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 nearly stationary front extending from south
Florida to south Texas will gradually dissipate through Wed.
Then, a frontal trough will likely persist over the east-
central Gulf through Fri. This system will continue to generate
scattered to numerous showers and isolated thunderstorms, mainly
across the northern half of the basin. Elsewhere, a weak
pressure gradient in place will maintain gentle to moderate
winds with slight to locally moderate seas through Sun. Looking
ahead, winds may increase to fresh speeds across the NW Gulf by
Sun night.
