Synopsis for the Gulf of America

945 AM EDT Thu Apr 30 2026



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

moderate to fresh southeast winds across the western half of the basin,

and light to gentle variable winds over the eastern half through 

Fri. Moderate seas will be over the western Gulf, while slight 

seas will be elsewhere through Fri. A diurnal trough will pulse 

fresh to strong winds off the Yucatan Peninsula during the 

nighttime hours 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, and on Sat night

near Veracruz. Seas are forecast to build to around 13 ft in the

area of strongest winds through the weekend. Mariners are advised

to keep up with the latest forecasts.
