Synopsis for the Gulf of Mexico
1010 PM EDT Thu Oct 19 2017

.SYNOPSIS...High pressure will continue to extend from the Mid-
Atlantic states southwestward to the northern Gulf of Mexico
waters through Saturday night, then weaken and shift eastward
early on Sunday as a cold front moves off the Texas coast.
Fresh E winds across the northern Gulf waters will become SE
across the NW Gulf waters overnight tonight, continue through
Saturday, then become light southerly flow just ahead the cold
front that will move off the Texas coast on Sunday morning.
The front is expected to reach from near Mobile Alabama to the
eastern Bay of Campeche early on Monday, from near Sarasota
Florida to the northern Yucatan Peninsula Tuesday morning and
from near Fort Myers Florida to the NE Yucatan Peninsula by
Tuesday evening. Strong high pressure will build southeastward
across the area in the wake of the front with fresh to locally
strong northerly winds spreading from W to E across the forecast
waters.
