000 FZNT25 KNHC 291918 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 318 PM EDT Sun Apr 29 2018 ...Please refer to Coastal Waters Forecasts (CWF) available through NOAA Weather Radio and other means for detailed Coastal Waters Forecasts... Southeast Gulf of Mexico .SYNOPSIS...High pressure over the northwest gulf extends a ridge southeastward to the Straits of Florida, while a dry cold front has pushed southward to over the far northern gulf E of 91W. The cold front will dissipate tonight or early Mon as it continues to move south. The high pressure will track northeastward and inland today, then move east off the Georgia coast on Mon with the ridge extending west-southwest across the northern gulf waters through Thu. A weak surface trough will move off the Florida W coast tonight and across the eastern gulf Mon. The trough will be followed by moderate to locally fresh E to SE winds through Tue as it becomes diffuse over the north-central gulf. Fresh to strong NE to E winds will develop over the far southeastern gulf and Straits of Florida beginning Tue, and continue through early Thu as strong high pressure builds southeastward over the western Atlantic. .TONIGHT...NE winds 5 to 10 kt. Seas 2 to 3 ft. .MON...NE to E winds 10 to 15 kt. Seas 3 to 4 ft. Isolated showers. .MON NIGHT...E winds 15 to 20 kt. Seas 3 to 5 ft. Isolated showers. .TUE...E winds 15 to 20 kt, except 20 to 25 kt E of 84W. Seas 4 to 6 ft, except 6 to 8 ft E of 84W. Isolated showers. .TUE NIGHT...E winds 15 to 20 kt, except 20 to 25 kt E of 84W. Seas 3 to 5 ft, except 5 to 8 ft E of 84W. .WED...E winds 15 to 20 kt, except 20 to 25 kt E of 84W. Seas 3 to 5 ft, except 5 to 8 ft E of 84W. .WED NIGHT...E winds 15 to 20 kt, except 20 to 25 kt E of 84W. Seas 4 to 6 ft, except 6 to 8 ft E of 84W. .THU...E winds 15 to 20 kt, except 20 to 25 kt E of 84W early diminishing to 15 to 20 kt. Seas 4 to 6 ft, except 6 to 8 ft E of 84W. .THU NIGHT...E winds 15 to 20 kt, except 20 to 25 kt Straits of Florida. Seas 4 to 6 ft, except 6 to 8 ft Straits of Florida. .FRI...E winds 15 to 20 kt. Seas 4 to 6 ft. .FRI NIGHT...NE to E winds 15 to 20 kt. Seas 3 to 5 ft. Within 200 nm east of the coast of Florida .SYNOPSIS...A weak cold front extends from 31N67W southwest to to 27N73W and becomes a weakening stationary front to central Cuba. The cold front will move slowly southeast and reach from near Bermuda to the central Bahamas tonight and from just east of Bermuda to 27N71W and stationary to west-central Cuba by early Mon afternoon. Scattered show and thunderstorms east of the front will continue to shift eastward tonight. A new cold front from 31N77W to inland Florida near Port Canaveral will quickly move across the rest of the northwest portion through this evening, and across the north-central portion tonight and Mon before it merges with the weak front from near 28N65W to west-central Cuba Mon night. It will then become stationary from near 27N65W to west- central Cuba by early Wed. Strong high pressure will slide eastward near 31N Mon night through early Thu, resulting in a tight pressure gradient N of the front that will bring fresh to strong NE to E winds to much of the central and SW waters. The high should weaken weaken enough on Fri to allow for these winds to diminish. A broad surface trough will approach 65W Thu and 70W Fri. It is expected to be followed by fresh to locally strong E to SE winds, and be accompanied by scattered showers and thunderstorms. .TONIGHT...NE to E winds 10 to 15 kt. Seas 3 to 5 ft.
