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. A warm front will lift across the Mid-Atlantic tonight, followed by a cold front crossing from west to east Wednesday morning. A second stronger cold front will follow Wednesday afternoon and evening. Low pressure will linger over southeastern Canada while high pressure builds across the Midwest and Tennessee Valley through Friday. High pressure will move overhead Saturday, then move offshore Sunday into early next week as the next systems approach from the west. Small Craft Advisories will likely be needed through Friday night, with gales possible Friday.
