Synopsis for the Gulf of America

456 PM EDT Wed May 27 2026



.SYNOPSIS...A squall line of active thunderstorms continues to

move across the NW Gulf this afternoon, extending from central

Louisiana to NE Mexico. Expect periods of heavy rainfall, 

frequent lightning, wind gusts to gale-force and locally rough 

seas with this activity. Otherwise, the Atlantic ridge extends 

westward across north Florida and the northern Gulf coasts, and 

will sustain moderate to locally fresh SE to S winds through Fri,

then diminish to gentle to moderate over the weekend. The 

exception will be evening pulses of fresh to strong winds off the

northern Yucatan this evening and again Thu. An energetic upper- 

level trough across the west-central Gulf should continue to 

combine with abundant tropical moisture to produce scattered 

showers and strong thunderstorms over the central and eastern Gulf

through Thu. Mariners are urged to keep up to date with the 

latest forecasts.
