Introduction: Outdoor Warning System Survey: Technology and Policy Considerations

4% of survey complete.

Tornado fatalities during 2011 totaled 551, the most tornado fatalities in a single year since 1936. Follow-up National Weather Service (NWS) assessments cited outdoor siren policy as an area of confusion for the public, and NOAA “Weather Ready Nation” colloquia have since recommended consideration of a set of siren policy guidelines.

This outdoor warning system survey is a first step towards understanding what siren technologies are deployed and the current policies guiding the operation of sirens. We are seeking information from a wide variety of siren networks nationwide to fully understand regional variability and policy considerations, so your participation in this important study is critical.

Please note that all information you provide will be kept confidential and will not be used for any purpose other than academic research. We ask that you include your contact and address information to help us understand any complex situations you might describe; however, you may omit this information if you so choose.

If you have any questions or concerns about this survey, please contact Dr. Jerry Brotzge ( of the University of Oklahoma at (405) 325-5571 or Dr. Bill Donner ( of Indiana University of Pennsylvania at (724) 357-2730.

If possible, please complete this survey by November 15.

We very much appreciate your time in completing this survey – thank you!
