Tropical Storm Chantal formed in the Atlantic on Saturday morning and is projected to reach South Carolina and North Carolina 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. 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.

The storm isn’t a significant threat to land, but could drench parts of the Southeast and create risky beach conditions through the weekend.
