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.

Satellite images show that the storm should weaken as it nears the coast sometime overnight Sunday or early Monday. Even though the storm will weaken as it approaches land, it will still bring tropical storm conditions near the coast throughout Monday.
