A flood watch was in effect July 7 for several states, including Virginia, Maryland, Delaware, New Jersey and Pennsylvania. "Storm total rainfall of 2 to 4 inches, with local amounts up to 6 inches, is expected," the Weather Prediction Center said in a 5 a.m. ET update. "An elevated risk for flash flooding will continue."

Dozens of residents needed to be rescued from rising water, and hundreds of roads were closed as the storm moved over the central part of North Carolina.

Tropical storm warnings were extended up to Surf City, North Carolina, ahead of Tropical Storm Chantal's landfall in South Carolina early Sunday.
