Tropical Storm Chantal formed off the coast of South Carolina on Saturday, July 5, as the National Hurricane Center warned of heavy rainfall across the coastal Carolinas. The center said tropical storm conditions could start Saturday evening and continue through Sunday morning.

A tropical storm watch stretches along the coast from Edisto Beach, S.C., to the South Santee River. The hurricane center said those elsewhere along the southeast coast of the United States should also keep an eye on Chantal. Chantal is expected to track slowly to the north and then northwest and move onshore in South Carolina by Sunday morning.

Tropical Storm Chantal has formed off the southeast U.S. coast. The National Hurricane Center in Miami says tropical storm warnings have been issued for portions of the Carolinas. Tropical storm conditions are expected in the affected areas later Saturday.
