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 low pressure system will approach from the Ohio Valley this evening, with a frontal boundary stalling near the region through the middle part of the week. Daily shower and thunderstorm chances return to the forecast, with gusty winds possible in the strongest thunderstorms especially later this week. Small Craft Advisories may need to be extended through Monday morning due to southerly channeling. Additional advisories may be needed at times due to periods of southerly channeling.
