Synopsis for the Gulf of America

323 PM EDT Thu Apr 30 2026



.SYNOPSIS...A weak pressure gradient will 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 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 early on Sat, 

and on Sat night near Veracruz. Seas are forecast to build to 

around 14 ft in the area of strongest winds through the weekend. 

Mariners are advised to keep up with the latest forecasts.
