Hurricane Ian has strengthened, with winds now at 85 mph, as it continues to move northward off the east coast of Florida.

The forecast track has shifted a little farther north with the latest advisory at 11 p.m. ET, putting cities like Myrtle Beach, S.C., in the storm's path for worse impacts, while less impact could be seen in Charleston.

Wind Gusts up to 90 mph are possible in Myrtle Beach on Friday afternoon, as Ian is expected to make landfall toward the south. Much of Georgia to the Carolinas will experience wind gusts over 50 mph.

Despite water receding in Fort Myers following Hurricane Ian's destructive path across Florida, 80% of the city is still without power, while 70% is without water, Mayor Kevin Anderson told ABC News Live Prime.

Anderson said the most important thing is to get electricity and water back up and running for residents, especially since it's still hot and humid in the area and people need air conditioning and water.

"Tomorrow, we're expecting the delivery of the pods with the water and food and ice and we'll be setting up delivery stations," he said. "Again, the problem is it's very, very difficult to live here without air conditioning."

Fort Myers has performed about 200 rescues and counting, according to the mayor.

"The crews were out and they're probably still out there working now, getting the roads cleared and getting the roads where they're traversable so that emergency vehicles can respond," Anderson said.

Eva Neocleous, her mother, Aurora, and dog, Primi, waited more than 24 hours to get rescued from their Fort Myers home in the aftermath of Hurricane Ian.

The family first called for help at 11 a.m. on Wednesday, but conditions were too dangerous for first responders at the time. Nobody came until the Cajun Navy pulled them out around 12:30 p.m. Thursday.

Neocleous said the ordeal was terrifying: "I thought I was going to die right there."

There have been more than 700 confirmed rescues in the aftermath of Hurricane Ian slamming Florida, Gov. Ron DeSantis said Thursday.

The Sanibel Causeway, which suffered significant damage in the storm, will most likely need to be rebuilt entirely, he said.

There were more than 2.3 million customers without power in the state just before 9 p.m. ET Thursday.

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.
