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 in place through Friday afternoon before a quick moving clipper system tracks across the waters by Friday night. Another cold front pushes through the region late in the weekend before high pressure approaches from the west early next week. Small Craft Advisories may be needed Saturday, and again Sunday into Monday.
