Marine Weather HF Voice Broadcast for the Gulf of America

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 weak stationary frontal boundary extends from
southeastern Louisiana to inland Texas near Corpus Christi. It
will lift northeastward as a warm front later today as low
pressure develops near the Texas and Oklahoma panhandles. The
eastern portion of this boundary is a cold front that is
approaching the western Florida panhandle. It will move across
the NE Gulf today into this evening. Expect fresh southerly flow
off the Texas coast tonight through Mon night supported by the
gradient between low pressure over northeast Mexico and high
pressure that will be centered just offshore the Mid-Atlantic
coast. These winds will diminish Tue ahead of a frontal boundary
that will be nearing the Texas coast. A stronger reinforcing
cold front will overtake the frontal boundary early Wed while
emerging out over the NW Gulf. The cold front will then sweep to
the southeast of the basin by late Thu, followed by fresh
northeast winds and building seas. Scattered showers and
thunderstorms may accompany the initial frontal boundary.
