TUESDAY THROUGH SUNDAY...
A STRONG LOW PRESSURE SYSTEM IS FORECAST TO DEVELOP BY WEDNESDAY. THE EXACT STRENGTH AND TRACK OF THE SYSTEM WILL DETERMINE THE SEVERITY OF THE IMPACT... A SWATH OF VERY HEAVY RAIN IS ANTICIPATED TO ACCOMPANY THIS SYSTEM. RAINFALL TOTALS THROUGH WEDNESDAY NIGHT COULD REACH 6 OR MORE INCHES IN SOME AREAS. IN ADDITION VERY STRONG SOUTHERLY WINDS ARE EXPECTED OVER THE COASTAL WATERS BEGINNING LATE TUESDAY AND CONTINUING INTO WEDNESDAY. AS A RESULT A GALE WATCH HAS BEEN ISSUED FOR THIS TIME PERIOD.

STORM TIDES OF 3 TO 4 FEET WILL BE POSSIBLE FROM FRANKLIN COUNTY WESTWARD.

IN THE WAKE OF THIS STORM...RIVER FLOODING MAY BECOME A CONCERN OVER PORTIONS OF THE REGION DUE TO RUNOFF FROM ANY EXCESSIVE RAINFALL.
