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...High pressure is building over the northern Gulf,
following a cold front that moved southeast of the basin
overnight. Winds and seas are diminishing across the Gulf as a
result, but fresh to strong N winds and rough seas will persist
through the morning over the eastern Gulf. Afterward, the
pattern will support moderate to locally fresh S to SE winds
over the western and central Gulf, and gentle to moderate winds
in the eastern basin through this weekend. A surface trough will
develop over the Yucatan Peninsula and move into the Bay of
Campeche nightly through Sun, supporting pulses of fresh to
strong winds over adjacent waters. Looking ahead, the next cold
front may enter the northwestern basin early next week.
