   AREAS AFFECTED...FL PENINSULA
   
   CONCERNING...TORNADO WATCH 750...
   
   VALID 132006Z - 132130Z
   
   POTENTIAL FOR ISOLATED TORNADOES CONTINUES ACROSS WW AREA...WITH
   GREATEST THREAT OVER THE CNTRL PENINSULA THROUGH 21-22Z.
   
   AS OF 1946Z...TAMPA RADAR IMAGERY SHOWED THE CENTER OF CHARLEY
   APPROXIMATELY 25W OF FMY. WHILE INITIAL RAINBAND /COMPOSED AT TIMES
   OF SEVERAL SUPERCELLS/ HAS LIFTED N OF A ORL TO MLB
   LINE...SUBSEQUENT SUPERCELLS HAVE DEVELOPED IN SMALLER...MORE
   TRANSIENT BANDS SW OF TAMPA /NAMELY MANATEE...HARDY...DESOTO AND
   HIGHLANDS COUNTIES/. HERE...INFLUX OF MODERATELY UNSTABLE AIRMASS
   ALONG THE ERN PENINSULA /I.E. SBCAPES OF 2000-3000 J/KG/ IS
   ENCOUNTERING INCREASINGLY SHEARED ENVIRONMENT IN RIGHT FORWARD
   QUADRANT OF CHARLEY.
   
   ISOLATED TORNADOES WILL REMAIN POSSIBLE WITH ANY CONVECTIVE ELEMENTS
   ACROSS THE WW AREA THROUGH THE REMAINDER OF THE AFTERNOON.
   HOWEVER...IT APPEARS THAT THE GREATEST POTENTIAL THROUGH 21 OR 22Z
   WILL BE OVER THE CNTRL PENINSULA WHERE STRONGEST LOW-LEVEL SHEAR
   WILL BE CO-LOCATED WITH WRN EDGE OF GREATER INSTABILITY.
