AREAS AFFECTED...ERN FL PANHANDLE EWD INTO S CENTRAL AND SERN GA/NRN
FL PENINSULA

CONCERNING...TORNADO WATCH 776...

VALID 272043Z - 272215Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 776 CONTINUES.

BAND OF RAIN WITH EMBEDDED CONVECTIVE CELLS CONTINUES SPREADING EWD
ACROSS THE SOUTHEAST CONUS/ERN GULF...THROUGH A VERY WEAKLY UNSTABLE
BUT STRONGLY SHEARED ENVIRONMENT. AN ISOLATED CELL NOW MOVING INTO
COASTAL TAYLOR COUNTY FL HAS HAD A HISTORY OF WEAK ROTATION...BUT
ROTATION CONTINUES TO DIMINISH AS THE CELL MOVES ONSHORE.

A VERY ISOLATED/LIMITED THREAT FOR A BRIEF TORNADO SHOULD CONTINUE
ACROSS ERN PORTIONS OF WW 776...AND WITH TIME ACROSS SERN GA AND
ADJACENT N FL...AS THIS AREA OF CONVECTION SHIFTS EWD WITH TIME.
HOWEVER...POTENTIAL APPEARS SUFFICIENTLY LIMITED THAT A NEW WW IS
NOT ANTICIPATED ATTM.
