LIBERTY, Mo. -- When the weather turns bad in Liberty, the blast of public warning sirens are there to help warn people. City officials confirm that on Sunday night, those sirens didn't sound.
Liberty city officials say it was no accident that the city's storm sirens remained silent. Those sirens are triggered by a radio signal, and despite a recent test, those signals weren't in use.
Sirens like this one off Highway H aren't typically quiet during stormy weather.
"The sound is intended to provide outdoor warning," Liberty Fire Chief Mike Snider said.
Chief Snider manages the city's fire brigade, as well as public emergency services during weather events. He says the sirens are controlled via radio frequency from a centralized location. The city tested the related radio equipment last week, when some intermittent signals were discovered.
"We felt they would function," Snider said. "We just had a high-enough level of concern that we wanted to inform the public."
That's when city officials sent out precautionary reminders via email and social media, advising the public that sirens might not go off. Chief Snider says the gear was tested again on Sunday, but the sirens weren't used.
"We believe they're active now, as we did yesterday during the event," Snider said. "We just had those causes of concern and we wanted to take that proactive approach."
The scream of the sirens mean a lot to Fred Langner and his tennis pals.
He's on the outdoor courts at Liberty's Bennett Park five days a week, with a storm siren about 200 yards away. On Sunday evening, he was at a graduation party when the storm moved in.
"The first thing I said when it passed was, 'I didn't hear any sirens'," Langner said. "The fact that it was brought up in our group, I'm sure it did for everybody else too."
Chief Snider tells us the siren system will get a precautionary test later this week, once the current storm system passes. He also says those sirens are tested on the first Wednesday of each month. He says the sirens -- and radio transmission -- worked fine during the most recent test, which was two weeks ago.
He's confident they're ready to go for the next time they're needed.
