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

HURRICANE MATTHEW WILL CONTINUE TO TRACK NEAR THE SOUTHEAST SOUTH
CAROLINA COAST INTO LATE MORNING. THE CENTER OF THE CATEGORY TWO
HURRICANE SHOULD REMAIN JUST OFFSHORE NEAR THE CHARLESTON COUNTY COAST
THIS MORNING...THEN IS EXPECTED TO MOVE NORTHEAST TO A POSITION OFF
THE SOUTHEAST NORTH CAROLINA COAST BY THIS EVENING.

TROPICAL STORM FORCE WINDS WILL PERSIST ACROSS MUCH OF SOUTHEAST SOUTH
CAROLINA AND SOUTHEAST GEORGIA THIS MORNING WITH HURRICANE FORCE WINDS
ALONG THE COAST.

SUSTAINED WINDS ALONG THE COAST COULD REACH AS HIGH AS 60 TO 70 MPH
WITH GUSTS UP TO 90 TO 100 MPH...MAINLY AT COASTAL COMMUNITIES IN
CHARLESTON COUNTY. FARTHER INLAND...ESPECIALLY ALONG AND EAST OF
INTERSTATE 95...SUSTAINED WINDS OF 35 TO 55 MPH WITH GUSTS TO 65 MPH
ARE POSSIBLE. LOCATIONS WELL INLAND...MAINLY WEST OF INTERSTATE 95...
COULD SEE SUSTAINED WINDS OF 30 TO 40 MPH WITH GUSTS TO 55 MPH.
WIDESPREAD POWER OUTAGES ARE ALREADY BEING REPORTED ACROSS THE AREA
AND ADDITIONAL OUTAGES ARE EXPECTED. EXTENSIVE DAMAGE TO TREES AND
OTHER STRUCTURES WILL OCCUR...ESPECIALLY NEAR THE COASTS.

WINDS WILL BEGIN TO TAPER OFF THIS AFTERNOON ACROSS SOUTHEAST GEORGIA
AND THIS EVENING OVER SOUTHERN SOUTH CAROLINA.

STORM TOTAL RAINFALL AMOUNTS OF 8 TO 14 INCHES ARE EXPECTED ACROSS
COASTAL AREAS WITH LOCALLY HIGHER TOTALS. FARTHER INLAND STORM TOTALS
WILL RANGE FROM 4 TO 8 INCHES WITH LOCALLY HIGHER TOTALS. THIS HEAVY
RAINFALL WILL RESULT IN EXTENSIVE FRESH WATER FLOODING...ESPECIALLY
NEAR THE COAST WITHIN A FEW HOURS OF THE HIGH TIDES.

STORM SURGE INUNDATION OF 6 TO 9 FEET ABOVE GROUND LEVEL IS EXPECTED
THROUGH THIS MORNING. THE COMBINATION OF STORM SURGE AND WAVES COULD
RESULT IN MAJOR COASTAL FLOODING AND SEVERE BEACH EROSION. HOMES...
STRUCTURES AND ROADS NEAR BEACHES COULD BE COMPROMISED. DANGEROUS RIP
CURRENTS AND LARGE WAVES WILL MAKE FOR TREACHEROUS SURF CONDITIONS
THROUGH THE WEEKEND.

AN ISOLATED TORNADO WILL BE POSSIBLE THIS MORNING ACROSS COASTAL AREAS
IN CHARLESTON COUNTY...BUT THE THREAT WILL DECREASE BY LATE MORNING
HOURS.

      MAY BE UNINHABITABLE FOR WEEKS OR MONTHS.

      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
