Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be

Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front extends from a 1011 mb low centered
near 29N84W to the eastern Bay of Campeche near 18N92W. The low
pressure will move into the SW N Atlc and cause the associated
cold front to exit the SE Gulf by Sat morning. Minimal gale
force winds are expected to persist over the SW Gulf this
morning. Winds and seas will begin to gradually diminish across
the gulf on Fri and Sat as the front exits the area and high
pressure builds across the region.
