AREAS AFFECTED...CNTRL/SRN FL PENINSULA

CONCERNING...TORNADO WATCH 749...

VALID 131504Z - 131630Z

GREATEST POTENTIAL FOR ISOLATED TORNADOES THROUGH 16-17Z APPEARS TO
BE INTERIOR SRN PENINSULA W/S OF LAKE OKEECHOBEE.

CONVECTIVE BAND ATTENDANT TO HURRICANE CHARLEY HAS INTENSIFIED OVER
THE PAST HOUR FROM PORTIONS OF MIAMI-DADE/MONROE COUNTIES NNWWD INTO
COLLIER AND HENDRY COUNTIES. SYNTHESIS OF LATEST OBJECTIVE FIELDS
AND OBSERVATIONAL DATA INDICATES A QUITE FAVORABLE ENVIRONMENT FOR
SUPERCELLS AND ISOLATED TORNADOES AS MLCAPES HAVE INCREASED TO
1000-1500 J/KG WITH 0-1KM SRH VALUES CURRENTLY 150-200 M2/S2.

THIS SAME GENERAL CORRIDOR IS EXPECTED TO REMAIN FAVORABLE FOR
ISOLATED TORNADOES WITH ANY SUBSEQUENT CONVECTIVE DEVELOPMENT
THROUGH 16-17Z. AS CHARLEY CONTINUES NWD THIS AFTERNOON...EXPECT A
CORRESPONDING SHIFT OF STRONGER SHEAR AND INSTABILITY TO LOCATIONS W
OF U.S. HIGHWAY 27 AND S OF INTERSTATE 4.
