Individual waves may be more than twice the significant wave height. GMZ001-101515- Synopsis for the Gulf of Mexico 1108 PM EDT Thu Sep 9 2021 .SYNOPSIS...The northern portion of a tropical wave is producing disorganized showers and thunderstorms across the western Caribbean Sea. 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 some gradual development, and a tropical depression could form by early next week before the system moves inland over mainland Mexico. 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. $$ GMZ011-101515- NW Gulf including Stetson Bank- 1108 PM EDT Thu Sep 9 2021 .OVERNIGHT...E winds 10 to 15 kt.
