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 will build from the Midwest to the Mid-Atlantic tonight through Friday night before moving offshore on Saturday. Another cold front and wave of low pressure will approach from the Ohio River Valley on Sunday, then move offshore Monday. Northwesterly wind gusts may briefly approach 20 knots late tonight into early Friday morning over the middle Chesapeake Bay and lower tidal Potomac River. Westerly wind gusts could approach 20 knots Friday afternoon over the upper Chesapeake Bay and upper tidal Potomac River. More widespread gusts around 20 knots are possible out of the south late Friday evening through Saturday afternoon, and again Sunday afternoon and evening. Northerly wind gusts of 20 to 25 knots are possible Monday.
