SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
238 PM EST Sat Nov 18 2017

.SYNOPSIS...Atlantic high pressure across Florida to the Gulf of
Mexico slides southward through tonight then exits east Sunday as a
cold front moves into northern Florida. The Front tracks down the
state during Sunday and slips south of the Florida Keys early Monday.
High pressure behind the front builds in across the Gulf region and
treks east to the Atlantic by midweek...allowing the front to lift
north from the Keys. A low pressure area may form on the front toward
the end of the week...introducing some uncertainty into later
forecasts. Winds shift with the frontal passage and reach cautionary
to advisory speeds but gradually subside as the high builds in then
moves east.
