![]() landfalls in 2021 is the third highest on record, behind 2020 (11) and 1916 (nine). in 2021 (though one could argue that the first named storm to hit the U.S., Claudette in southeastern Louisiana on June 19, did not count as a landfall, since it wasn’t named until it was centered over land). ![]() landfalls in two yearsĮight named storms made landfall in the U.S. The trend (blue line) is decidedly upwards. Number of named Atlantic storms lasting two days or less, 1968-2021. Among those tropical cyclones, though, the proportion that reach Category 4 or 5 will very likely increase. According to this year’s Sixth Assessment Report from the Intergovernmental Panel on Climate Change, the global frequency of tropical cyclones will likely hold steady or decrease as global warming continues. No link between warming of the oceans from increased greenhouse gases and the observed increase in the number of Atlantic named storms has been firmly established. (Note that these subtropical storms were numbered rather than named until 2004’s Subtropical Storm Nicole.)Īs explained in a post here earlier this year, improved technology has allowed the identification of weak, short-lived tropical cyclones that would have escaped detection in previous years. This ties a record set in 2007 for the most “shorties” since 1968, when the National Hurricane Center began tracking subtropical storms and counting them in seasonal totals of activity. However, nine of this year’s storms were “shorties” – named storms that lasted two days or less. The 21 named storms of 2021 were the third highest on record, behind only 2020 (30) and 2005 (28). ![]() Perhaps the most remarkable trait of the 2021 Atlantic hurricane season is that for the second year in row, the entire alphabetical list of names for storms was exhausted. Second consecutive year to run through the entire alphabet (Image credit: National Hurricane Center) 1. Preliminary track map for the 2021 Atlantic hurricane season. East Coast August 10-17.ĭigging beyond these numbers, we’ve come up with a list of the top-10 most unusual things about the Atlantic hurricane season of 2021: Figure 1. July 7-9, killing one person and causing $1.2 billion in damage, and Tropical Storm Fred, with $1.3 billion in damage during its trek up the U.S. Two other hurricanes generated more than $1 billion in damage: Hurricane Elsa, which affected the eastern U.S. Ida was blamed for 26 deaths in Louisiana, and at least 50 deaths in the Northeast.įour storms - Tropical Storm Elsa in July, Tropical Storm Fred in August, Hurricane Nicholas in September and Ida in August and September - each inflicted more than $1 billion in costs, NOAA said.One hurricane will surely get its name retired – Ida, with $64.5 billion in damage and 96 deaths, ranking as the fifth most costly weather disaster in world history, according to NOAA. ![]() Ida hit Louisiana as a Category 4 hurricane with a dangerous storm surge and strong winds, and it remained dangerous and destructive for roughly 1,000 miles, as it brought catastrophic flooding to the mid-Atlantic. hurricanes on record since 1980, according to the National Oceanic and Atmospheric Administration. Hurricane Ida alone accounts for more than $60 billion in damages - making it one of the five most costly U.S. While repairs and recovery efforts are ongoing, the 2021 Atlantic season will likely go down as one of the most expensive in history. Here are some of the things that set the 2021 season apart: Storms inflicted deaths and expensive damage With 21 named storms, 2021 ranks as the third most active year in history, according to the National Hurricane Center. The 2021 Atlantic hurricane season is now officially over, ending a period in which eight storms smacked into the U.S. Year book: All 21 named storms from the busy 2021 Atlantic hurricane season are seen in a composite image from NOAA's GOES East satellite.
