SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
254 PM EDT Tue Oct 17 2017

.SYNOPSIS...High pressure will build into the mid-Atlantic region
and remain in place through the rest of the week, with northeast
winds increasing to cautionary or advisory levels for all of the
coastal waters. A Small Craft Advisory will be in effect for the Gulf
waters from Englewood to the Suwannee River and including Tampa Bay
through Wednesday. There could be a period of sub-advisory winds
during the day, but they should then increase again Wednesday night,
so the advisory may need to be extended further out in time.
