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 brought heavy, flooding rain and dangerous beach conditions to the Carolinas over the weekend, setting off life-threatening flash flooding Sunday in central parts of North Carolina that killed at least one person and prompted dozens of rescues.
