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 slowly pull away from the Atlantic coast today. At the same time, a stalled frontal system over the Great Lakes eventually crosses the local waters by Friday morning. High pressure briefly builds over the northeastern U.S. on Saturday before another frontal system looms nearby on Sunday and into early next week. Small Craft Advisories may be needed on Friday behind the cold front. Wind gusts remains elevated over the weekend and into early next week which may prompt additional advisories.
