CLAYTON, Mo. (KMOV.com) – A tornado siren test Monday morning yielded some concerns after none of the sirens alarmed. But the director of the emergency communications commission Duff Barney tweeted earlier saying some sirens did not alarm due to construction activity.
St. Louis County recently installed a large metal ladder that linked the roof of the county administration building to a section of that building that projects out from the room. That protruding section houses antennae’s including the one used for tornado sirens. According to the emergency communications commission, the ladder blocked the radio signal from the dispatch center, thus not allowing the siren to sound.
A spokesperson for the county said the antennae will be raised later on Monday.
There is a backup location in Chesterfield to dispatch the siren manually. Barney said they will find a way to use that Chesterfield location remotely.
