On the heels of Tropical Depression Chantal, climatologists are warning that storms like it could become more common.

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."

Tropical Storm Chantal has now been downgraded to a tropical depression after making landfall early Sunday. The storm made landfall near Litchfield Beach, South Carolina, according to the National Hurricane Center. Its maximum sustained winds have since decreased to 35 mph. Chantal is currently moving to the north at 9 mph.
