Atlantic City, NJ – A tsunami alert along the New Jersey coast is rare, but even a modest surge can flood barrier islands and back bays within minutes, especially during high tide.
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 Atlantic City, Cape May, Long Beach Island, and Sandy Hook should move inland immediately. Evacuate barrier islands using major routes like the Garden State Parkway and Route 9, avoiding low-lying access roads that can flood quickly.
A Tsunami Advisory signals strong currents and hazardous waves. While not a full evacuation, conditions near beaches, inlets, and marinas can become life-threatening. Stay out of the water and away from boardwalks, piers, and docks.
A Tsunami Watch means a tsunami is possible following a distant earthquake. Residents should review evacuation routes, prepare emergency kits, and be ready to act quickly if alerts escalate.
An Information Statement indicates no immediate threat.
New Jersey’s barrier islands and coastal bays allow water to move inland fast, particularly around areas like Barnegat Bay. Residents should enable emergency alerts, monitor local officials, and be ready to move inland immediately if a warning is issued.
