   FLORIDA KEYS 88D RADAR CURRENTLY SHOWS HURRICANE CHARLIE JUST WEST
   OF KEY WEST WITH THE OUTER RAINBANDS SPREADING NWWD ACROSS THE SWRN
   TIP OF SOUTH FL. DRY AIR ENTRAINING BEHIND THE MAIN RAINBAND WILL
   MAKE CONDITIONS FAVORABLE FOR MORE ISOLATED SMALL SUPERCELLS ON THE
   TRAILING EDGE OF THE RAINBAND AS IT MOVES ACROSS SOUTH FL OVER THE
   NEXT FEW HOURS. STRONG LOW-LEVEL SHEAR WILL MAKE CONDITIONS RIGHT
   FOR AN ISOLATED TORNADO THREAT WITH MINI-SUPERCELLS AS THEY TRACK
   NWD INTO THE IMMEDIATE COASTAL SECTIONS. HEAVY RAIN WILL ALSO BE
   LIKELY AS THE HURRICANE MOVES TOWARD THE WEST COAST OF FL THROUGH
