000 FZNT25 KNHC 142103 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 403 PM EST Wed Dec 14 2022 ...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...A cold front extending from south-central Louisiana to inland northeastern Mexico will reach from near New Orleans, Louisiana to just south of Tampico, Mexico early this evening, from Apalachicola, FL to the central Bay of Campeche early Thu and from near Sarasota, FL to the central Bay of Campeche Thu night before slowing down and beginning to weaken. A line of strong to severe thunderstorms just out ahead of the front will race eastward across the north-central and NE Gulf tonight through Thu. Strong to near-gale force NW to N winds, with occasional gusts to 35 kt are presently west of the front offshore the Texas coast. These winds will diminish to fresh to strong by early this evening, and to moderate to fresh overnight into Thu for the central and eastern Gulf. Fresh to strong southerly winds ahead of the front will diminish Thu as the front approaches Fl. The front should become stationary Fri night from the Straits of Florida to the south-central Gulf of Mexico before weakening further. The front should remain in about the same position through Sat as a surface trough forms over the SW Gulf. The gradient between this surface trough and high pressure over the southern U.S. is likely to induce a large area of fresh to strong N to NE winds over the central Gulf this weekend. Presently, it appears that the trough will transition to a warm front on Sun and lift northward to the NW Gulf by late Mon. .TONIGHT...SE to S winds 15 to 20 kt. Seas 5 to 7 ft. Isolated showers. .THU...S to SW winds 15 to 20 kt. Seas 5 to 7 ft. Isolated showers. .THU NIGHT...SW winds 10 kt. Seas 4 to 6 ft in S swell. Isolated showers. .FRI...E to SE winds 10 to 15 kt. Seas 3 to 5 ft. Isolated showers. .FRI NIGHT...S of 24N, variable winds less than 5 kt, becoming SE 10 kt late. N of 24N, NE to E winds 10 to 15 kt. Seas 2 to 4 ft. .SAT...SE to S winds 10 to 15 kt. Seas 3 to 5 ft. .SAT NIGHT...S of 24N, S to SW winds 10 kt. Seas 3 ft or less. N of 24N, SW to W winds 10 kt, except behind front shifting to N to NE 15 to 20 kt late, Seas 3 to 5 ft, building to 6 to 8 ft late. .SUN...NE winds 15 to 20 kt. Seas 6 to 8 ft. .SUN NIGHT...NE winds 15 to 20 kt. Seas 6 to 8 ft. .MON...NE to E winds 15 to 20 kt. Seas 6 to 8 ft. .MON NIGHT...E winds 15 kt. Seas 5 to 7 ft. Within 200 nm east of the coast of Florida .SYNOPSIS...A cold front extending from 27N55W to 22N70W will weaken as it shifts eastward through Thu in response to high pressure that builds in behind it. Large long-period N to NE swell will continue to affect much of the area for the next couple of days. A large and powerful low pressure system north of the area will bring strong to near gale force W winds tonight through Thu night to the waters east of 65W and north of 27N. Very large seas can be expected in this area. Farther west, fresh to strong southerly winds will develop offshore NE Florida beginning tonight as a strong cold front approaches the southeastern U.S. coast. The front is forecast to move off the coast Thu afternoon, reach from near 31N74W to West Palm Beach, FL early Fri, and from near 31N65W to the Florida Keys early Sat. Scattered to numerous showers and thunderstorms are likely to move offshore the Florida coast on Thu. On Sun, a reinforcing cold front is expected to merge with it. The merged front is expected to reach from near 31N62W to the central Bahamas and western Cuba Sun night and from near 29N55W to 26N66W and stationary to the central Bahamas by late Mon. The fresh to strong southerly winds will shift eastward across the northern and central waters through Sat and exit the area late Sat. Fresh northwest to north winds will follow in behind the merged front, except becoming moderate to fresh northeast to east winds north of the stationary front. .TONIGHT...SE winds 10 to 15 kt S of 27N, and SE to S 15 to 20 kt N of 27N. Seas 4 to 6 ft. Scattered showers and thunderstorms N of 27N. .THU...SE to S winds 15 to 20 kt S of 27N, and S 20 to 25 kt N of 27N. Seas 4 to 6 ft. Scattered showers and thunderstorms N of 27N.
