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. Canadian high pressure will build over the region through this evening, then move off the New England coast by tonight. Multiple weak areas of low pressure may track south of the area through Tuesday afternoon. A frontal system to the south returns northward as a warm front late Tuesday into Wednesday. This boundary remains just north of the waters through much of the week.
