"We do not want to risk one South Carolina life in this hurricane," the governor told a press conference. "We're liable to have a whole lot of flooding."
Hurricane Florence has the potential to bring catastrophic flooding to areas of the eastern United States already soaked by heavy rain and may be the strongest storm to hit the region in decades.
A Category 4 on the five-level Saffir-Simpson hurricane wind scale, Florence was 525 miles south-southeast of Bermuda and the center of the hurricane was forecast to pass between Bermuda and the Bahamas on Tuesday and Wednesday, the National Hurricane Center (NHC) said in its 5:00 pm (0230 IST) advisory.
Florence is currently moving west at around 13 miles per hour. "Florence has continued to rapidly strengthen," the NHC said. "Florence is expected to be an extremely dangerous major hurricane through Thursday."
President Donald Trump tweeted out a message to residents in the storm's path, urging them to heed the warnings of state and local officials.
"To the incredible citizens of North Carolina, South Carolina and the entire East Coast - the storm looks very bad!" wrote the president, who cancelled a planned rally Friday in Jackson, Mississippi, in light of the approaching storm.
