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...Strong thunderstorms are expected to continue across
W Gulf of Mexico through Fri and will be capable of producing
locally near-gale force winds and seas to 10 ft. Meanwhile, a
strong ridge stretching from eastern seaboard to the NE Gulf
will continue to dominate the Gulf waters through the remainder
of the week. The pressure gradient between the ridge and
deepening low pressure across the Southern Plains and northern
Mexico will result in fresh to strong SE winds and high seas
across the Gulf region through Sat. Seas will peak 10 to 13 ft
today through Fri in the Straits of Florida and 12 ft in the N
central Gulf on Fri.
