A tornado warning is issued by the National Weather Service when a tornado has been sighted or indicated on radar.  The siren will be sounded if a tornado or tornado producing storm is moving toward the Haven area.  In a power outage, emergency vehicles will provide street by street warning with sirens or public address systems.

  • If driving a vehicle when a tornado warning sounds or you see a tornado, exit your vehicle and lay flat in a ditch, depression or other protected area.  If the tornado is over a half mile away you may drive at a right angle away from it if possible.
