"A more tropical air mass starts to stream northward Sunday night into Monday morning,“ the National Weather Service said in a forecast update Saturday afternoon. ”There will also be some moisture moving northward from what will be left of Tropical Storm Chantal as it is expected to dissipate over North Carolina Sunday night into Monday morning."

The storm's center was located about 65 miles east of Charleston, South Carolina, on Saturday night, and 120 miles south of Wilmington, North Carolina.

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.
