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.

Desolation, and relief, in Key West
Key West did not escape hardship, but in Ian's wake, many Key West residents have expressed relief that the coastal city hadn't endured far worse.
The path of the then-Category 4 hurricane veered west of Key West, sparing it the strongest of the storm's impact. Flooding was reported in nearly 100 apartments. Though the city suffered no casualties or uptick in emergency room visits, Alyson Crean, a public officer with the Key West Fire Department, told ABC News. The city largely returned to normal on Friday, as businesses and schools reopened.
The mix of desolation and relief in Key West embodies the range of fates across Florida, where some communities escaped largely unscathed while others saw tragedy.
"We were relieved when we saw that the storm was turning a different way," Jennifer McComb, the chief executive at the Community Foundation of the Florida Keys, told ABC News. "For a while, it looked like it could've been a direct hit."

A search for a survivor told on social media
As Hurricane Ian was bearing down on southwestern Florida Wednesday, Beth Booker received photos and videos showing Ian's storm surge starting to fill her mother's Fort Myers home.
Then, shortly after the storm made landfall in Florida, the updates stopped.
Unable to communicate with her mom, Carole McDanel, any longer, Booker turned to Twitter, using the hashtag #GetCaroleHome and asked her followers for help.
Some 24 hours later, Booker tweeted the news that McDanel had been found.

Ian death toll in Florida at least 33: Analysis
There have been at least 33 storm-related deaths due to Ian in Florida, ABC News has determined based on information from the Florida Medical Examiners Commission and inquiries with local officials and authorities.
That includes 16 deaths in Lee County, six in Charlotte County, four in Volusia County, three in Collier County, two in Sarasota County, and one each in Lake and Manatee counties.
Earlier Friday, Florida Gov. Ron DeSantis said there were 21 deaths from Ian, of which 20 were unconfirmed because they were spotted during search and rescue operations and crews were told to prioritize those found alive and still trapped.
The Florida Department of Law Enforcement said Friday evening that there are 10 confirmed deaths attributed to Ian across in Lake, Sarasota, Manatee, Volusia and Collier counties. The causes of death were primarily drownings, as well as two vehicle accidents and a roof accident. The tally, confirmed by the Medical Examiners Commission, does not include any fatalities from hard-hit Lee or Charlotte counties.
It is unclear whether the state's figures overlap with ABC News' analysis.

More than 1.68 million people are still without power in Florida.
Gulf Coast, Tampa Bay area particularly vulnerable to hurricanes, expert says
Tropical Storm Ian is marching toward the Gulf Coast of the U.S., a region quite vulnerable to hurricanes.
The underwater geology of the Gulf of Mexico is what makes the Gulf Coast particularly unguarded to the massive influx of seawater, said Michael Brennan, acting deputy director of the National Hurricane Center, according to an article on Inside Science.
The symmetry of the Gulf of Mexico, with its shallow, sloping continental shelf, allows the storm surge to be pushed even higher onto land, Brennan told the outlet.
Because the land around the Gulf Coasts is typically flat, that exacerbates the flooding even more and allows the storm surge to travel farther inland, Brennan said.
"Of all of the hazards of hurricanes --- winds, rain, storm surges –-- surges are what can cause the largest loss of life," Brennan told Inside Science.
The Tampa Bay-St. Petersburg area, one of the regions bracing for Ian, is especially vulnerable to storm surge flooding but has avoided a direct hit from a strong hurricane since 1921.
