Tropical Storm Chantal formed in the Atlantic on Saturday morning and is projected to reach South Carolina's coast on Sunday, the National Hurricane Center said.

A tropical storm watch stretches along the coast from Edisto Beach, S.C., to the South Santee River.

Chantal is expected to track slowly to the north and then northwest and move onshore in South Carolina by Sunday morning.
