Synopsis for the Gulf of America
323 PM EDT Mon Sep 21 2026
.SYNOPSIS...A very weak pressure gradient will force only gentle

level low will promote scattered showers and thunderstorms over
the SE Gulf and the Straits of Florida for at least the next two
days. Looking ahead, a cold front should dip into the NE Gulf
Thu night and Fri, but accompanied with little to no increase in
the winds.
