Occasionally our outdoor warning sirens need to be worked on or tested outside of the "normal" Tuesday 9 a.m. weekly test. At those times, we do our best to coordinate with the maintenance workers to alert those in the area of that siren.
Tomorrow, Marshalltown will be working on a single siren.
Scheduled testing of the outdoor warning siren on E. State and N. 12th Ave. is 8:00 AM tomorrow, Thursday September 3rd.
AND
Currently, Haverhill's siren is not functioning and they are working to remedy the electrical problem.
We will keep you updated on both of these sirens as we receive more information.
* Note: Emergency Management does not own the outdoor warning sirens in cities or the county. These are owned by the jurisdiction the siren is in and the responsibility of those jurisdictions to maintain. Emergency Management helps coordinate maintenance schedules, tests via computer/radio communications daily, alert or test remotely as needed for backup/redundancy, and works to add more sirens in the county/cities by securing grants when possible. 911 (communications center) is responsible as the primary siren activation point on Tuesday testing and during tornado warnings.
