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...A cold front sweeping across the basin extends from
SW Florida to the Yucatan Channel tonight. Active thunderstorms
along and ahead of the front will shift SE and exit the basin
with the front late tonight. Minimal gale force winds will
prevail offshore Veracruz through near sunrise. Fresh to strong
N winds and building seas are expected elsewhere behind the
front. High pressure will build in the wake of the front with
marine conditions gradually improving from W to E through the
end of the week. The high pressure will become centered over the
NE Gulf early Sun when gentle to moderate SE to S winds are
expected over the eastern Gulf, with moderate to locally fresh
SE to S return flow over the western Gulf.
