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 cold front extends from Fort Myers Florida to
27N94W where it becomes a warm front to a weak 1016 mb low over
the NW Gulf near 26N96W. A stationary front then trails from the
low to 24N96W to 21N97W. A tight gradient between the fronts and
strong high pressure over the central United States that is
building east-southeastward over the southeastern United States
is allowing for strong NE winds over the northern half of the
basin W of 89W, and fresh N to NE winds E of 89W. The cold front
will continue to move quickly across the Gulf E of 96W through
tonight and become stationary over the SE Gulf on Mon. The low
will slowly move northeastward through Mon night, then east
northeastward across the N central waters through Thu night and
the NE Gulf by Fri, dragging a new cold front across the SW
Gulf. The tight gradient will gradually slackens allowing for
the fresh to strong winds to slightly diminish Mon through early
Tue. These winds are expected to increase again again late Tue
or Wed as another low pressure forms over the NW Gulf and tracks
northeastward toward northern Florida.
