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...Moderate to occasionally fresh S to SE winds are 

expected over much of the Gulf today ahead of a cold front moving

through the southern United States. The front is slated to enter

the northwestern basin later today, and fresh to locally strong 

N to NE winds and moderate seas will occur in the western Gulf 

behind the front into Fri afternoon, with localized near-gale 

force winds possible offshore of northeastern Mexico. Mainly 

moderate or weaker winds are then expected over the basin Fri 

night into Sun. Looking ahead, a new cold front is expected to 

enter the northwestern Gulf on Sun and sweep over the basin into 

early next week, leading to fresh to strong N to NW winds and 

building seas in the wake of the front.
