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...Strong thunderstorms moving eastward across the 
northeastern Gulf of America will continue through this evening, 
producing strong winds and rough seas in the region. A surface 
trough over the Yucatan Peninsula is expected to move westward 
through the Bay of Campeche tonight, promoting locally fresh SE 
to NE winds over the region into early Tue. A similar pattern is 
expected Tue night, with to fresh to locally strong winds in this
area. Elsewhere, fresh to strong SE to S winds will develop Tue 
night across much of the basin west of 85W, as the pressure 
gradient tightens between building high pressure in the western 
Atlantic and strengthening low pressure in the south-central 
United States. Building rough seas of 8 to 11 ft are expected in 
this region Wed morning through late week. East of 85W, moderate 
SE winds Tue night will strengthen to fresh to locally strong 
speeds Wed into Thu, including through the Florida Straits.
