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 frontal boundary stalls just to our south today, with mostly dry conditions. Daily shower and thunderstorm chances return to the forecast Wednesday, with gusty winds possible in the strongest thunderstorms especially later this week. Additional Small Craft Advisories may be needed at times late this week due to periods of southerly channeling.
