GMZ001-191445- Synopsis for the Gulf of Mexico 1042 PM EDT Fri Aug 18 2023 .SYNOPSIS...A surface ridge over the Gulf waters will support mostly gentle to moderate winds and slight seas across the basin through Sat night. Looking ahead, a surface trough is expected to move across the Gulf from east to west Sun through early next week generating fresh to strong winds and moderate seas. A broad area of low pressure could form from this trough. Thereafter, some slow tropical development of this system is possible as it moves westward and approaches the western Gulf of Mexico coastline by the middle of next week. $$ GMZ040-191445- NW Gulf including Stetson Bank- 1042 PM EDT Fri Aug 18 2023 .OVERNIGHT...SE winds 10 kt, shifting to S early in the morning.
