PRECIPITATION POTENTIAL ON MONDAY. WILL HAVE PRECIPITATION OVER
NORTHEAST FLORIDA...DUE TO POSSIBLE OUTER MOISTURE BANDS FROM
POTENTIAL TROPICAL SYSTEM.

PRECIPITATION COVERAGE. WITH INCREASING ONSHORE FLOW...MOST LOCATIONS

MORNING. NORTHEAST WINDS WILL BEGIN TO INCREASE ON SUNDAY BEHIND
A BACKDOOR COLD FRONT WITH AN EXTENDED PERIOD OF ONSHORE FLOW
EXPECTED THROUGH THE MIDDLE OF NEXT WEEK. SMALL CRAFT ADVISORY
CONDITIONS WILL BE POSSIBLE EARLY NEXT WEEK AS THE PRESSURE
GRADIENT TIGHTENS WITH HIGH PRESSURE BUILDING DOWN THE COAST AND A
POSSIBLE TROPICAL SYSTEM PASSING OVER THE WRN ATLC WATERS BUT
LARGE UNCERTAINTY REMAINS ON THE EXACT TRACK. SEAS WILL BE
DEPENDENT ON STRENGTH AND TRACK OF ANY TROPICAL SYSTEM BUT FOR NOW
