Hamilton County Siren System Upgrade to Begin July 20th

In an effort to enhance the county’s outdoor warning siren system, Hamilton County Emergency Management & Homeland Security (EMHSA) will be upgrading the system starting on July 20, 2020. This work is estimated to last three weeks depending on weather and any technical issues.

During the siren upgrade process, you may hear occasional and brief siren soundings in your area. EMHSA will monitor the weather on days when siren upgrade work will be done and will avoid activating the sirens during severe weather. For more information about the Hamilton County Outdoor Warning Siren System, please visit: http://www.hamiltoncountyohioema.org/warning-siren-system/.

It is important for members of the public to remember that these are outdoor warning devices and are not meant to be heard indoors. Hamilton County residents must have multiple ways to be notified of severe weather alerts.
