Synopsis for the Gulf of America

316 PM EDT Wed Apr 29 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 weak

cold front will move into the far northern Gulf Thu and stall

Thu night into Fri. A strong late-season cold front will emerge

off the Texas coast late Fri night. The front will reach from

northern Florida to the Bay of Campeche by late on Sat, then from

central Florida to the Yucatan peninsula on Sun before stalling

over the SE 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. 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.
