Chantal,  the first tropical storm of the hurricane season to make landfall in the US brings risk of torrential rain to North Carolina and Mid-Atlantic states.

What was once Tropical Storm Chantal has weakened, but it is still triggering heavy showers and thunderstorms in the central part of North Carolina.

A tropical storm warning remains in effect from the South Santee River, South Carolina, to Surf City, North Carolina, including Myrtle Beach, South Carolina. Peak winds in the area are forecast to be 20 to 30 mph with gusts up to 45 mph. About an hour after making landfall, Chantal had weakened, with sustained winds then up to 50 mph.
