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 drop through the region today, then stall to the south as high pressure passes to the north tonight into Monday. The front will return back northward Monday night into Tuesday, followed by another cold front Tuesday night into Wednesday. Small Craft Advisories may be needed for portions of the waters Monday night, and will be likely Tuesday through Wednesday.
