Synopsis for the Gulf of America

325 PM EDT Sat May 30 2026



.SYNOPSIS...A ridge will continue to dominate the Gulf waters through

midweek supporting gentle to moderate E to SE winds with moderate

seas. The exception will be evening pulses of fresh winds off the

northern Yucatan Peninsula and in the central Gulf through the 

same period. A pronounced deep-layered upper-level trough across 

the western Gulf combined with a very warm, humid and unstable 

airmass will continue to support rounds of showers and thunderstorms,

across the central and eastern Gulf through at least Sun. Frequent

lightning, with gusty winds and locally rough seas are expected 

in strong thunderstorms. Mariners are urged to keep up to date 

with the latest forecasts.
