FZNT25 KNHC 232105 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 505 PM EDT Sat May 23 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...High pressure extending from the western Atlantic to the northern Gulf will change little through late Mon, then weaken for the remainder of the week. The related pressure gradient will maintain a gentle to moderate east to southeast wind flow through early Sun, except for light to gentle southeast winds W of about 94W tonight through Tue as a weak trough develops off the Texas coast. Winds then generally become southeast at gentle to moderate speeds across the basin through midweek, with slight to moderate seas, with the exception of fresh to strong winds pulsing off NW Yucatan from the late afternoons and into the night time hours due to local effects associated with a thermal trough. Scattered to numerous showers and thunderstorms over the NW and northern Gulf W of 89W are capable of producing frequent lightning, gusty winds and heavy rainfall reducing visibility. This activity will continue into tonight. Additional activity is likely to develop again late tonight into early Sun. In addition, increasing moisture over the southeastern Gulf beginning around the middle portion of the upcoming week should lead to increasing chances for unsettled weather in that part of the Gulf. Mariners are urged to keep up with the latest forecast. .TONIGHT...E to SE winds 10 to 15 kt. Seas 3 to 4 ft. Isolated showers and thunderstorms. .SUN...E to SE winds 10 to 15 kt. Seas 3 to 4 ft.

Within 200 nm east of the coast of Florida .SYNOPSIS...High pressure will continue to dominate most of the forecast region into early next week. Fresh to strong trades will pulse north of Hispaniola during the afternoons and evenings going into early next week. The western part of a backdoor cold front will push south across the eastern portion of the area from Sun evening into Mon before stalling near 27N, then begin to weaken, dissipating on Tue. Fresh to strong northeast winds along with moderate to rough seas will follow the front, subsiding late Tue. Elsewhere, trades are forecast to increase over most of the western half of the area starting Mon, including the waters between Cuba and the Bahamas as well as the entrance to the Windward Passage as initially stronger Atlantic high pressure begins to shift east-southeastward tightening the pressure gradient. The high pressure will then begin to weaken Wed allowing for the tight gradient to slacken leading to diminishing trades. .TONIGHT...E to SE winds 15 to 20 kt.
