SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
350 AM EST Fri Dec 15 2017

.SYNOPSIS...High pressure over the Florida Straits extending east
into the western Atlantic will move east-southeast today as a weak
cool front across the southeastern states sinks southeast toward
north Florida during the afternoon. Ahead of the front expect
southwest to west winds around 10 knots with slight seas and a slight
chance of a few showers over the waters today. Tonight winds will
shift to the northeast and east as the front move south and stalls
and washes out across the south-central Gulf waters on Saturday as
surface high pressure builds in over the southeastern states. During
the latter part of the weekend and into early next week winds will
veer to the southeast and south with a slight uptick in speeds as the
pressure gradient tightens some between high pressure offshore the
mid Atlantic coast and weak areas of low pressure developing along a
frontal boundary over the lower Mississippi valley. Lighter
southeast to south winds will return on Tuesday as the high sinks
southeast and extends west across the central peninsula. Wind and
seas should remain below 15 knots and 5 feet through the period with
no headlines expected.
