Synopsis for the Gulf of Mexico
1026 AM EST Wed Nov 13 2019

SYNOPSIS
A cold front extending from the Florida Bay to the
N coast of the Yucatan Peninsula then across the far eastern Bay
of Campeche this morning will shift slightly SE and stall across the
far SE portion of the Gulf this afternoon into tonight, then
begin to drift northward and gradually dissipate Thu. Gale force
winds and high seas will continue across the SW Gulf this
morning before decreasing modestly this afternoon and evening.
Another weaker cold front will move into the Gulf Thu, then moves
SE and clear the basin Fri. Weak low pressure is expected to form
Thu night or early Fri over the northeast Gulf and move slowly NE.
In the wake of this front, gale force winds are likely over
portions of the SW Gulf Fri and Fri night.
