Olmsted County Emergency Management maintains three (3) thresholds for activating the OWSS:

RADAR indicated tornado or confirmed tornado sighting by a trained and registered SkyWarn Storm Spotter
Hail of 2 inches or greater in diameter (RADAR indicated or SkyWarn Spotter report)
Winds of 70+ MPH

If you are outside when you hear the Outdoor Warning Siren System activate, immediately seek shelter in the lowest level or interior room of a sturdy building and seek further weather information via radio, television, or a trusted weather application on your smartphone. GET IN AND TUNE IN!
