Hurricane Ian updates: Florida death toll climbs
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.

FEMA: 'Do not underestimate' Ian
Federal Emergency Management Agency Administrator Deanne Criswell warned Tuesday, "Floridians are going to experience the impacts from the storm for a very long time."
"Our biggest concern as we wait for this storm to make landfall is storm surge," Criswell said. "In 2018, when Hurricane Michael impacted the Florida Panhandle, there were five recorded fatalities as a result of storm surge. So therefore, if people are told to evacuate by their local officials, please listen to them. The decision you choose to make may mean the difference between life and death."
President Joe Biden on Tuesday urged residents to "evacuate when ordered."
Biden said he spoke to the mayors of Tampa, St. Petersburg and Clearwater Tuesday morning and told them to "contact me directly" for "whatever they need."
Criswell said a search and rescue coordination group has been activated, including members from FEMA's urban search and rescue teams, the Coast Guard, the Department of Defense and the Department of the Interior.
The Red Cross has established 29 shelters and is prepared to open 60 more shelters if needed, she said.
Criswell stressed, "To those who may be watching at home, get ready and do not underestimate the potential that the storm can bring."
