Developing Coastal System Threatens State with High Winds, Rain, and Coastal Flooding
The state is preparing for a range of coastal and inland impacts, with the timing and severity dependent on the final storm track. The exact path of the storm is uncertain, but the storm will likely bring strong winds, flooding, and beach erosion to many parts of Maryland—especially along coastal and bayfront areas. State and local agencies remain on heightened alert, and Marylanders are urged to stay informed and prepared as the weekend progresses.
Impacts: Flash flooding, including possibly significant flooding, will be the primary threat with storms today, in addition to potentially damaging wind gusts.
Winds: Gusts up to 55 mph are possible along coastal zones and the Chesapeake Bay shoreline, with potential to extend into central Maryland.
Coastal and Tidal Flooding and Erosion: Moderate to major coastal flooding is expected on Sunday.
The highest water levels are expected along the Atlantic coast and across the lower Chesapeake Bay and tidal rivers.
Onshore winds and elevated seas will heighten the risk of tidal flooding in low-lying coastal, bayfront, and riverine areas.
Wave heights through Sunday night may exceed 12-14 feet, with potentially significant beach erosion and wash-ups from waves.
Rain and Flooding: Several inches of rain late Saturday night into Sunday—possibly extending into Monday—may lead to small stream, creek, and river flooding, particularly in low-lying and poorly drained areas.
Power and Infrastructure: The combination of wind and saturated soils raises the possibility of isolated power outages, tree damage, and downed lines.
Actions to Take:
Avoid unnecessary travel during peak storm periods, particularly along vulnerable coastal and low-lying routes especially along the eastern seaboard;
Secure outdoor furniture, boats, and other objects that may become projectiles in high wind;
Be prepared for temporary power outages — keep flashlights, batteries, and basic supplies handy;
Monitor local river gauges, and always avoid driving through flooded roadways; and
Stay alert by following updates from your local emergency management office, NOAA/NWS forecasts, local media, and official briefings for updated information and possible watches or warnings.
