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 1015 mb low pres in the central Gulf is producing
a few showers, while the remainder of the basin is dominated by
weak ridging. Looking ahead, a cold front is forecast to reach
the NE Gulf on Fri, then stall, and remain nearly stationary
through Sun with little change in winds and seas. A weak high
pressure regime will persist in the rest of the Gulf through the
weekend into early next week. Under this weather pattern, mainly
gentle to moderate winds and slight to locally moderate seas
will prevail.
