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 builds over New England, while an area of low pressure will likely pass by to the south. This system eventually evolves into a coastal low across the Atlantic Ocean later this evening before tracking out to sea. High pressure briefly builds over the area this weekend while a stronger cold front crosses the waters by late Sunday. A strong area of Canadian high pressure builds over the region on Monday into Tuesday. Small Craft Advisories will likely be needed on Monday, and possibly again on Tuesday.
