Synopsis for the Gulf of Mexico

.SYNOPSIS...A 1023 mb high pressure east of northern Florida is
sustaining fresh to locally strong southerly flow across the
entire Gulf through tonight. A strong cold front is forecast to
enter the northwestern Gulf Fri morning, causing strong to near-
gale northerly winds and building seas. As this front moves
southeastward, these conditions will spread to the north-central
and southwestern Gulf by Fri afternoon. Winds will reach
near-gale to gale force at the west-central Gulf and western Bay
of Campeche near Veracruz, Mexico Fri afternoon through evening.
This front will reach from southern Florida to the eastern Bay
of Campeche on Sat evening, bringing strong to near-gale N to NE
winds into the northeastern and central Gulf. Frequent gusts to
gale-force are possible at the central Gulf Sat evening through
Sun. As the front continues southeastward passing the Yucatan
Channel and Florida Straits on Sun night, both winds and seas
should gradually subside across the Gulf on Mon.
