070 FZNT25 KNHC 301342 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 942 AM EDT Wed Sep 30 2026 ...Please refer to Coastal Waters Forecasts (CWF) available through NOAA Weather Radio and other means for detailed Coastal Waters Forecasts... Southeast Gulf of America .SYNOPSIS...Showers and thunderstorms will linger in the SE Gulf through at least this evening. The pressure gradient between high pressure over the eastern United States and lower pressures in Texas and Mexico support moderate to fresh easterly winds over the western Gulf waters. These winds will expand eastward across the basin by tonight as the pressure gradient tightens. The gradient will weaken from west to east by the end of the week into the weekend as a frontal boundary approaches the western Gulf waters, possibly moving into the basin by the end of the weekend with weakening winds and subsiding seas ahead of it. Increasing winds and building seas are possible behind the very slow moving front. .THIS AFTERNOON...SE winds 10 to 15 kt. Seas 2 ft or less, building to 3 ft in the afternoon. Scattered showers and isolated tstms. .TONIGHT...E to SE winds 15 to 20 kt. Seas 3 to 5 ft. Scattered showers and isolated tstms. .THU...E to SE winds 15 to 20 kt. Seas 3 to 5 ft.

Within 200 nm east of the coast of Florida .SYNOPSIS...High pressure will persist across the region over the remainder of the week and into the weekend supporting moderate to locally fresh easterly winds south of 25N. Moderate or weaker winds will prevail elsewhere. Meanwhile, the remnants of Post-Tropical Cyclone Fay currently east of the offshore waters may move west of 55W by tonight.
