Synopsis for the Gulf of America

321 PM EDT Wed Jul 8 2026



.SYNOPSIS...Relatively weak high pressure extending westward

across the basin from the Atlantic will change little through

Thu night, then shift northward to near the northern Gulf coast

Fri through Sat night. The weather pattern will support gentle

to moderate east to southeast winds across the Gulf south of

about 26N, and light to gentle southeast to south winds north of

about 26N. The exception will be occasional fresh to strong 

northeast to east winds offshore the Yucatan peninsula at night. 

A mid to upper- level low along with a moist and unstable airmass 

will generate scattered to numerous showers and thunderstorms over

the SW Gulf, with scattered showers and isolated thunderstorms 

elsewhere across the basin south of about 28N through Thu.
