Synopsis for the Gulf of America

1056 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 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.
