TORNADO THREAT CONTINUES ACROSS CENTRAL AND SRN FL IN ADVANCE OF
HURRICANE WILMA.  NEW TORNADO WATCH WILL BE ISSUED WITHIN THE
HOUR...WHICH WILL COVER ALL OF CENTRAL AND SRN FL.

A MORE WELL-DEFINED OUTER BAND HAS NOW SPREAD EWD INTO THE
KEYS...WITH ROTATING STORMS NOW EVIDENT JUST OFF THE SWRN FL COAST. 
ADDITIONALLY...TORNADOES CONTINUE TO OCCUR WITHIN STORMS OCCURRING
BETWEEN TBW AND MLB -- ALONG NEARLY STATIONARY BAROCLINIC ZONE.

EVENING EYW RAOB SHOWS VERY STRONG WIND FIELD...AND SUBSTANTIAL
INSTABILITY OWING TO 7 C/KM LAPSE RATES IN THE 700 TO 500 MB LAYER. 
GIVEN THE DEGREE OF INSTABILITY AND INTENSIFYING WIND FIELD WITH THE
APPROACH OF WILMA...EXPECT TORNADO THREAT TO INCREASE WITH TIME
ACROSS THE SRN 2/3 OF THE FL PENINSULA.  WITH SEVERAL COUNTIES ALONG
THE E COAST OF FL NOT IN A TORNADO WATCH ATTM...AND WITH THREAT
EXPECTED TO PERSIST THROUGH THE OVERNIGHT HOURS...NEW WW WILL BE
