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. High pressure briefly will build over the northeastern U.S. on Saturday before a frontal system looms nearby on Sunday and into early next week. Wind gusts remain elevated at times Saturday night through Wednesday, which may prompt Small Craft Advisories.
