SITUATION OVERVIEW
------------------

HURRICANE MATTHEW IS ANTICIPATED TO TRACK NORTHWEST FROM THE BAHAMAS
TOWARD CENTRAL FLORIDA THROUGH TODAY...BEFORE TURNING NORTH AND
TRACKING NEAR THE GEORGIA COAST FRIDAY NIGHT INTO SATURDAY. THE
HURRICANE COULD CONTINUE TO TRACK NEAR THE SOUTH CAROLINA COAST OR
COULD TURN TOWARD THE NORTHEAST SATURDAY AND SATURDAY NIGHT. MATTHEW
COULD PASS CLOSE TO THE GEORGIA AND SOUTH CAROLINA COAST AS A CATEGORY
2 OR CATEGORY 3 HURRICANE. THE MOST SIGNIFICANT IMPACTS FROM MATTHEW
WILL LIKELY SPREAD NORTH ACROSS THE AREA AHEAD/ALONG THE PATH OF THE
STORM...POSSIBLY REACHING SOUTHEAST GEORGIA FRIDAY AFTERNOON AND
SOUTHEAST SOUTH CAROLINA AS EARLY AS FRIDAY EVENING.

TROPICAL STORM FORCE WINDS ARE FORECAST TO REACH COASTAL SOUTHEAST
GEORGIA FRIDAY AFTERNOON...THEN NORTH ALONG COASTAL SOUTHEAST SOUTH
CAROLINA FRIDAY EVENING AND FRIDAY NIGHT. SUSTAINED WINDS COULD REACH
AS HIGH AS 40-50 MPH INLAND TO 60-70 MPH NEAR THE COAST. THESE WINDS
COULD DAMAGE TREES AND WEAKER STRUCTURES AND RESULT IN WIDESPREAD
POWER OUTAGES. THERE IS AN INCREASING RISK OF SUSTAINED HURRICANE
FORCE WINDS ALONG THE IMMEDIATE COASTLINE IF MATTHEW MAINTAINS A CLOSE
PROXIMITY TO THE COAST. THE THREAT FOR HURRICANE FORCE WINDS WILL
INCREASE FOR COASTAL LOCATIONS LATE FRIDAY NIGHT INTO SATURDAY...THEN
LOWER AS MATTHEW SHIFTS AWAY FROM THE COAST. THE THREAT FOR TROPICAL
STORM FORCE WINDS OR HIGHER SHOULD BEGIN TO DECREASE SATURDAY NIGHT
INTO EARLY MORNING SUNDAY.

THE LATEST TRACK OF MATTHEW COULD PRODUCE HEAVY RAINFALL OVER THE
AREA...ESPECIALLY NEAR THE COAST. STORM TOTAL RAINFALL AMOUNTS RANGING
FROM 8 TO 14 INCHES WITH ISOLATED GREATER AMOUNTS ARE POSSIBLE TONIGHT
INTO SUNDAY MORNING. THESE RAINFALL AMOUNTS COULD RESULT IN EXTENSIVE
FRESH WATER FLOODING...ESPECIALLY DURING THE TIMES OF HIGH TIDE AND
MAXIMUM STORM SURGE NEAR THE COAST THIS WEEKEND.

THE MOST LIKELY STORM SURGE SCENARIO ASSOCIATED WITH HURRICANE MATTHEW
IS 7 TO 9 FEET WITH ISOLATED LOCATIONS UP TO 11 FEET OF WATER ABOVE
GROUND LEVEL IN SOUTHEAST GEORGIA AND 3 TO 5 FEET WITH ISOLATED
LOCATIONS UP TO 8 FEET OF WATER ABOVE GROUND LEVEL IN SOUTHEAST SOUTH
CAROLINA. STORM SURGE FORECASTS COULD BE HIGHER/LOWER DEPENDING ON THE
TRACK AND INTENSITY OF MATTHEW AS IT APPROACHES THE AREA THIS WEEKEND.
THE COMBINATION OF STORM SURGE AND WAVES COULD RESULT IN MAJOR COASTAL
FLOODING AND SEVERE BEACH EROSION. HOMES...STRUCTURES AND ROADS
NEAR/ALONG BEACHES COULD BE COMPROMISED. THE THREAT FOR DANGEROUS RIP
CURRENTS WILL ALSO INCREASE WITH THE APPROACH OF MATTHEW LATE WEEK
INTO THE WEEKEND.

THE THREAT FOR TORNADOES WILL REMAIN LOW THIS WEEKEND BECAUSE THE
CENTER OF HURRICANE MATTHEW IS ANTICIPATED TO REMAIN OFFSHORE.
HOWEVER...THERE IS A RISK OF AN ISOLATED WATERSPOUT MOVING ONSHORE
FRIDAY INTO SATURDAY UNTIL MATTHEW SHIFTS FURTHER OFFSHORE LATER
SATURDAY.
