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.

No fatalities reported in South Carolina
Ian, the first hurricane to make landfall in South Carolina since Matthew in 2016, has not caused any deaths in South Carolina, Gov. Henry McMaster said Saturday.
“Another good story for South Carolina, and we’re open for business,” he said at a news conference.
Ian barreled through South Carolina on Friday. The hardest-hit areas were along the coast from Charleston to Horry County, said Kim Stenson, director of the South Carolina Emergency Management Division. Charleston saw 6 to 8 inches of rain.
Remnants of Ian head to mid-Atlantic, Northeast
The remnants of Hurricane Ian, once a Category 4 hurricane that made multiple U.S. landfalls, are pushing up the mid-Atlantic and bringing widespread rain from Virginia to Connecticut.
Ian is now considered a post-tropical cyclone with maximum sustained winds of 35 mph.
Flood watches are in effect in Virginia and West Virginia, where up to 6 inches of rain is expected through Saturday afternoon. A wind advisory is also in effect; gusts could reach 50 mph at higher elevations.
The rain will then continue to move north. Some of the Northeast coast, especially Delaware and Long Island, could see up to 6 inches of rain over the next 48 hours.

Biden approves North Carolina emergency declaration
President Biden has declared that an emergency exists in North Carolina and ordered federal assistance to help with the state's response in the aftermath of Hurricane Ian.
"The President’s action authorizes the Department of Homeland Security, Federal Emergency Management Agency (FEMA), to coordinate all disaster relief efforts which have the purpose of alleviating the hardship and suffering caused by the emergency on the local population," the White House said in a statement released early Saturday.
FEMA is authorized to identify, mobilize and provide equipment and resources to help the recovery efforts on the ground.
"Deanne Criswell, Administrator, Federal Emergency Management Agency (FEMA), Department of Homeland Security, named John F. Boyle as the Federal Coordinating Officer for Federal recovery operations in the affected areas," said the White House."
Ian’s winds have come down to 50 mph as the storm continues to move north as a post-tropical cyclone.
Ian will continue to weaken as it moves north, and will bring heavy rainfall in short periods of time through the morning hours, prompting flood watches to be issued from North Carolina to West Virginia.
‘It’s a different Sanibel,’ mayor says
Sanibel, Florida Mayor Holly Smith said that her city will not be the same following Hurricane Ian's catastrophic impact.
Smith said she was on the island for four hours Friday and witnessed the devastation firsthand.
"Unless you're on the ground, you really can't take in the gravity of what we experienced. It's a different Sanibel," Smith told ABC News Live Prime.
Smith said that she was checking in on 300 residents and that it was very important to make contact.
"As far as we know at this point, the number of fatalities recorded are four,'' Smith said.
"This is going to be a very long recovery process," Smith added of the efforts to get everybody off the island and to safety. "It's not habitable."
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.
