   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 11
   NWS Storm Prediction Center Norman OK
   405 PM CDT Sun Mar 18 2018

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     North-central and East Texas

   * Effective this Sunday afternoon and evening from 405 PM until
     1100 PM CDT.

   * Primary threats include...
     Scattered large hail and isolated very large hail events to 3
       inches in diameter possible
     Isolated damaging wind gusts to 70 mph possible
     A tornado or two possible

   SUMMARY...At least isolated severe storms are expected to increase
   initially across central Texas in the general vicinity of Interstate
   35 this afternoon, and subsequently spread eastward toward East
   Texas by evening. Large hail should be the most common hazard, but
   locally damaging winds and/or a tornado cannot be ruled out,
   particularly as low-level shear increases this evening.

   The severe thunderstorm watch area is approximately along and 105
   statute miles east and west of a line from 35 miles north of Fort
   Worth TX to 25 miles southeast of Huntsville TX. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU1).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for 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. Severe thunderstorms can and occasionally do produce
   tornadoes.

   &&

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   3 inches. Extreme turbulence and surface wind gusts to 60 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
   26025.
