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.

16 feet of storm surge possible
A whopping 16 feet of storm surge is possible around Fort Myers.
Up to 11 feet of storm surge is forecast for Naples while a maximum of 10 feet is expected for the Sarasota area.
"Our biggest concern as we wait for this storm to make landfall is storm surge," FEMA Administrator Deanne Criswell warned Tuesday. "In 2018, when Hurricane Michael impacted the Florida Panhandle, there were five recorded fatalities as a result of storm surge."

Tropical Storm Ian will rapidly intensify Sunday, forecasts show
Ian remains a tropical storm with winds of 50 mph, but the storm system is expected to rapidly intensify on Sunday as it moves over warm waters in the Caribbean Sea, according to the National Hurricane Center.
The seawater currently carries very favorable conditions for strengthening over the coming days, with temperatures between 85 and 90 degrees Fahrenheit -- the perfect temperatures for fueling a powerful storm as it stays over open water.
Ian is expected to strengthen to a hurricane by Sunday night and into a major hurricane later Monday night as it passes by Cuba.
The NHC currently forecasts Ian to strengthen into a major Category 4 hurricane on Tuesday in the Gulf of Mexico as it heads toward Florida.
Ian is expected to make landfall on the west coast or the panhandle of Florida on Wednesday or Thursday.
Some weakening could occur before the storm system makes landfall, possibly dipping below major hurricane status before impacting coastal communities.
A hurricane warning is currently in effect for the western portion of Cuba, where flooding rains and major storm surge are forecast.
