WILMINGTON, N.C. -- Tropical Storm Chris has prompted warnings to swimmers and surfers in South Carolina and is expected to become a hurricane overnight. The National Weather Service does not have any tropical storm or hurricane warnings in effect, but forecasters said swimming could be dangerous in South Carolina's Georgetown and Horry counties.

The weather service said current conditions could create currents than can sweep swimmers and surfers into rip currents or piers and jetties.
