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...Weak high pressure centered in SE Gulf will
dissipate this evening. A cold front extending from the Florida
Big Bend to southern Louisiana will stall early this evening,
however showers and tstms associated with it will linger across
the NE gulf offshore waters through early Fri. Otherwise, a
tropical wave over northern Guatemala and southeastern Mexico is
forecast to emerge 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. By Saturday night, the system is expected
to move inland over northeastern Mexico. Regardless of
development, moderate to fresh E to SE winds are expected across
the SW and west-central gulf this evening through Sun.
