Coastal areas could see 6 to 10 inches of rain by Friday and up to 15 inches in isolated areas, the National Weather Service in Wilmington, North Carolina reported Sunday night.
The Waccamaw River could reach minor or moderate flood stages if these rainfall amounts occur, the National Weather Service said.
Waccamaw River levels are currently at about 8.53 feet.
Minor flood stage is 11 feet and moderate flood stage is 12 feet.
That’s significantly lower than the record set by Hurricane Florence last year, when the Waccamaw crested at 21 feet.
After Hurricane Matthew, the Waccamaw reached 19 feet.
At minor flood stage, yards and roads will flood along the river and swamps.
At moderate flood stage, river flooding will impact some homes in the Lees Landing, Riverfront South, Pitch Landing and Savannah Bluff communities.
No flooding is forecast for the Pee Dee, Little Pee Dee River or Black River.
However, the Black River in North Carolina could see flooding due to Hurricane Dorian as well as the Cape Fear and Northern Cape Fear Rivers.
