SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
827 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.
