The Town of Johnstown has a scheduled tornado siren TEST for Thursday, June 24 at 1pm for all neighborhood sirens, weather permitting.


Testing Results - 6/24/2021

Johnstown, CO - June 24, 2021 - Testing Results: The Town had Public Works and Police Department personnel at every siren to confirm functionality. The CLEARVIEW SIREN did not go off, which alerted us to a mechanical problem and an electrician immediately assessed the issue. The mechanical part that the CLEARVIEW SIREN needs for functionality to return, has been ordered and will be fitted in the coming weeks. A very brief isolated test of that siren will happen following the repair and more information with a date/time will be provided just prior to that happening. Thank you for your cooperation.

  • Stay away from windows, doors, and outside walls.
