A Flood Watch remains in effect through late Sunday night for much of the southeastern North Carolina coast and northeastern South Carolina, as heavy showers are expected to deliver 2 to 4 inches of rain, with isolated areas receiving up to 6 inches. The National Weather Service has warned that flash flooding could develop rapidly, particularly in low-lying neighborhoods and urban areas with poor drainage.
The heavy rainfall is being caused by a coastal trough, which is pushing repeated rounds of showers and occasional thunderstorms onshore from Georgetown, South Carolina, to Wilmington, North Carolina. This includes cities like Myrtle Beach, North Myrtle Beach, Conway, Loris, Southport, Oak Island, as well as inland communities such as Whiteville and Kingstree.
Flood-prone roads near creeks, rivers, and tidal marshes—including stretches of U.S. 17—are at risk of becoming impassable during periods of heavy rain. The combination of already saturated ground and overnight downpours raises the potential for street flooding, especially during the Monday morning commute.
Residents are urged to avoid driving through standing water, secure any loose outdoor items, and stay updated on local alerts. While the heaviest rainfall is expected to taper off before daybreak Monday, lingering high water could still result in road closures and travel disruptions into the morning hours.
