AREAS AFFECTED...CNTRL/NRN FL

CONCERNING...TORNADO WATCH 473...474...

VALID 131121Z - 131145Z

WT473 HAS A 12Z EXPIRATION AND AFTER COLLABORATION WITH LOCAL
WFO/S...A DECISION WILL BE MADE WHETHER TO ISSUE A NEW WW.  

DURING THE PAST SEVERAL HOURS...THE PRIMARY CONVECTIVE BAND
ASSOCIATED WITH ALBERTO HAS BEEN ROTATING NEWD THROUGH CNTRL/NRN FL.
 THIS BAND HAS LARGELY MOVED OFFSHORE...EXCEPT THE SRN END THAT
TRAILS SWWD ACROSS THE CAPE AND INTO THE NAPLES AREA.  PER LATEST
VWP FROM TBW/MLB...THE LOW-LEVEL WIND FIELDS HAVE VEERED ACROSS
CNTRL FL AND EFFECTIVELY LESSENED THE 0-1KM SRH.  FARTHER TO THE
N...JAX VWP REMAINS FAVORABLY SHEARED FOR TORNADOES.  BUT...SATL
SHOWS A CONSIDERABLE AMOUNT OF DRY AIR WRAPPING NEWD ACROSS THE
REGION.  THIS MAY PROVE DETRIMENTAL IN SUPPORTING SUSTAINED BANDING
STRUCTURES/CONVECTION. 

PRIND THAT THERE WILL BE LOW PROBABILITIES FOR MAINLY AN ISOLD
DAMAGING WIND GUST ACROSS CNTRL FL THROUGH LATE MORNING.  FARTHER
N...WITHIN THE RICHER HELICITY ENVIRONMENT...GIVEN A SUSTAINED
STORM...ISOLD TORNADOES WILL STILL BE POSSIBLE WITHIN WT474.
