.SYNOPSIS...
A strong cold front will move south of the waters this afternoon.
Gale warnings and small craft advisories are in effect for a strong
northeasterly wind surge behind the front today through Wednesday.
Scattered showers and possibly a thunderstorm are expected today
through tonight mainly across the northeast Florida waters. High
pressure will then begin to build in from the north Wednesday night
resulting in winds lowering but seas will remain elevated and rough.
Another cold front will enter the southeast states on Friday night,
crossing our local waters on Saturday. Strong high pressure will
again build to the north of our area in the wake of this front,
resulting in another surge of onshore winds throughout our local
waters and possible Gale conditions during the weekend.
