Synopsis for the Gulf of America

520 AM EDT Fri Mar 27 2026



.SYNOPSIS...High pressure of 1020 mb over the NE Gulf will move NW

and inland Louisiana this afternoon. A trough over the Bay of 

Campeche will support moderate to fresh winds off the northern and

western coasts of the Yucatan Peninsula, mainly at night, through

Tue night. The next cold front will move into the northern Gulf 

early Sat morning, reach the southeast Gulf by Sun morning, and 

move southeast of the basin late on Sun. Fresh to strong NE to E 

winds and rough seas are expected in the wake of the front over 

the eastern Gulf Sat night through early Mon. The pressure 

gradient will remain strong enough to sustain fresh to strong east

winds across the southeast Gulf and the Straits of Florida 

through the middle of the next week.
