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. Behind an earlier cold front, high pressure builds in from the Tennessee Valley through Tuesday. As this system departs, a warm front tracks across the waters early Wednesday before a potent cold front pushes through the region on Thursday into Friday morning. Small Craft Advisories may be needed late tonight for northerly channel, and again on Wednesday into Thursday with the next low pressure system and cold front.
