BLADENBORO, N.C. – Thousands of coastal residents remained on edge Sunday, told they may need to leave their homes because rivers still are rising more than a week after Hurricane Florence slammed into the Carolinas. About 6,000 to 8,000 people in Georgetown County, South Carolina, were told to be prepared to evacuate ahead of a “record event” of up to 10 feet of flooding expected from heavy rains dumped by Florence, county spokeswoman Jackie Broach-Akers said.
