Synopsis for the Gulf of America

917 AM 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, and from central Florida to the 

Yucatan peninsula on Sun. 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.
