Synopsis for the Gulf of Mexico
425 PM EDT Mon Oct 23 2017

.SYNOPSIS...A cold front extends from Apalachee Bay to 24N90W to
inland Mexico near Veracruz. The front will reach from Tampa to
NW Cuba Tuesday morning, and move E of the area by early Wednesday
evening. Strong high pressure in the wake of the front will bring
fresh to strong northerly winds over much of forecast waters from
early on Tuesday sunrise through late Thursday night. Winds will
diminish through Thursday afternoon as the high pressure shifts to
the NE Gulf. The high pressure will weaken on Friday as another
cold front moves across eastern Texas, and into the NW Gulf on
Friday night. The front will then reach from the NE Gulf to near
25N90W and the eastern Bay of Campeche by late on Saturday
followed by strong high pressure to once again bring another round
of strong northerly flow across much of the basin, with northerly
winds expected to reach gale force in the far SW Gulf portion.
