Synopsis for the Gulf of America
1121 AM EDT Sun Apr 19 2026

.SYNOPSIS...A strong frontal boundary extends southwestward from
near Apalachicola, Florida through a 1017 mb low near 26N96W to
south of Tampico, 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.
