AREAS AFFECTED...SC...SRN NC

CONCERNING...TORNADO WATCH 843...

VALID 271924Z - 272100Z

THE TORNADO THREAT WILL CONTINUE THIS AFTERNOON AS RAINBANDS MOVE
NNWWD ACROSS THE CAROLINAS. WW WILL BE REPLACED WITHIN THE HOUR AND
BE ADJUSTED NORTH INTO NC.

THE CENTER OF TROPICAL DEPRESSION JEANNE IS CURRENTLY OVER SCNTRL GA
WITH RAINBANDS ORIENTED SSE TO NNW OUT TO ABOUT 200 MILES FROM THE
CENTER. AT THE SFC...THE MOIST TONGUE IS EXPANDING ACROSS SC AND
DEWPOINTS HAVE RISEN INTO THE MID 70S F DUE TO STRONG ONSHORE FLOW.
WITH THE INCREASING SFC DEWPOINTS AND WARMING TEMPS...MLCAPE VALUES
NOW RANGE FROM 1000 TO 1500 J/KG ACROSS ERN SC AND SRN NC. IN
ADDITION...THE BACKED SFC FLOW IS RESULTING IN STRONGLY VEERED WIND
PROFILES BELOW 700 MB. THIS COMBINED WITH THE STRONG LOW-LEVEL SHEAR
AND LOW LCL HEIGHTS WILL BE FAVORABLE FROM TORNADOES. THE TORNADO
POTENTIAL WILL BE GREATEST WITH THE MORE INTENSE ROTATING CELLS THAT
DEVELOP IN THE OUTER RAINBANDS.
