Warning Sirens
Hear a siren outside of a scheduled test? Go inside and take shelter now. Check local news or a weather radio for updates.
Sirens are tested the first Monday of every month at 11 a.m., unless inclement weather prevents testing. Sirens are operated by the St. Louis Fire Department.
What it sounds like: A loud, steady tone that holds one pitch for three minutes. It may seem to fade in and out as the siren rotates.
Didn't hear the siren during a test? Report it online or by calling the Citizens Service Bureau at 314-622-4800. Include your approximate location.
Statewide Tornado Drill: Each spring, the City also sounds the sirens for Missouri's statewide drill, unless it conflicts with a local election. Use it to practice what you'd do in a real tornado.
