FZNT24 KWNM 250915 OFFN02 NAVTEX Marine Forecast for Mid-Atlantic states waters NWS Ocean Prediction Center Washington DC 515 AM EDT Fri Sep 25 2026 Conditions given represent the highest within that period. Locally higher winds and seas can be expected in and near tstms. ...Please refer to Coastal Waters Forecasts (CWF) available through NOAA Weather Radio and other means for detailed coastal waters forecasts... .SYNOPSIS...Intensifying low pressure centered about 200 nm E of Cape Hatteras early this morning will track slowly to the N and NW today into Sat night while approaching western Long Island or New Jersey Sat night, slow and turn to the SW and S while weakening Sun, and then gradually turn more towards the E Sun night while passing over the far N waters. The weakening low is forecast to pass NE of the waters Mon through Tue night and high pressure builds towards the northern Mid-Atlantic coast. Strong counterflow to the Gulf Stream will create large, very steep, and possibly breaking waves resulting in a particularly hazardous sea state. A secondary cold front will move offshore late Sun into Sun night, stall across the area Mon into Tue, then dissipate late Tue into Tue night. Mariners should continue monitoring forecasts as the intensifying low pressure system slowly crosses the region into the weekend, and consider avoidance plans as needed. This will be a long duration event, and highly impactful to the mariner. Sandy Hook to 37.5N ...STORM WARNING... .TODAY...N winds 40 to 55 kt. Seas 14 to 28 ft. Rain likely.
