Synopsis for the Gulf of America

539 PM EDT Sat May 9 2026



.SYNOPSIS...A weakening stationary front is persisting along the 

coast of the Gulf States, from Florida westward to Texas. A

surface trough is stretching across the far western Gulf. Scattered

showers and strong thunderstorms near these features will linger 

into Sun. These showers and thunderstorms should weaken Sun 

afternoon and evening as the front gradually dissipates. Farther 

south, winds will pulse to strong near the Yucatan Peninsula in 

the evenings through Sun night. Looking ahead, another cold front 

will move into the northern Gulf waters early Mon morning, and 

reach from northern Florida to the Bay of Campeche by late Mon, 

followed by moderate to locally strong N to NE winds. Fresh to 

strong NW winds are expected off Veracruz Mon night into Tue 

morning. Scattered to numerous showers and strong thunderstorms 

are possible ahead of the front. Conditions will improve across 

the Gulf Tue night into Wed as the front weakens.
