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 extends across the basin from
30N86W to 21N97W. The front will continue moving SE across the
basin. 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 this morning. A secondary frontal
boundary 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 broad low pressure that is expected to
form over the western Caribbean by the end of the week is
expected to freshen the northeast winds over most of the
southeastern Gulf by the end of the week. These winds may reach
strong speeds on Sat along with building seas.
