categories Earth Hazards, Hurricanes Tags Esther 2020 Ferdinand – Southern Indian Ocean Feb. 28, 2020 – NASA Finds Dry Air Sapping Tropical Cyclone Ferdinand’s Strength At 00:00 UTC July 5, shortly after the formation of Tropical Storm Edouard, the NHC began to track an area of disorganized cloudiness and showers in relation to a nearly stationary surface trough in the Gulf of Mexico. The 2020-21 South Atlantic Cyclone Season was the Second ever official South Atlantic Cyclone season. Thereafter, a combination of decreasing sea surface temperatures and dry air caused convection to dissipate. [468] As Iota was nearing its peak intensity, it passed very close to the Archipelago of San Andrés, Providencia and Santa Catalina, with its eye missing Providencia by only 11 miles (18 km). [nb 2] In late August, Laura made landfall in Louisiana as a Category 4 hurricane, becoming the strongest tropical cyclone on record in terms of wind speed to make landfall in Louisiana, alongside the 1856 Last Island hurricane. [121] The depression transitioned into a post-tropical cyclone three hours later while located roughly 30 mi (45 km) south of Albany, New York. Hurricane Sally made landfall in Gulf Shores on Sept. 16, 2020, 16 years to the day after Alabama's last hurricane landfall (Ivan). Typically by this date in September, we will have had 7 named storms. [232] At 15:00 UTC the same day, the NHC upgraded the system to Tropical Storm Paulette. Seven of those storms have made landfall. [460] By 09:00 UTC the next day, Theta had weakened to a tropical depression,[461] and it degenerated to a remnant low six hours later. [240] The storm then strengthened into a Category 2 hurricane as it accelerated northeast away from the island on September 14, reaching its peak intensify of 105 mph (170 km/h) and a pressure of 965 mb (28.50 inHg) later that day. [128] After Gonzalo failed to strengthen into a hurricane on July 24, the hurricane and tropical storm watches were replaced with tropical storm warnings. Why they retire names?And why hasn't #Dorian been retired? [205] At 15:00 UTC on August 20, the NHC designated the wave as Tropical Depression Fourteen. Delta explosively intensified into a strong Category 4 hurricane before weakening and making landfall on the Yucatán Peninsula on October 7 as a high-end Category 2 hurricane. [372] There were no immediate reports of deaths or injuries, but there were numerous reports of fallen trees and damage to the region's electrical grids. [224] By 18:00 UTC that same day, the storm strengthened some more, obtaining 1-minute sustained winds of 60 mph (95 km/h). Hurricane Laura could bring heavy rain to Mid-South Hurricane Laura update 8/25 By Brittney Bryant | August 25, 2020 at 7:46 AM CDT - Updated August 25 at 8:50 AM Based on Doppler weather radar and buoy data, the system attained peak winds of 50 mph (85 km/h) shortly before moving inland near Isle of Palms. People wade through the flooded community of Wawashang in Nicaragua. Hanna became the first hurricane of the season and struck South Texas, while Isaias became the second hurricane of the season and struck much of the Caribbean and the East Coast of the United States. It degenerated into a remnant low at 00:00 UTC on September 4 before dissipating shortly thereafter. August saw the formations of tropical storms Josephine and Kyle, and hurricanes Laura and Marco. [464] Iota began to rapidly intensify on November 14, as convection started to wrap around its center,[465] and by 06:00 UTC the next day, it reached hurricane strength. [17], On May 20, Mexico's Servicio Meteorológico Nacional released their forecast for an above-average season with 15–19 named storms, 7–9 hurricanes and 3–4 major hurricanes. [290] Later that same day, the hurricane weakened to Category 1 intensity,[291] before becoming a strong post-tropical cyclone at around 00:00 UTC on September 23. It slowly organized and gained convection as it meandered southeast of Bermuda.
