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. Canadian high pressure will gradually push toward the Atlantic coast through tonight. A slow-moving cold front across the Great Lakes eventually crosses the waters by Friday morning. High pressure briefly builds over the northeastern U.S. on Saturday before another frontal system looms nearby to finish the weekend. Small Craft Advisories may be needed at times on Thursday due to southerly channeling effects, and on Friday behind the cold front. Winds may again prompt Small Craft Advisories during portions of the weekend.
