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 will remain offshore through tonight. Low pressure will pass north of the area Wednesday, dragging a cold front across the area Wednesday night. High pressure will build south of the area Thursday night into Friday before another frontal system approaches on Saturday. Small Craft Advisories appear likely late Wednesday night through Thursday night, and then possible again on Friday and Saturday. Gale gusts can't be ruled out late Wednesday night into Thursday.
