Why an outdoor warning siren mix-up confused Boone County residents Wednesday

If you live in Columbia or surrounding Boone County, you are likely accustomed to the familiar tone of the outdoor warning sirens on the first Wednesday of every month. However, the routine test on Wednesday, November 4th, caught many residents off guard. Instead of the usual steady hum, the sirens emitted a fluctuating wail, sparking confusion across the community.

The Boone County Office of Emergency Management quickly confirmed there was no active threat to the public. According to Beth Kennedy, the Communications and Outreach Specialist at the Boone County office, the incident was simply the result of human error during the manual activation process.

"Our monthly siren tests are conducted by [the] Boone County Joint Communications Supervisor," Kennedy explained. "We have two different sounds. We've got one that's all-call steady and all-call wail, and normally we do all-call steady. That's the sound that people are usually hearing on the first Wednesday of the month."

Kennedy stated that a manual error occurred when the supervisor accidentally selected the "all-call wail" setting instead of the standard "all-call steady" tone.

Despite the startling noise, emergency officials stressed a silver lining: the hardware itself worked flawlessly.

"The system functioned properly. I mean all of our sirens went off without any issue," Kennedy said, noting that the public's quick realization was actually a positive sign. "Residents did hear the sound difference, which is good. That's why we test these every month is to make sure that they're still functioning regardless of what noise comes out of them, what sound comes out of them, and we do again apologize for the confusion, but there is no active threat to the public, and we are working on ways to make sure that this doesn't happen again."

While Boone County is reviewing its testing procedures, this unexpected alarm serves as a highly relevant reminder. The confusion highlights a misconception of how we should receive emergency alerts.

Outdoor warning sirens are designed for one purpose: to alert people who are outdoors during an immediate, life-threatening danger, such as a tornado. They are not engineered to penetrate the walls of a well-insulated house or an office building, or to wake you up in the middle of the night while you are sleeping.

You shouldn't rely on outdoor sirens alone as your sole source of emergency information. To keep you and your family safe, it is important to have multiple ways to receive warnings. Ensure your smartphone has Wireless Emergency Alerts enabled, keep a battery-powered NOAA Weather Radio in your home, and download the ABC 17 Stormtrack Weather App for localized, up-to-the-minute weather notifications straight to your pocket.
