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 cold front will approach from Pennsylvania today, then drop into the Mid-Atlantic and stall Thursday roughly southwest of the Potomac River. The front will lift back northward as a warm front Friday into Saturday, then will be followed by a cold front Saturday night. Small Craft Advisories may be needed for portions of the waters in east to southeast flow Friday night into Saturday.
