Synopsis for the Gulf of America

437 AM EDT Thu Apr 30 2026



.SYNOPSIS...A weak pressure gradient will generally maintain

gentle to moderate southeast to south winds across the basin,

except for light to gentle variable winds over the NE Gulf

through Fri. Moderate seas will be over the western Gulf while

mostly slight seas will be elsewhere through Fri. A diurnal

trough will pulse fresh to strong winds off the Yucatan

Peninsula during the evenings and at night through Fri. A strong

late-season cold front will emerge off the Texas coast Fri

night. The front will reach from northern Florida to the Bay of

Campeche by late Sat, then from central Florida to the Yucatan

peninsula on Sun before stalling over the southeastern Gulf Mon.

The front will be followed by fresh to strong north to northeast

winds, with winds reaching gale-force offshore Tampico and

Veracruz on Sat, lasting to into Sat night offshore Veracruz.

Seas are forecast to build to around 12 ft, but possibly higher

over waters affected by the gale conditions before subsiding Sun

and Sun night. Scattered showers and thunderstorms, some

possibly strong, are expected to precede the front. Mariners are 

advised to keep up with the latest forecasts.
