There have only been two other hurricanes in the last 50 years-Andrew in ‘92 and Michael in 2018- that have made landfall in the U.S. The National Hurricane Center warns that increased hurricane intensity can cause catastrophic damage even to well-built homes, saying total roof failure and wall collapse is highly probable once hurricanes reach Category 5 status, meaning they have sustained winds of 157 mph or higher.īefore landfall, Hurricane Ian was just 2mph short of this mark. Increasingly powerful storms will have devastating effects on the places we live. Thus, some catastrophic storms like Hurricane Katrina have been omitted from this list because their wind speeds were below Category 4. This is because the current rating scale that determines what category a storm will be does not look at other factors like rainfall and flooding-which are also becoming more intense. TIME’s analysis of the frequency of Category 4 and 5 storms to hit the country, however, only takes into account hurricanes with high sustained winds. hurricane landfalls out of a total 13 in the 2010s (the Saffir-Simpson Hurricane Wind Scale counts major hurricanes as those that are Category 3 or higher) there have already been four in the last two years alone. between 2000-2010-which saw 19 hurricanes make landfall.Īnd compared to three major continental U.S. That’s nearly half the number to hit the U.S. In the span of just one year, from 2020-2021, there have been eight hurricanes to impact the continental U.S., according to NOAA data. The frequency and intensity also varies and has been changing over time. as Category 4 or 5 storms on the Saffir-Simpson Hurricane Wind Scale. This maps shows the hurricanes in the last 50 years that have made landfall in the continental U.S. coastline since 1851, of which more than 80% of those hit just three states-Florida, Texas, and Louisiana. Two others have impacted Louisiana, with the remaining hitting Texas and South Carolina.ĭata from the National Oceanic and Atmospheric Administration’s (NOAA) shows that there have been more than 300 hurricanes that have directly hit the U.S. Five of these made landfall along the Florida coastline, with Hurricane Andrew alone causing an estimated $26 billion in damages to the state in 1992. in the last 50 years-six of which have occurred since just 2017. While this storm marks the most powerful hurricane seen this season, it makes history as the ninth category 4 or 5 hurricane to hit the mainland U.S. Hurricane Ian devastated southern Florida on Wednesday afternoon when it hit as a Category 4 storm, causing intense flooding and leaving 2.5 million Floridians without power. EDT and provided by NOAA shows Hurricane Ian making landfall in southwest Florida near Cayo Costa, Fla., on Sept.
