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 slowly build in from the west through Saturday as low pressure gradually moves away from New England. The next low pressure system will approach from the Ohio Valley Sunday before crossing with a series of fronts early next week. Small Craft Advisories may be needed for portions of the waters at times from Saturday afternoon through Monday.
