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.

A caravan of utility trucks is making its way from several states toward the parts of Florida most battered by Hurricane Ian to restore power after the worst of the storm has passed, Florida Gov. Ron DeSantis announced during a news conference Wednesday afternoon.

"We have a massive, massive mobilization," DeSantis said, adding that workers are coming from other southern states accustomed to hurricane cleanup, such as Texas and Louisiana.

More nearly 1.5 million customers in Florida were without power Wednesday as Ian made landfall near Fort Myers.

Ian continued to batter a large swath of Florida at 6:15 p.m. ET, with life-threatening storm surge all along the southwest coast — up to 12 feet in some places, DeSantis said.

Downtown Naples was reportedly completely flooded due to record storm surge, and while there were also reports of structural damage in Lee County, DeSantis said.

"This was a top five hurricane to ever hit the Florida peninsula," the governor said.

DeSantis said that devastating inland flooding was inundating much of the regions experiencing hurricane conditions, as well.

DeSantis has declared a major disaster in the state.
