Synopsis for the Gulf of America

357 PM EDT Fri Mar 27 2026



.SYNOPSIS...Weak high pressure will persist over the northern

Gulf through tonight. 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 the

middle of the next week. The next cold front will move into the 

northern Gulf by Sat morning, reach from south Florida to near SE

Louisiana by Sun morning, and move southeast of the basin late on

Sun. Fresh to strong NE to E winds and moderate seas are expected

in the wake of the front over the northern Gulf on Sat morning.

Then, similar wind speeds are forecast over the eastern Gulf late

Sat through Sun. The pressure gradient will remain strong enough 

to sustain fresh east winds and moderate to rough seas across the 

southeast Gulf and the Straits of Florida through the middle of 

the next week.
