1056 PM EST WED NOV 15 2006

...SEVERE WEATHER TO CONTINUE ACROSS THE AREA TONIGHT AND EARLY
THURSDAY...

A STRONG STORM SYSTEM WILL MOVE FROM THE TENNESSEE VALLEY INTO THE
EASTERN GREAT LAKES REGION TONIGHT THROUGH THURSDAY. THIS WILL
ALLOW A STRONG COLD FRONT TO PUSH THROUGH SOUTHERN SOUTH CAROLINA
AND SOUTHEAST GEORGIA LATE TONIGHT AND EARLY THURSDAY MORNING.

VERY STRONG WINDS JUST ABOVE THE SURFACE WILL PERSIST IN ADVANCE OF
THE COLD FRONT OVERNIGHT. AS THE SYSTEM MOVES ACROSS THE AREA
OVERNIGHT AND EARLY THURSDAY...A SQUALL LINE OF SHOWERS AND STRONGER
THUNDERSTORMS WILL AFFECT THE AREA. WIND FIELDS ARE QUITE SUPPORTIVE
OF SEVERE WEATHER...AND THE STRONGER CELLS THAT DEVELOP WILL ALLOW
THE STRONGER WINDS ALOFT TO MIX DOWN TO THE SURFACE. ASIDE FROM THE
DAMAGING WIND HAZARD...STRONG LOW LEVEL WIND SHEAR WILL ALSO RESULT
IN A CHANCE FOR ISOLATED TORNADOES ACROSS THE AREA.

THE BEST CHANCE FOR SEVERE WEATHER IS FROM 11 PM TO 1 AM MIDNIGHT IN
SUCH LOCATIONS AS SAVANNAH...DARIEN...PEMBROKE AND HAMPTON...FROM 1
AM TO 2 AM IN WALTERBORO...JACKSONBORO...BEAUFORT AND SAINT
GEORGE...AND FROM 2 TO 4 AM IN CHARLESTON...SUMMERVILLE AND MONCKS
CORNER.

BECAUSE WINDS WILL BE SO STRONG JUST ABOVE THE SURFACE...INTENSE
RAIN SHOWERS PRODUCING ABSOLUTELY NO LIGHTNING WILL BE CAPABLE OF
PRODUCING DAMAGING WINDS AT THE SURFACE AS WELL. THEREFORE...WIND
GUSTS GREATER THAN 58 MPH WILL BE POSSIBLE WITH LITTLE OR NO
WARNING...EVEN IN THE ABSENCE OF THUNDERSTORMS.

THIS IS A DANGEROUS SITUATION. STAY TUNED TO NOAA WEATHER RADIO ALL
HAZARDS...TV OR YOUR LOCAL NEWS SOURCE FOR THE LATEST STATEMENTS
FROM THE NATIONAL WEATHER SERVICE. BE SURE TO KEEP YOUR NOAA WEATHER
RADIO IN ALERT MODE AT ALL TIMES.
