Individual waves may be more than twice the significant wave height. GMZ001-091915- Synopsis for the Gulf of America 303 AM EDT Mon Mar 9 2026 .SYNOPSIS...An old frontal boundary near the coast of Texas and Louisiana will continue to trigger showers and thunderstorms in the NW Gulf early today. Otherwise, a broad surface ridge extending across the basin will prevail through midweek. The pressure gradient between the ridge and low pressure over Mexico will support mainly moderate to fresh E to SE winds basin-wide, pusling to between 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 may impact the northwestern Gulf beginning Wed night, before moving across the basin through Fri night with increasing winds and seas behind it. $$ GMZ040-091915- NW Gulf of America including Stetson Bank- 303 AM EDT Mon Mar 9 2026 .TODAY...SE to S winds 10 kt.
