FZNT24 KNHC 232104 OFFNT4 Offshore Waters Forecast for the Gulf of America NWS National Hurricane Center Miami, FL 504 PM EDT Sat May 23 2026 Offshore Waters Forecast for the Gulf of America Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. GMZ001-240800- Synopsis for the Gulf of America 504 PM EDT Sat May 23 2026 .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. $$ GMZ040-240800- NW Gulf of America including Stetson Bank- 504 PM EDT Sat May 23 2026 .TONIGHT...S of 27N, variable winds less than 5 kt, becoming SE to S 10 kt late.
