Teton County Emergency Management will conduct a countywide outdoor warning siren drill on Friday, May 23, 2025, to test the effectiveness of its public alert system. Individual siren tests will begin at 9 a.m. and continue throughout the day, with a full-system test at noon, when all sirens will sound the Hi/Lo wail tone simultaneously. The drill is a test only, and no emergency exists; residents should not call dispatch. Emergency Management Coordinator Rich Ochs emphasized that sirens signal the need to pay attention to critical situations, serving as a vital alert tool when power or cell networks fail.
The public is encouraged to provide feedback through an audibility survey at arcg.is/0SPjfP and view an interactive siren map at bit.ly/3CgyhHJ. Ochs noted that community input is essential for improving the system. Sirens in Teton County are used for all hazards, including hazardous materials incidents, severe weather, or wildfire evacuations, alerting those outdoors to seek information from sources like NOAA Weather Radio, Teton_WY Alerts, tcincident.org, or local media. A siren wail lasting three minutes or longer indicates a real emergency. More details on the warning system are available at tetoncountywy.gov/492/Public-Warning-System.
