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. An area of low pressure over the Virginia Tidewater will drift offshore through tonight. Hazardous marine conditions are expected through this evening. A cold front will move across the waters Friday night.
