Monthly Siren Test
Monthly Siren Test 
The Outdoor Warning Sirens will be tested twice today during the monthly testing session. This additional testing will confirm that both siren activation points are operational.
The first test will take place at 11:00 A.M. The second test will occur approximately at 11:15 A.M. THESE ARE ONLY TESTS.
Report siren malfunctions to the Citizens' Service Bureau (CSB) at (314) 622-4800. You can also comment here if you hear the siren, but we ask that you leave a nearby intersection or block and street number.
