JACKSON, Wyo. — The Teton County Emergency Management will be conducting tests of the county’s outdoor warning siren system today, Wednesday, Oct. 27. You may hear short one-minute blasts from the outdoor warning sirens throughout the day.

The sirens are used to alert the community to seek further information about different types of hazards, including tornados, hazardous materials spills, dam failure, wildlife evacuation and more.

In Teton County, outdoor warning sirens are tested periodically for a one-minute wail. If it is a real emergency, sirens will sound for a three-minute wail. Outdoor warning sirens may be activated for any emergency where there is an immediate life threat to a significant portion of the population near the siren.

Sirens are located in Hoback Junction, at Fire Station 7 in Adam’s Canyon, on School Bus Barn on Gregory Lane, Fire Station 1 in Jackson, Fire Station 6 in Teton Pines, Fire Station 2 in Wilson, and on Tram Tower 1 in Teton Village.

If you hear an outdoor warning siren, tune to local EAS radio stations, cable television (channels 8 and 5,08 on Charter Cable; channels 29 and 36 over-the-air)  NOAA Weather Radio, local news sources, and/or your cell phone for a Nixle or Wireless Emergency Alert message advising what is happening, where it is happening, and what the recommended actions are.
Radio stations include:

  • FM 88.3 KMLT (broadcasts EAS message only; will not have live follow-up reporting on emergencies)
  • FM 89.1 KHOL
  • AM 1340 KSGT
  • FM 93.5 KJAX
  • FM 95.3 KZJH
  • FM 96.9 KMTN

Outdoor warning sirens are not designed to warn people who are indoors, and audible ranges assume a listener is outdoors. This map does not include outdoor warning sirens owned by private entities, such as golf course,  nor does it include the siren at Jackson Hole Airport, which is not maintained by Teton County Emergency Management.
