Marine Weather HF Voice Broadcast for the Gulf of Mexico

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 for the Gulf of Mexico

.SYNOPSIS...A surface ridge over the Gulf waters will support
mostly gentle to moderate winds and slight seas across most of
the basin today. Moderate to fresh winds are noted in the
eastern Gulf due to a trough extending across the region.
Looking ahead, an area of disturbed weather located in the far
eastern Gulf of Mexico is expected to lead to the formation of a
broad area of low pressure early this week. Some slow
development of this system could occur thereafter as it moves
westward at about 15 to 20 kt, and a tropical depression could
form as it approaches the western Gulf of Mexico coastline by
Tuesday. This system has a low chance of development in 48 hours
and a medium chance in 7 days.
