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. High pressure exits off the Atlantic coast before the next frontal system slowly approaches from the west. The associated cold front crosses the waters by late Wednesday before a trough of low pressure lingers through the remainder of the week. Small Craft Advisories are likely needed by Wednesday afternoon due to increasing southeasterly winds. Hazardous marine conditions likely persist through the late week timeframe.
