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.

Chantal downgraded to a tropical depression over the weekend and was moving northeast through Virginia early morning Monday as flash flood threats continued near the storm, forecasters say. There have been no local impact in Louisiana.
