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.
