Synopsis for the Gulf of America

421 AM EST Thu Feb 19 2026



.SYNOPSIS...Moderate to occasionally fresh S to SE winds and

moderate seas are expected over the central and western Gulf

through Fri as ridging prevails over the eastern basin. Locally

strong E to SE winds will pulse in the south-central basin,

north of the Yucatan Peninsula, each afternoon and night through

Fri as a trough develops daily over the region. Looking ahead, a

strong cold front is slated to move into the northern Gulf this

weekend and sweep over the basin through early next week. Gale

force winds and very rough seas will be possible offshore of

Tampico and Veracruz Sun into Mon, and widespread fresh to

strong N to NE winds and rough seas are expected elsewhere in

the wake of the front.
