Dallas Center Renews its StormReady Status

July 17, 2014 Dallas Center completed a renewal of their StormReady® status.  Dallas Center completed a set of rigorous criteria necessary to earn the distinction of being StormReady®.  Dallas Center initially became StormReady® three years ago in 2008.

StormReady® is a voluntary program that provides communities and universities with clear-cut advice from a partnership between local National Weather Service forecast offices and state and local emergency managers. To be recognized as StormReady®, a community or college must:

  • Establish a 24-hour warning point and emergency operations center;
  • Have more than one way to receive severe weather forecasts and warnings and to alert the public
  • Create a system that monitors local weather conditions
  • Promote the importance of public readiness through community seminars;
  • Develop a formal hazardous weather plan, which includes training severe weather spotters and holding emergency exercises.

The National Weather Service congratulates Dallas Center on maintaining their StormReady® status.
