National Weather Service Baltimore MD/Washington DC

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.

Small Craft Advisories may be needed for portions of the waters Monday.
