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...A cold front extends from near Apalachicola, Florida
southwestward to 25N90W and to inland Mexico just N of Veracruz.
Strong to near gale force northerly winds will prevail N of the
front through tonight as it moves SE and gradually stalls across
the Yucatan Channel and Straits of Florida Mon through Mon
night. A brief period of northerly gales is expected offshore of
Tampico and Veracruz this afternoon. Low pressure is expected to
form over the NW Gulf on Mon night, then track southeastward
through Wed, dragging a strong cold front across the entire
basin. Strong high pressure behind the front will induce gale
force north to northeast winds expanding across much of the
northern and western Gulf Tue through Tue night, with the
potential for gusts to storm force across portions of the west
and central Gulf. Mariners are urged to exercise extreme caution
across the basin, due to the expansive area of gale force winds
and a large area of very rough to high seas that is expected to
accompany this next frontal system.
