Synopsis for the Gulf of America

428 AM EDT Thu Jul 9 2026



.SYNOPSIS...High pressure extending westward from the Atlantic 

across central Florida and over the Gulf will change little 

through Sat, then shift slightly southeastward afterward. The 

weather pattern will support gentle to moderate east to southeast

winds south of 26N east of 94W, and light to gentle southeast to 

south-southwest winds north of 26N into the weekend. Light and 

variable winds are south of 26N west of 94W. These winds will 

gentle to moderate east to southeast winds tonight and change

little into next week. The exception will be occasional fresh to 

strong northeast to east winds offshore the Yucatan peninsula at 

night. A mid-level trough within a very moist and unstable 

environment is generating scattered to numerous showers and 

thunderstorms over the SW Gulf. Isolated showers and thunderstorms

are elsewhere south of about 28N. This activity is expected to 

persist into tonight as it lifts north.
