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 DURING FRIDAY AND SOUTHEAST SOUTH CAROLINA
AS EARLY AS FRIDAY EVENING.

TROPICAL STORM FORCE WINDS ARE FORECAST TO REACH COASTAL SOUTHEAST
GEORGIA FRIDAY AFTERNOON INTO EARLY EVENING...THEN NORTH ALONG COASTAL
SOUTHEAST SOUTH CAROLINA 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. THE THREAT FOR TROPICAL STORM FORCE WINDS OR HIGHER
SHOULD BEGIN TO DECREASE SATURDAY NIGHT INTO EARLY MORNING SUNDAY. THE
THREAT FOR HURRICANE FORCE WINDS WILL INCREASE FOR LOCATIONS NEAR THE
COAST LATE FRIDAY NIGHT INTO SATURDAY...THEN LOWER AS MATTHEW SHIFTS
AWAY FROM THE COAST.

THE LATEST TRACK OF MATTHEW COULD PRODUCE HEAVY RAINFALL OVER THE
AREA...ESPECIALLY NEAR THE COAST. STORM TOTAL RAINFALL AMOUNTS RANGING
FROM 8-14 INCHES WITH ISOLATED GREATER AMOUNTS POSSIBLE THURSDAY NIGHT
THROUGH SATURDAY NIGHT. 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 4 TO 8 FEET OF WATER ABOVE GROUND LEVEL. 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 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.

POTENTIAL IMPACTS

* WIND:
PREPARE FOR LIFE-THREATENING WIND HAVING POSSIBLE DEVASTATING IMPACTS
ACROSS COASTAL COUNTIES. POTENTIAL IMPACTS IN THIS AREA
INCLUDE:
    - STRUCTURAL DAMAGE TO STURDY BUILDINGS, SOME WITH COMPLETE ROOF
      AND WALL FAILURES. COMPLETE DESTRUCTION OF MOBILE HOMES. DAMAGE
      GREATLY ACCENTUATED BY LARGE AIRBORNE PROJECTILES. LOCATIONS
      MAY BE UNINHABITABLE FOR WEEKS OR MONTHS.
    - UNSAFE TO SHELTER EVEN IN WELL-CONSTRUCTED BUILDINGS.
      IMPOSSIBLE TO VENTURE OUTSIDE DUE TO FALLING OBJECTS AND
      AIRBORNE PROJECTILES.
    - NUMEROUS LARGE TREES SNAPPED OR UPROOTED ALONG WITH FENCES AND
      ROADWAY SIGNS BLOWN OVER.
    - MANY ROADS IMPASSABLE FROM LARGE DEBRIS, AND MORE WITHIN URBAN
      OR HEAVILY WOODED LOCATIONS. MOST OR ALL BRIDGES AND ACCESS
      ROUTES IMPASSABLE.
    - WIDESPREAD DAMAGE TO POWER AND COMMUNICATIONS INFRASTRUCTURE
      WITH RESULTING OUTAGES POSSIBLY LASTING FOR WEEKS OR LONGER.
      GAS LEAKS AND FALLEN ELECTRIC WIRES POSE A THREAT TO LIFE.

    - FLOOD WATERS COULD ENTER MANY STRUCTURES WITHIN MULTIPLE
      COMMUNITIES; SOME STRUCTURES BECOME UNINHABITABLE OR ARE WASHED
      AWAY. FLOOD WATERS COULD COVER MULTIPLE ESCAPE ROUTES. STREETS
      AND PARKING LOTS BECOME RIVERS OF MOVING WATER WITH UNDERPASSES
