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

Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure from the northern Gulf coast into
South Carolina will shift SW through Sat, allowing a cold front
to move into the NE Gulf tonight, then slowly dissipate as it
moves across the eastern Gulf through Sat. Another cold front
will follow, moving across the eastern Gulf Sun night through
Mon, before stalling southeast of the region by Mon night into
early Tue. Looking ahead, high pressure building in the wake of
the front will support moderate to fresh E winds and building
seas Sun night through mid week.
