Synopsis for the Gulf of Mexico
954 PM EDT Fri Oct 20 2017

.SYNOPSIS...High pressure will continue to extend from the Mid-
Atlantic states southwestward to the northern Gulf of Mexico
waters through Sunday night, as a cold front moves off the Texas
coast. Fresh E winds in the northern Gulf waters will become SE
across the NW Gulf waters this morning, continue through
Saturday, then become light southerly flow just ahead of the
Sunday evening cold front for the Texas coast. The front is
expected to reach from near Apalachicola FLorida to the eastern
Bay of Campeche by Monday evening, from near Fort Myers Florida
to the N central 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.
