Tropical Storm Chantal has formed off the southeastern U.S. coast. The National Hurricane Center in Miami says tropical storm warnings have been issued for portions of the Carolinas.

Tropical Storm Chantal is forecast to bring heavy rains as it moves inland across northeastern South Carolina on Sunday. Tropical storm warnings were issued for portions of the two Carolinas, the National Hurricane Center in Miami said.

Downpours will sweep central Texas for another day, complicating rescue efforts after extreme flooding in the region left at least 82 people dead and scores missing.

Wildfires can damage local vegetation and change soil characteristics, making the area more vulnerable to flash floods.
