   AREAS AFFECTED...S FL AND THE KEYS
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 250814Z - 251015Z
   
   SHOWERS AND THUNDERSTORMS WILL CONTINUE OVER THE NEXT SEVERAL HOURS
   ACROSS THIS REGION...WITH A BRIEF WATERSPOUT/TORNADO OR LOCALLY
   ENHANCED DOWNDRAFT POSSIBLE.  HOWEVER...ISOLATED/LOW-END THREAT
   SUGGESTS THAT WATCH WILL LIKELY NOT BE REQUIRED.
   
   LATEST MIAMI AND KEY WEST RADARS REVEAL SCATTERED CELLULAR
   CONVECTION ON THE SERN FRINGE OF A LARGER AREA OF MORE STRATIFORM
   RAIN.  RADAR REVEALS THAT SEVERAL OF THESE CELLS CONTINUE TO EXHIBIT
   WEAK ROTATION...CONSISTENT WITH AREA VAD WIND PROFILES WHICH SHOW
   MODEST -- BUT VEERING -- FLOW WITH HEIGHT.  
   
   WITH LOW-LEVEL LAPSE RATES QUITE WEAK AND MAGNITUDE OF THE FLOW
   LIMITED -- AND NOT EXPECTED TO STRENGTHEN SIGNIFICANTLY IN THE NEXT
   SEVERAL HOURS...EXPECT ANY SEVERE THREAT TO BE BRIEF AND ISOLATED AT
   BEST.  GREATEST POTENTIAL APPEARS TO BE FOR AN ISOLATED WATERSPOUT
   TO MOVE ONSHORE OVER THE KEYS.
