Wilmington, N.C. – Heavy rainfall is expected to swamp the Carolina coast this afternoon, with flash flooding likely in parts of southeast North Carolina and northeast South Carolina through late Tuesday night.

According to the National Weather Service in Wilmington, a flood watch is in effect for Brunswick and New Hanover counties, where 2 to 4 inches of rain are expected, with localized amounts exceeding 5 inches. The heaviest rain is forecast from Tuesday afternoon into the overnight hours, bringing the risk of rapidly rising streams and flooded roadways.

In North Carolina, Wilmington, Oak Island, and Burgaw are in the primary impact zone. South of the state line, Myrtle Beach, Georgetown, and Florence also face flash flood risks. Urban areas and low-lying fields are especially vulnerable, and emergency officials urge drivers to avoid flooded roads and heed barricades. “Turn around, don’t drown” remains the key safety message.

Drivers should expect delays on U.S. Highway 17 and other coastal routes, while residents are encouraged to charge devices, check storm drains, and monitor local alerts. Schools and businesses may also face early dismissals if rainfall rates increase.

The flood watch remains in effect through Tuesday night. Additional alerts could be issued if rain bands intensify or shift inland.
