Synopsis for the Gulf of America

339 PM EDT Fri Apr 18 2025



.SYNOPSIS...Fresh to strong NE winds will pulse offshore of the

Yucatan Peninsula and in the eastern Bay of Campeche through

this weekend as a trough develops daily and moves westward.

Elsewhere, fresh to locally strong SE winds will spread across

much of the basin as the pressure gradient increases between low

pressure over the Southern Plains and high pressure E of

Florida. Seas will also build through the weekend. Conditions

will gradually improve next week as the pressure gradient

relaxes.
