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 surface trough will move into the eastern Gulf Wed
night into Thu morning, bringing fresh E winds. Otherwise, high
pressure pressure will dominate the basin through Fri, producing
mainly gentle to moderate E to SE winds. Fresh winds will pulse
west of the Yucatan Peninsula tonight and again Wed night. A
broad area of low pressure is expected to form Thu over the
southwestern Caribbean. Environmental conditions are forecast to
be conducive for development if the low remains over water, and
a tropical depression could form late this week or this weekend
while the system moves northwestward over the northwestern
Caribbean Sea, across the Yucatan Peninsula of Mexico, and into
the southwestern Gulf of Mexico by Sun. The system has a medium
chance of tropical cyclone formation within the next 5 days.
Regardless of development, confidence is increasing that winds
and waves will increase Sun over the central and SW Gulf of
Mexico.
