Synopsis for the Gulf of America

1105 AM EDT Thu May 28 2026



.SYNOPSIS....The Atlantic ridge extends across Florida into the

Gulf region. This system will sustain moderate to locally fresh 

SE to S winds through Fri, then diminish to between gentle and 

moderate over the weekend. The exception will be evening pulses of

fresh winds off the northern Yucatan through this weekend. A 

pronounced upper-level trough across the western Gulf should 

continue to combine with abundant tropical moisture to produce 

scattered heavy showers and strong thunderstorms over the west and

central Gulf until this evening, then over the eastern Gulf 

tonight and Fri. 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.
