The latest update from Governor Henry McMaster and his team keeps Charleston, Horry and Georgetown counties under mandatory evacuation.
"This is still a very dangerous storm ... impossible to predict," McMaster said. "We are being prepared."
Colleton, Jasper and Beaufort county's evacuation orders have been lifted as of 3 p.m.
South Carolina Emergency Management Division officials say that between 7-15 inches of rain are expected, and two confirmed tornadoes touched down in North Myrtle Beach and Little River earlier today.
The Waccamaw River is set to crest at 15.5 feet and remain at 14 feet for a week to ten days, they said.
McMaster said that Georgetown County officials reported that the water on Front Street was a foot deep and getting deeper. He said he spoke with North Myrtle Beach Mayor Marilyn Hatley, who said water was as much as four feet deep on some parts of Ocean Boulevard.
The Governor said that there was thankfully a lack of "coincidental presence of high tides", so water was not quite as bad as expected, but there was "still plenty of it."
He said it seems the lower part of the state got off a little lighter than expected, with Horry and Georgetown counties getting hit harder than anticipated. The entire city of Georgetown was without power, he said.
"Stay inside. If you don't need to be out, don't go out," McMaster said. "Be careful and listen to local authorities ... so far there are no storm-related deaths and we want to keep it that way."
South Carolina Department of Social Services said that only 2,484 people are taking shelter among the 35 shelters available.
The state Department of Insurance warned citizens against those wishing to take advantage those in need of repairs.
"Make sure you are doing business with someone you know, make sure you see their contractor's license, and don't pay up front for any damages or repairs," said Department of Insurance director Ray Farmer. "Check their references, make sure they have liability insurance ... check with the Better Business Bureau."
McMaster said to stay tuned to find out when decisions are made to lift evacuation orders for the remaining counties.
