Only four hurricanes have ever hit the mainland U.S. with winds stronger than Ian’s and all were deadly category 5 storms — the most powerful on the Saffir-Simpson scale.

Those terrors were the Labor Day hurricane of 1935 that tore through Miami; Camille that struck the Gulf Coast near Mississippi in 1969; Andrew in 1992 and Michael in 2018. Andrew and Michael — which both hit Florida — are in the top 10 most expensive US storms.

Neither of the top two costliest storms were category 5 however: Katrina landed as a category 3, causing $186.3 billion in today’s dollars and Harvey was a category 4 when it hit Texas, bringing $148.8 billion in damages.

Camille hit what was then a sparsely populated area of the Gulf and would have caused $11.3 billion in damages in today’s dollars, according to the National Centers for Environmental Information. Michael also hit a relatively open area of the Florida Panhandle, causing $29 billion in damages. Andrew struck near Miami, with $55.9 billion of devastation. The 1935 Labor Day storm caused $129 million in damages, an inflation-adjusted figure based on an estimate from the National Oceanic and Atmospheric Administration.

More about Hurricane Ian

The difference between storms like Michael and Camille is that Ian is going to hit a fairly built-up area, said Dan Pydynowski, a meteorologist at commercial forecaster AccuWeather Inc.

“This one is hitting an area where you have a lot of buildings and infrastructure,” he said. “And a lot of expensive real estate. Michael was devastating but it did not hit a hugely populated area.”
