Individual waves may be more than twice the significant wave height. GMZ001-101400- Synopsis for the Gulf of America 956 PM EDT Mon Mar 9 2026 .SYNOPSIS...A broad surface ridge extending across the basin will prevail through midweek. 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 evenings, and slightly weaker winds overall in the northeastern Gulf. Seas will be slight to moderate through Wed. A cold front will impact the northwestern Gulf beginning Wed night, before moving across the basin through Fri night. In the wake of the front, winds will increase to fresh to strong speeds and seas will build to 7 to 10 ft through Thu night with conditions improving thereafter. $$ GMZ040-101400- NW Gulf of America including Stetson Bank- 956 PM EDT Mon Mar 9 2026 .OVERNIGHT...SE winds 15 kt.
