   URGENT - IMMEDIATE BROADCAST REQUESTED
   Tornado Watch Number 480
   NWS Storm Prediction Center Norman OK
   735 PM EDT Tue Aug 31 2021

   The NWS Storm Prediction Center has issued a

   * Tornado Watch for portions of 
     Extreme north-central North Carolina
     Western and central Virginia

   * Effective this Tuesday night and Wednesday morning from 735 PM
     until 300 AM EDT.

   * Primary threats include...
     A couple tornadoes possible
     Isolated damaging wind gusts to 70 mph possible

   SUMMARY...One supercell formed and quickly became tornadic in the
   Blacksburg area in the past hour, and overall tornado potential
   should increase through the evening.  The threat should spread
   northeastward over the watch area, as additional thunderstorms
   develop in a favorably unstable air mass and interact with a
   warm-frontal zone, where low-level shear is maximized.

   The tornado watch area is approximately along and 40 statute miles
   either side of a line from 30 miles southwest of Roanoke VA to 40
   miles east northeast of Charlottesville VA. For a complete depiction
   of the watch see the associated watch outline update (WOUS64 KWNS
   WOU0).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Tornado Watch means conditions are favorable for
   tornadoes and severe thunderstorms in and close to the watch
   area. Persons in these areas should be on the lookout for
   threatening weather conditions and listen for later statements
   and possible warnings.

   &&

   AVIATION...Tornadoes and a few severe thunderstorms with hail
   surface and aloft to 0 inches. Extreme turbulence and surface wind
   gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean
   storm motion vector 23025.
