Tropical Storm Chantal has been downgraded to a tropical depression but is raising concerns of flash flooding in central North Carolina and south-central Virginia.

Two North Carolinians are missing after they paddled a canoe onto a lake as Tropical Storm Chantal lashed the southern states over the weekend.

The storm flooded roads, downed trees and stranded residents across the central part of the state. It is headed northeast toward Washington, D.C., and Maryland.
