Coastal Waters Forecast

National Weather Service Baltimore MD/Washington DC

FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY.

Tidal Potomac River and Maryland portion of Chesapeake Bay. Forecasts of wave heights do not include effects of wind direction relative to tidal currents. Expect higher waves when winds are blowing against the tidal flow. Waves flat where waters are iced over. A stationary front near the Virginia-North Carolina border will return northward as a warm front this evening before another cold front crosses the region by Monday morning. High pressure returns for early next week. Small Craft Advisories will likely be needed Monday in the wake of the cold front.
