Synopsis for the Gulf of Mexico
1026 AM EST Wed Nov 22 2017

.SYNOPSIS...A 1012 mb low near 26N89W extends a cold front SW to
24N93W and to inland Mexico near 23N98W. The low will slowly
track east-northeastward to the far eastern gulf waters through
early on Friday before moving inland central Florida Friday
afternoon pushing the cold front to the far SE waters by Saturday.
A tight pressure gradient behind the front will bring gale force
conditions to much of the western waters through today, except to
continue over the far SW waters into early on Thursday. High
pressure will build in over the area in the wake of the front
through Sunday allowing for winds and seas to decrease.
