The forecast indicates potential hazardous conditions for mariners, particularly on Friday and Saturday, when gale-force winds and high waves are expected. Winds could reach up to 35 knots, and wave heights may build to 6 feet in some areas, posing risks to small craft and larger vessels. Showers on Thursday and Friday could further reduce visibility and create challenging navigation conditions. Those operating in the Chesapeake Bay and Tidal Potomac River should exercise caution and prepare for rapidly changing weather conditions.
