more than twice the significant wave height.

Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure extending across the basin from the
western Atlantic will begin to shift eastward tonight as a
rather weak cold front approaches the NW Gulf coast. Winds will
generally remain at gentle to moderate speeds throughout tonight
into early Sun. Winds will pulse fresh to strong this evening
near the northern Yucatan Peninsula. The cold front is forecast
to move into the NW Gulf late tonight into early Sun, then reach
the southeastern Gulf Mon evening as it weakens. Fresh to
locally strong winds and building seas will follow the front
through Sun night, with fresh to strong winds persisting near
Veracruz through Mon evening. High pressure will again settle
over the region by Tue and change little through Thu night. The
pressure gradient between the high pressure and lower pressure
over the southern Plains is expected to increase SE winds in the
western Gulf starting on Thu.
