Marine Weather HF Voice Broadcast for the Gulf of America

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...A cold front entering the northwestern Gulf today
will move southeastward over the basin through Fri, and fresh to
locally strong N to NE winds and moderate seas will occur in the
western Gulf behind the front into Fri afternoon. Localized near-
gale force winds will be possible offshore of northeastern
Mexico early on Fri. Mainly moderate or weaker winds are then
expected over the basin Fri evening into Sun. Looking ahead, a
new cold front is expected to enter the northwestern Gulf late on
Sun and sweep over the basin into early next week, leading to
fresh to strong N to NW winds and building seas in the wake of
the front.
