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 formed on Saturday as it slowly moved in the Atlantic toward the Carolinas, according to the National Weather Service.

Those with holiday weekend plans to hit the North Carolina coast may want to think twice as Tropical Storm Chantal approaches. The storm, which was named Saturday morning, is expected to make landfall north of Charleston on Saturday and hit North Carolina on Sunday,
