What is a Severe Thunderstorm Watch?

 

   The National Weather Service in Bismarck serves 36 counties and 3 Tribal Nations across western and central North Dakota.

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

  • Wind gusts of 58 mph or greater and/or
  • Hail of one inch in diameter or larger

    In addition to damaging winds and large hail, severe thunderstorms are also capable of producing tornadoes, flash flooding and                deadly lightning.

 

                                                                      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.
