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.
As of the 2 a.m. ET advisory this morning, Ian continues to maintain its hurricane status.
However, it has weakened to a 75 mph Category 1 hurricane and is expected to become a tropical storm later this morning before emerging off of Florida’s east coast.
Ian’s new track will be issued and updated again at 5 a.m. ET.

Florida's electric providers said more than 2.3 million customers were without power at about 2 a.m. local time.
Florida Power & Light, the state's largest provider, reported more than 1.1 million outages for its 5.7 million customers.
“Hurricane Ian’s catastrophic winds will mean parts of our system will need to be rebuilt -- not restored,” the company said on Twitter late Wednesday. “Be prepared for widespread, extended outages as we are assessing the damage. We are already at work restoring power where we can do so safely.”

Portions of Fort Myers are under up to 4 feet of water, the city said late Wednesday night, and residents are being told to stay inside as first responders try and assess the damage from Hurricane Ian.
"We need to ensure that the roads are clear so that our first responders and our assistance crews can go out there and help everyone that needs us," the city wrote on Twitter. "PLEASE, please, please stay inside."
Jacksonville International Airport has canceled all flights for Thursday and the terminal will be closed.
