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 strong cold front will enter the NW Gulf this
afternoon, then reach the southeastern Gulf waters Wed and the
Straits of Florida by Wed evening. In the wake of the front,
strong northerly winds are expected in the western half of the
basin, with gale force winds expected west of 95W on Tue. A
secondary front will drop southward to the northern Gulf early
on Fri and reach the far southwestern Gulf by Fri evening.
Strong high pressure will build in behind this front. The
pressure gradient between the front and a tropical wave that
will approach the western Caribbean is expected to freshen the
northeast winds over most of the southeastern Gulf by the end of
the week.
