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...An area of low pressure over the southwestern Gulf
will meander for the next day or so before moving slowly
northward to northeastward on Fri and Sat, with potential for it
to become a tropical depression or tropical storm within the
next day or so. A Gale Warning is in effect for some sections of
the central and western Gulf with this system. A weak front will
move into the northern Gulf on Fri and reach the eastern Gulf by
the weekend and become stationary. The gradient between the
front and the area of low pressure is expected to lead to fresh
to strong northeast to east winds and building seas over most of
the central and western Gulf into early next week.
