Synopsis for the Gulf of America

317 PM EST Sat Dec 20 2025



.SYNOPSIS...Moderate or weaker winds and slight seas will prevail

over much of the Gulf this weekend. Locally fresh E to NE winds 

are expected in the eastern Bay of Campeche and over the Campeche 

Bank each afternoon and night Sun into next week, as a trough 

develops over the Yucatan Peninsula and propagates westward. 

Looking ahead, fresh E winds and moderate seas will develop over 

the central and eastern Gulf on Mon as a cold front moves off the 

coast of the southeastern United States and progresses over the 

northwestern tropical Atlantic. Strong E winds and rough seas may 

develop through the Florida Straits Mon into early Tue.
