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...Weak high pressure across the NE Gulf will slide

eastward and into the Atlantic through Sat to produce moderate

to occasionally fresh E to SE winds across the S and W Gulf.

Otherwise, moderate or weaker winds and slight seas are expected

over the remainder of the basin through Sat. The next cold front

is expected to enter the northern Gulf on Sun morning, bringing

increasing winds and building seas behind the front. The front

is expected to reach the southern Gulf along 24N by Mon morning

and move south of the basin late Mon night.
