Charleston, SC – A tsunami alert along the Carolina coast is uncommon, but low-lying beaches and barrier islands can see rapid flooding within minutes if a warning is issued.
According to the National Weather Service and NOAA, a Tsunami Warning means dangerous coastal flooding and strong currents are expected or already occurring. Residents in coastal areas like Charleston, Myrtle Beach, Wilmington, and the Outer Banks should move inland immediately. Evacuate barrier islands and avoid routes like U.S. 17, NC-12, and SC-703 that can flood quickly or become gridlocked.
A Tsunami Advisory signals strong currents and dangerous surges. While not a full evacuation, conditions near beaches, piers, and inlets can become life-threatening. Stay out of the water and away from docks and low-lying shoreline areas.
A Tsunami Watch means a tsunami is possible after a distant earthquake. This is the time to review evacuation plans, gather essentials, and prepare to move if alerts escalate.
An Information Statement indicates no immediate threat.
The Carolina coastline is especially vulnerable during high tide, when water can push farther inland. Residents should enable emergency alerts, monitor local officials, and be ready to act immediately if a warning is issued.
