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.
