GMZ001-200915- Synopsis for the Gulf of Mexico 507 PM EDT Sat Aug 19 2023 .SYNOPSIS...A surface ridge over the Gulf waters will support mostly gentle to moderate winds and slight seas across the basin through tonight. Looking ahead, an area of disturbed weather located near the northwestern and central Bahamas is expected to move into the Gulf of Mexico by early next week, where a broad area of low pressure is expected to form. Some slow development of this system is possible thereafter, and a tropical depression could form as it moves westward and approaches the western Gulf of Mexico coastline by the middle of next week. This system has a low chance of development in 48 hours and a medium chance in the next 7 days. $$ GMZ040-200915- NW Gulf including Stetson Bank- 507 PM EDT Sat Aug 19 2023 .TONIGHT...SE winds 10 kt.
