Synopsis for the Gulf of America
1116 AM EDT Sun Oct 18 2026
.SYNOPSIS...A cold front extends across the Straits of Florida and

Veracruz. Fresh to strong NE winds, with higher gusts, will continue
over the NE Gulf through Mon. The front will slow down over the

Fresh to strong NE winds and rough seas will persist elsewhere north
