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 is expected to strengthen off the Southeast coast, and while this system will bring rain, gusty winds and rip currents, it's expected to be short-lived. Tropical storm warnings have just been issued for parts of the Carolina coast.
