Synopsis for the Gulf of Mexico
332 PM EST Thu Nov 23 2017

SYNOPSIS
A cold front extends from a 1009 mb low centered near
29N83W to the Yucatan Peninsula near 21N89W. The low will move
into the SW N Atlc and cause the associated cold front to exit the
SE Gulf Fri night. Fresh to strong winds and NW swell behind the
front will begin to gradually diminish and subside across the
gulf on Fri and Sat as the front exits the area, and as high
pressure builds across the region. The next cold front may move
into the NW Gulf Tue night.
