Synopsis for the Gulf of America
1031 PM EDT Wed Sep 3 2025
.SYNOPSIS...A frontal trough extends from the Florida Keys to the
west-central Gulf and this boundary is likely to persist over the
east-central Gulf through Sat. This system will continue to
generate scattered to numerous showers and isolated thunderstorms,
mainly across the eastern part of the basin. A cold front is
forecast to enter the northern Gulf waters on Sun, becoming
stationary early next week. A slight increase in winds and seas is
expected behind the boundary. Elsewhere, a weak pressure gradient in
place will maintain gentle to moderate winds with slight to locally
moderate seas through the forecast period.
