GMZ001-102115- Synopsis for the Gulf of Mexico 515 AM EDT Fri Sep 10 2021 .SYNOPSIS...The northern portion of a tropical wave is producing disorganized showers and thunderstorms over the NW Caribbean. This system is forecast to move into the Bay of Campeche and merge with a pre- existing surface trough located over the southwestern Gulf of Mexico by this weekend. Environmental conditions are expected to be conducive to support gradual development, and a tropical depression could form Sunday or Monday before the system moves onshore along the western Gulf of Mexico coast. This system has a low chance of development in 48 hours and medium chance in the next 5 days. Regardless of development, this system could bring an increase in winds and seas across the Gulf waters during the upcoming weekend. Meanwhile, a frontal boundary over the northern Gulf will continue through Sun will bring showers and thunderstorms across the region. $$ GMZ011-102115- NW Gulf including Stetson Bank- 515 AM EDT Fri Sep 10 2021 .TODAY...NE to E winds 10 to 15 kt.
