Ian was set to make landfall Friday afternoon on the coast of South Carolina after strengthening late Thursday into a Category 1 hurricane. It will then move inland across the state and into North Carolina by Saturday.
Officials in Florida, meanwhile, were assessing the damage and continuing search and rescue efforts after Ian slammed into the Fort Myers area on Wednesday as a Category 4 storm. There were 21 deaths, but Florida Emergency Management Director Kevin Guthrie said Friday that only one was confirmed as a result of the storm. Officials were still evaluating the cause of the 20 other deaths.
There had been 700,000 rescues as of Friday morning, officials said. Meanwhile, 1.9 million customers were still without power across the state, and Lee County is without water after a main break.
"There's been really a Herculean effort," Gov. Ron DeSantis said Friday morning of crews' work to restore power, assess damage and rescue residents.

Death toll likely to grow in Florida
The destruction left behind by Ian has made it difficult to get an accurate assessment of the loss of life, but there are already reports of 21 deaths, officials said Friday morning.
State officials said only one of these deaths, in Polk County, was confirmed as a result of the storm, and authorities were still evaluating the cause of the 20 other deaths: 12 were in Charlotte County and eight in Collier County.
But local officials in these areas were also reporting deaths:
Sanibel Island officials reported two deaths on Thursday.
In Lee County, which includes the island of Cayo Costa near Cape Coral where the storm made landfall, at least five deaths were confirmed, Sheriff Carmine Marceno told CNN.
In Deltona, about 30 miles northeast of Orlando, a 72-year-old man died after falling into a canal while using a hose to drain his pool in the heavy rain, the Volusia County Sheriff's Office said.
In Sarasota County, the sheriff's office reported two deaths related to the hurricane.
Hurricane Ian tracker
After slowly moving across Florida, Hurricane Ian gained new strength over the Atlantic Ocean on Thursday before wreaking havoc on South Carolina, Georgia and more states along the East Coast. Check here for the latest updates on the storms strength and track where it's headed next.
As of 8 a.m. Friday, Ian was about 105 miles south-southeast of Charleston, and was moving north at 9 mph with maximum sustained winds of 85 mph, the hurricane center said.
In Charleston, powerful wind gusts and rain as Ian approached
Heavy rains and tropical storm conditions had already reached the coasts of Georgia and the Carolinas by Friday morning, where life-threatening storm surge and hurricane conditions were expected to develop. Rainfall of up to 8 inches threatened flooding from South Carolina to Virginia, the National Weather Service reported.
Meteorologists were expecting conditions to steadily deteriorate across Charleston on Friday morning, when Ian was located 105 miles south-southeast of the coastal city with 85 mph winds. Traffic had cleared the streets, muting the typically bustling morning commute ahead of the storm.
Some areas had already received between 2 and 3 inches of rain by 8 a.m., and "quite a bit of flooding" had begun inundating downtown Charleston as heavy rain fell amid rising tide levels, said Steven Taylor, a lead meteorologist at the National Weather Service in Charleston.
Wind gusts were observed along the Charleston County coast at 50 to 60 mph and the area could see between 4 to 7 feet of flooding Friday, Taylor said. "We recently had a wind gust as high as 66 mph on the south end of Folly Beach and winds continue to increase across the area," Taylor told USA TODAY.
Ian's center is expected to travel northeast of Charleston by Friday afternoon, and forecasters anticipate weakening of the storm as it moves into North Carolina.
Island forecast: A look at Kiawah, Hilton Head and Pawleys
Kiawah Island: Located about 26 miles south of Charleston, the island could see up to 1.5 inches of rain throughout Friday until Ian shifts to the north, said NWS Charleston meteorologist Douglas Berry. Gusts were ranging between 35 and 45 mph Friday morning, but he said the risk of flooding would be worse in Charleston and right along the coast.
The island's location on Ian's west side and an offshore flow - when air moves from land to sea - could lower Kiawah Island's tides, resulting in minor possible coastal flooding issues through Friday afternoon. There are no current flood advisories for the island.
Hilton Head Island: Tropical storm conditions were expected along the island, which is about 97 miles southwest of Charleston. The popular tourist destination could see up to 2 inches of rain Friday, with hurricane conditions possible. A high surf advisory, flood watch and hurricane and storm surge warnings were in effect Friday morning.
Pawleys Island: Gusts up to 100 mph could be in store for Pawleys Island, located 73 miles north of Charleston, said NWS Wilmington meteorologist Jordan Baker. The island is under both storm surge and hurricane warnings. "Wind is certainly a big issue this time, and we're watching the surge," Baker told USA TODAY. "That area and could see inundation up to 4 to 7 feet."
Fort Myers Beach 'is gone' after Hurricane Ian damage
Fort Myers Beach took the brunt of Hurricane Ian's assault on Florida's coastline. The Category 4 storm sent 150 mph winds and a towering storm surge tearing through the town's center. On Thursday, residents began to see what could be salvaged from the wreckage.
"I think mine is going to be a total loss," Joy McCormack said as she stood across the road from a stretch of mobile homes, townhouses and condos that were knee-deep in flood waters. "It's the only house I have and if it's gone…" She trailed off.
For Mitch Stough and his brother, Fort Myers Beach was their livelihood. Now, it's been utterly destroyed. Stough worked at the landmark Lani Kai resort and said the storm surge stripped the vacation spot's first floor to its structural elements.
"There's nothing there," Stough said. "Fort Myers Beach is gone." Read more here.
