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 is likely to form Sunday or Monday before the system moves onshore along the western Gulf of Mexico coast. Regardless of development, this disturbance is expected to produce heavy rains across portions of Central America through Saturday. Meanwhile, a frontal boundary over the northern Gulf will continue through Sun will bring showers and thunderstorms across the region. $$ GMZ011-110230- NW Gulf including Stetson Bank- 1017 AM EDT Fri Sep 10 2021 .TODAY...NE to E winds 10 to 15 kt in the afternoon.
