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.

Potential impacts include damage to porches, awnings, and mobile homes, scattered power outages, and road closures due to debris.

Tropical Storm Chantal was forecast to make landfall in South Carolina early Sunday, bringing heavy rainfall to the Carolinas. Chantal became a tropical storm Saturday morning about 150 miles off the coast of South Carolina, prompting tropical storm warnings for portions of the Carolinas.
