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. High pressure over New England this morning will drop southward to the Mid-Atlantic coast through Tuesday, then drift offshore during the second half of the week. A warm front will approach from the Ohio Valley and southern Appalachians Tuesday night, then lift across the area Wednesday. A surface trough likely lingers near the waters Thursday into Friday before a cold front crosses. Small Craft Advisories will likely be needed for portions of the waters in southerly flow Tuesday afternoon through Wednesday night.
