   Areas affected...central AL

   Concerning...Tornado Watch 18...

   Valid 121900Z - 122000Z

   The severe weather threat for Tornado Watch 18 continues.

   SUMMARY...A strong to intense tornado (~EF3) is likely ongoing
   across central AL and after tornado demise, a wind-damage risk will
   likely continue into east-central AL.

   DISCUSSION...KBMX radar imagery shows an intense low-level
   mesocyclone moving through an adequately moist/moderately buoyant
   airmass across central AL.  SPC data analytics indicates a
   strong/intense tornado is likely ongoing across Autauga County, AL. 
   The area VAD/s show large hodographs with 300 m2/s2 0-0.5 km
   effective SRH.  The strong shear/buoyancy will likely aid in
   sustaining the supercell after eventual tornado demise once the
   squall line overtakes the supercell.  Nonetheless, a significant
   wind-damage threat and some tornado risk will likely continue into
   eastern AL through the mid afternoon.
