By KMOV Web Producer
(KMOV.com) -- Workers had planned to test the new tornado siren system is St. Louis County on Wednesday, but weather conditions forced officials to cancel.
The tests were scheduled to happen between 10 a.m. and 2 p.m. Now, the tests will be rescheduled for next week, February 1st.
Before the sirens are activated, a "This is only a test" announcement will be broacast from the particular device about to be tested.
In an actual emergency, the sirens would wail continuously for three minutes. Their activation serves as an alert that a tornado or tornadoes are approaching the region and that residents need to immediately take cover.
The exception to this is the first Monday of every month, at 11 a.m., at which date and time the sirens are tested regularly.
