   Areas affected...southern Florida

   Concerning...Tornado Watch 545...

   Valid 272237Z - 280030Z

   The severe weather threat for Tornado Watch 545 continues.

   SUMMARY...The threat of supercells within the outer bands of Ian
   will continue to pose a tornado risk through the evening.

   DISCUSSION...A northwest-southeast oriented band of supercells
   continues to translate north across southern FL, with periodic
   strong rotation and brief tornadoes. These storms may eventually
   encounter slightly lower boundary-layer theta-e as they gain
   latitude. However, advection of upper 70s F to near 80 F dewpoints
   will persist to the south, with slowly veering surface winds.

   Deep-layer effective shear is oriented quite favorably in relation
   to the outer convective bands, with a large component across the
   bands. This should aid supercellular storm mode, and the possibility
   of rightward motions relative to the weaker echoes, maximizing SRH.
