FZNT24 KNHC 110749 OFFNT4 Offshore Waters Forecast for the Gulf of America NWS National Hurricane Center Miami, FL 349 AM EDT Wed Mar 11 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. GMZ001-112000- Synopsis for the Gulf of America 349 AM EDT Wed Mar 11 2026 .SYNOPSIS...A broad surface ridge extending across the basin will prevail through today. The pressure gradient between the ridge and lower pressures over Mexico will support mainly moderate to fresh E to SE winds basin-wide, pulsing to fresh and strong near the northern Yucatan and the western Gulf in the early morning and evening, with slightly weaker winds overall in the northeastern Gulf. Seas will be slight to moderate today. A cold front will impact the NW Gulf beginning tonight, before moving across the basin through Thu night, stalling and dissipating over the SE Gulf Fri and Fri night. In the wake of the front, winds will increase to fresh to near gale-force speeds, and seas will build to 8 to 11 ft through Thu night, with conditions improving thereafter as ridging gradually rebuilds across the basin. Another cold front may approach early next week. $$ GMZ040-112000- NW Gulf of America including Stetson Bank- 349 AM EDT Wed Mar 11 2026 .TODAY...S winds 15 kt.
