    A Severe Thunderstorm is defined as a thunderstorm capable of producing:

Severe Thunderstorm Safety Tips

  • Stay away from windows!! Flying debris and wind driven hail can break windows sending shards of glass through the air.
  •  
  • If camping, seek shelter inside a sturdy building as campers/RVs can be easily flipped by damaging winds associated with severe thunderstorms. Falling trees and large hail can easily penetrate the thin walls of a tent.
  •  
  • Those in mobile homes should go to their designated storm shelter. Destructive straight-line winds are capable of causing significant damage to mobile homes.
  • Severe thunderstorms are capable of producing tornadoes with little warning. Stay tuned to NOAA Weather Radio or your favorite media outlet for frequent weather updates.
