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 briefly build overhead through the day, then depart tomorrow as low pressure develops over the middle of the country. This area of low pressure will likely pass south of the waters Sunday into Monday before high pressure briefly returns through midweek. Small Craft Advisories may need to be extended into Thursday night for portions of the waters, and may be needed again late Sunday into Monday.
