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. Weak high pressure will remain nearby today before a potent cold front crosses the waters late tonight. A strong area of Canadian high pressure builds over the region on late Monday into Tuesday. Another clipper-like system moves through the area by mid-week before a secondary cold front crosses the waters on Thursday. Small Craft Advisories will likely be needed tonight into Monday, and again Tuesday through Wednesday night.
