These are the most costly hurricanes in US history

The southeastern US has been hit by a pair of hurricanes in quick succession over recent weeks

Hurricane season is in full force, with the U.S. dealing with the aftermath of a pair of damaging and deadly hurricanes in quick succession.

The southeastern U.S. has been hit by back-to-back hurricanes in recent weeks, with Hurricane Helene bringing devastating flooding to parts of North Carolina and Tennessee two weeks ago, while Hurricane Milton spawned a number of damaging tornadoes even as Florida's Gulf Coast was spared the worst of its storm surge when it made landfall Wednesday.

The economic toll of those two hurricanes is still being tabulated as insurance claims come in amid the cleanup while businesses and schools return to normal operations.

While the 2024 hurricane season's storms to date have brought both a human and economic toll to impacted areas, they fortunately haven't ranked among the costliest hurricanes in U.S. history. Here's a look at the most economically costly hurricanes in U.S. history.

Hurricane Sandy impacted the entire Atlantic Coast and 24 states, including those near the Great Lakes, when it hit in 2012, and brought severe flooding and storm surge to New York and New Jersey.

Hurricane Ida made landfall in Louisiana in 2021 as one of the strongest storms to ever hit the state. It went on to bring tornadoes and catastrophic flooding as it made its way from the Gulf Coast inland towards the Northeast.

Hurricane Ian struck Florida in 2022 and was the state's deadliest since the 1935 Labor Day hurricane. The storm went on to inflict more damage in the Carolinas and Virginia.
