Annapolis, MD – A tsunami alert in Maryland is rare, but water can surge quickly into the Chesapeake Bay and coastal inlets, putting low-lying communities at risk within minutes of a warning.
According to the National Weather Service and NOAA, a Tsunami Warning means dangerous flooding and strong currents are expected or already occurring. Residents in Ocean City, Annapolis, Baltimore’s Inner Harbor, and communities along the Chesapeake Bay should move to higher ground immediately. Avoid low-lying roads such as Coastal Highway (MD-528) in Ocean City and waterfront routes around the Bay that can flood rapidly.
A Tsunami Advisory signals powerful currents and hazardous surges. While not a full evacuation, conditions near beaches, marinas, and tidal rivers can become life-threatening. Stay out of the water and away from docks, piers, and shoreline areas.
A Tsunami Watch means a tsunami is possible following a distant earthquake. Residents should review evacuation plans, prepare emergency kits, and monitor alerts closely.
An Information Statement indicates no immediate threat.
Because the Chesapeake Bay can funnel water inland, even smaller surges may travel farther than expected. Residents should enable emergency alerts, follow local officials, and be ready to act immediately if warnings are issued.
