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...Fresh to strong northerly winds will continue to
affect the eastern Gulf through early Tue morning as high
pressure continues to build in the wake of a cold front that
moved out of the basin during the morning hours. Fresh to strong
SE wind will develop over the western half of the Gulf tonight
into Tue ahead of the next cold front forecast to come off the
coast of Texas Wed morning. The front will reach from southern
Alabama to Veracruz Wed night, from Cape Coral to the Yucatan
Peninsula Thu afternoon, and exit the basin Thu night into Fri.
The front will be followed by fresh to strong winds and rough
seas that will start to diminish Fri morning.
