Marine Weather HF Voice Broadcast for the Gulf of Mexico

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...A stationary front extends from Sarasota, Florida,
SW to the Bay of Campeche, connecting to a 1010 mb low pressure.
There is also a low pressure trough over the Yucatan Peninsula.
The stationary front will transition into a cold front as a
secondary cold front moves through the northern Gulf. Fresh to
strong winds are expected offshore Texas behind this secondary
front. The low is forecast to lose its identity along the front
later this morning. Scattered showers and thunderstorms will be
focused along and near the front today. Some of this activity
may produce strong gusty winds and rough seas. High pressure in
its wake will shift eastward through Sat night as a cold front
reaches eastern Texas. Fresh to strong southerly return flow
will develop over the NW Gulf Fri, shift to the central Gulf
early Sat and diminish by late Sat as the cold front moves
across the NW Gulf and central Gulf waters.
