Synopsis for the Gulf of America
946 AM EST Tue Dec 30 2025

.SYNOPSIS...Gale force N to NW winds and very rough seas peaking 
near 21 ft will prevail in the western Bay of Campeche through 
late tonight, in the wake of a cold front sweeping over the 
southern Gulf of America. Fresh to strong N winds and rough seas 
occurring over much of the basin behind the front will slowly 
diminish from north to south this afternoon through Wed morning. 
High pressure is expected to build over the basin on Wed, 
supporting moderate or weaker winds and slight seas region-wide 
through Thu. Looking ahead, fresh W to SW winds may develop over 
the northern Gulf by late week, ahead of a low pressure system 
moving across the southern United States.
