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 trough from near Pensacola Florida to a 1013 mb
low at 27N88W extends SW to just E of northeastern Mexico. The
trough and low will drift eastward through Monday as a cold
front presently from southeastern Louisiana to just S of
Brownsville Texas quickly moves across the NW and N central
waters. The cold front will reach the far SE Gulf early on
Wednesday and to the NW Caribbean Sea Wednesday night. Winds
behind the front are expected to reach gale force near Veracruz 
Mexico from midday on Monday to Wednesday night. Strong high 
pressure in the wake of the front will bring fresh to strong 
northerly winds over much of forecast waters Wednesday 
afternoon, then diminish through Thursday afternoon as the high 
center shifts to the NE Gulf. The high will weaken on Friday as 
another cold front moves across eastern Texas, and into the NW 
Gulf on Friday night.
