A new round of evacuations was ordered in South Carolina as the trillions of gallons of water dumped by Hurricane Florence meanders to the sea, raising river levels and threatening more destruction.

With the crisis slowly moving to South Carolina, emergency managers on Friday ordered about 500 people to flee homes along the Lynches River. The National Weather Service said the river could reach record flood levels late Saturday or early Sunday, and shelters are open.

Officials downstream sounded dire alarms, pointing out the property destruction and environmental disasters left in Florence's wake.

"Although the winds are gone and the rain is not falling, the water is still there and the worst is still to come in the Pee Dee," South Carolina Gov. Henry McMaster said Friday, referring to the eastern part of the state.

Georgetown County Administrator Sel Hemingway warned the area may see a flood like it has never seen before. "We're at the end of the line of all waters to come down," he said.

In North Carolina, where about 100 people were evacuated by boat and air after the Cape Fear River breached a levee and flooded the town of Kelly on Thursday night, a familiar story was unfolding as many places that flooded in Hurricane Matthew in 2016 were once again inundated.
