523 FZNT25 KNHC 130845 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 445 AM EDT Sun Jul 13 2025 ...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...Weak high pressure prevails across the NE Gulf this morning, producing gentle to moderate E to SE winds across much of the rest of the basin. The high will drift slowly westward and into the NW Gulf by Wed. This will allow a broad area of low pressure expected to form across the Atlantic east of Florida, to shift westward across Florida and into the eastern Gulf on Tue, then continue to drift westward into the central Gulf through Thu, accompanied by active weather. Environmental conditions could become marginally conducive for the gradual development of this system by mid to late next week. .TODAY...NE to E winds 5 to 10 kt. Seas 2 ft or less. .TONIGHT...N to NE winds 5 to 10 kt. Seas 2 ft or less. .MON...NW to N winds 5 to 10 kt. Seas 2 ft or less. Scattered showers and isolated tstms. .MON NIGHT...N winds 5 to 10 kt. Seas 2 ft or less. Scattered showers and isolated tstms. .TUE...NW to N winds 5 to 10 kt. Seas 2 ft or less. .TUE NIGHT...SW to W winds 5 to 10 kt, shifting to SE to S after midnight.

Seas 3 ft. .THU NIGHT...E to SE winds 10 to 15 kt. Seas 3 to 5 ft. Within 200 nm east of the coast of Florida .SYNOPSIS...1020 mb Atlantic high pressure near 29N69W will shift NE and collapse today, leaving a weak Atlantic ridge along 30N and east of 75W through Mon. High pressure will then build westward across the region and into Florida Tue through Thu. A broad area of low pressure is expected to form over the next few days offshore of the southeastern U.S. coast, and build into the waters north of the Bahamas. This system is expected to move generally westward across the Florida Peninsula Mon and over the eastern and north-central portion of the Gulf of America Tue through Wed. Active weather is expected over the waters west of 75W today through Tue associated with this system. The pressure gradient between the Atlantic ridge building westward and the area of low pressure will support moderate to fresh SE to S winds across the Bahamas and through the NW zones Tue through early Thu. .TODAY...S of 27N, SE winds 5 to 10 kt, shifting to NE in the afternoon. N of 27N, SW to W winds 5 to 10 kt. Seas 2 ft or less. Scattered showers and isolated tstms. .TONIGHT...SE winds 5 to 10 kt, shifting to S to SW after midnight. Seas 2 ft or less.
