SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
242 PM EST Wed Dec 13 2017

.SYNOPSIS...High pressure is building into the region from the west
which has allowed for the winds to veer and decrease to the north-
northwest around 10 knots this afternoon. As this high slips
eastward, the winds will further decrease by late this evening and
then shift to the southwest as the high moves east of Florida on
Thursday. A weak front moves through on Friday bringing a slight
chance of showers over the coastal waters. Winds will veer to the
north and then northeast behind this front on Saturday. High pressure
settles back into the area through Sunday and will produce an
easterly component wind over the coastal waters, but remaining 15
knots or less by the beginning of next week. So outside of any shower
activity on Friday, the conditions over the coastal waters should be
favorable for any boating activities.
