Lee County, which encompasses Fort Myers, accounts for most of the fatalities.
The remnants of Ian are charging up the East Coast on Saturday after making landfall as a Category 1 hurricane in South Carolina on Friday afternoon.
The monster storm made its first U.S. landfall on Wednesday on Florida's west coast as a powerful Category 4 hurricane, shredding homes with ferocious winds topping 150 mph. Florida's death toll has climbed to at least 81, according to information from local officials.
Jacksonville Mayor Lenny Curry announced Wednesday evening that the city is closing Atlantic, Neptune and Jacksonville beaches ahead of Hurricane Ian’s impact on the area.
“We will reopen as soon as it’s safe for citizens,” Curry tweeted.
Hurricane Ian has been downgraded to a Category 2 storm as of a 9 p.m. ET update, with winds now at 105 mph.

Lee County has received more than double the number of 911 calls it typically receives amid Hurricane Ian, according to Sheriff Carmine Marceno, as first responders have suspended their emergency response during the major storm.
"We hear your calls and are aware that Hurricane Ian was a powerful and devastating weather event," Marceno said in a social media post Wednesday evening. "We want to get to you. We want to save you. As soon as safely possible, our assets are ready to deploy to come to your aide."
Ben Abes, Lee County's public safety director, said current conditions, including flooding, make it "impossible" for first responders to go out. He said the county is tracking 911 calls and prioritizing them once first responders are able to act after the hurricane passes.
"We are aware of a number of calls of people who are stranded due to high water," he said during a press briefing Wednesday evening. "This is a scary situation. We urge you not to panic."
Lee County, which is home to hard-hit Fort Myers, Sanibel and Bonita Beach, issued a countywide curfew Wednesday evening due to the storm that is in effect until further notice.
