FEMA Administrator Deanne Criswell stressed Wednesday the danger of water as Hurricane Ian approaches.
She urged Floridians to never drive through floodwaters, noting a car can be carried away in just a few inches of water.
“From coastal storm surge to inland flooding, the majority of the state of Florida is in Ian’s crosshairs,” she said.
18 feet of storm surge possible
Up to 18 feet of dangerous storm surge is forecast along Florida’s Southwest coast, including Englewood, Bonita Beach and Charlotte Harbor.
FEMA Administrator Deanne Criswell warned Tuesday that her biggest concern with Ian was storm surge.
"In 2018, when Hurricane Michael impacted the Florida Panhandle, there were five recorded fatalities as a result of storm surge,” she noted.
Gov.: Treat storm like tornado approaching your home
Florida Gov. Ron DeSantis warned Wednesday morning that Ian could potentially make landfall as a Category 5 hurricane.
“This is a powerful storm that should be treated like you would treat a tornado approaching your home,” he said. “This one has just strengthened and strengthened, and it is the real deal. So, it is going to do a lot of damage, so people should be prepared for that.”
More than 200 shelters are open in South Florida, he said.
Twenty-six states, including New York and New Jersey, have sent support to Florida, he said.
