Hurricane forecasters have their eyes on a tropical disturbance brewing off the coast of the Southeast United States that has a moderate chance of formation into a cyclone − but could become a tropical or subtropical depression as early as the Fourth of July holiday weekend.

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.

Forecasters are monitoring a developing low pressure that could bring tropical weather to Wilmington. See the latest radar map.
