Emergency Weather Warning Sirens

Monthly tests of the emergency weather warning sirens are conducted by St. Charles County Emergency Management on the 1st Monday of every month at 9 am.

How do I report a malfunctioning weather warning siren?

If you notice that a weather warning siren is not functioning, contact Emergency Management Director, Cpt. Kevin Pyatt of the Wentzville Police Department at 636-639-2102 and advise the location of the siren.
