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. A stationary frontal boundary will remain off to the south near the Virginia-North Carolina border through tonight. This system returns northward as a warm front Friday which increases thunderstorm chances. High pressure builds across the northeastern U.S on Saturday before another frontal system approaches from the west on Sunday into Monday. Small Craft Advisories may be needed late Sunday due to southerly channeling.
