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 1014 mb high pressure centered over the SE
Louisiana offshore waters near 27N88W will drift ESE and
dissipate tonight. A cold front extending from Horseshoe Beach,
Florida NW to the coast of Mississippi will exit the NE gulf
this evening, however shower activity associated with it will
linger through Fri. Otherwise, a tropical wave over Guatemala is
forecast to move across southeastern Mexico through tonight
before emerging over the Bay of Campeche on Friday, where an
area of low pressure could form. After that, additional slow
development of this system is possible while it moves NW over
the SW Gulf of Mexico through the weekend. Regardless of
development, moderate to fresh E to SE winds are expected across
the SW and west-central gulf this evening through Sat night.
