TORNADO WATCH STILL IN EFFECT

URGENT - IMMEDIATE BROADCAST REQUESTED
   Tornado Watch Number 17
   NWS Storm Prediction Center Norman OK
   650 PM CST Sat Jan 21 2017

   The NWS Storm Prediction Center has issued a

   * Tornado Watch for portions of 
     Central and southern Alabama
     Western and central Florida Panhandle
     Small part of southeastern Mississippi
     Coastal Waters

   * Effective this Saturday night and Sunday morning from 650 PM
     until 300 AM CST.

   ...THIS IS A PARTICULARLY DANGEROUS SITUATION...

   * Primary threats include...
     Several tornadoes and a few intense tornadoes likely
     Scattered damaging winds and isolated significant gusts to 75
       mph possible
     Isolated very large hail events to 2.5 inches in diameter
       possible

   SUMMARY...A cluster of storms now moving into extreme southwestern
   Alabama is the first of what likely will be several areas of severe
   weather moving across this watch overnight.  As a warm front moves
   northward across the region, conditions will moisten and destabilize
   considerably amidst strong vertical shear.  The resulting parameter
   space is one often associated with long-lasting, intense tornadoes
   rated EF2 or greater.

   The tornado watch area is approximately along and 100 statute miles
   north and south of a line from 80 miles north of Mobile AL to 50
   miles south of Columbus GA. For a complete depiction of the watch
   see the associated watch outline update (WOUS64 KWNS WOU7).

   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.

   &&

   OTHER WATCH INFORMATION...CONTINUE...WW 15...WW 16...

   AVIATION...Tornadoes and a few severe thunderstorms with hail
   surface and aloft to 2.5 inches. Extreme turbulence and surface wind
   gusts to 65 knots. A few cumulonimbi with maximum tops to 450. Mean
   storm motion vector 25030.
