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...The tight gradient in place from strong high 
pressure well north of the area is allowing for strong north to 
northeast to east winds over much of the eastern Gulf and 
Straits of Florida. These winds will continue through Fri as a 
north to south aligned surface trough develops over the central 
Gulf. Strong east winds will occur to the east of this trough 
through late Fri night as low pressure begins to develop along 
the trough over or near the north-central Gulf by early on Sat 
and move northeastward to the NE Gulf while deepening during the 
rest of Sat and through Sun evening before it moves inland the 
Florida panhandle Sun. A cold front trailing from this low will 
sweep across the central and eastern Gulf Sat through Sun night 
followed by strong west to northwest winds. These winds will 
diminish early next week as high pressure settles in over the NW 
Gulf.
