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. The stalled boundary over the region briefly pulls north today, then returns and stalls nearby tonight through Wednesday. Eventually, this system surges south by Thursday. Small Craft Advisory conditions are possible late Wednesday night through Friday.
