Synopsis for the Gulf of America

458 PM EDT Sun Apr 19 2026



.SYNOPSIS...A strong frontal boundary extends southwestward from

near Cedar Key, Florida through a 1018 mb low near 26N96W to 

near Poza Rica, Mexico. Fresh to strong N to NE winds and 

moderate to rough seas will follow the cold front as it moves 

southward across the northern Gulf through Mon. The front is then 

expected to stall from the Florida Straits to southern Texas Mon 

night. On Tue, the western portion of this boundary will gradually

dissipate over the central and western Gulf, while the eastern 

portion will resume moving southward into Cuba and the Yucatan 

Channel. In the wake of the front, gentle to moderate 

southeasterly winds will return to the Gulf on Thu.
