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 cold front extending from the Big Bend of Florida 

through the Yucatan Channel will drift eastward today before 

exiting the basin on Tue. Scattered thunderstorms are expected 

along and east of the front today, and gusty and erratic winds 

and rapidly building seas will be possible near convection. 

Elsewhere, pulsing moderate to fresh W winds are expected across 

the northern Gulf through early Tue as a trough moves eastward 

over the region. Otherwise, high pressure will build over the 

basin this week. A strengthening pressure gradient between 

deepening low pressure in the central United States and the 

aforementioned high will support fresh to locally strong S to SE 

winds and rough seas offshore of Texas and Mexico Tue through 

late week.
