The Village has an outdoor siren warning system that is used to alert the community about possible emergencies. In the event of possible severe weather or other emergency, the siren will sound. Please turn on your radio to WDCB 90.9 FM and/or local television, for further information. Do not dial 9-1-1 to ask why the sirens are activated.
The siren is activated when severe weather or a storm is detected at the county line or anytime a trained public safety official directs their activation. The sirens are activated by Du-Comm or the Lombard Emergency Communications Center.
The warning tone, or alert tone is three to five minutes of a steady blast. This means that there is a possible danger, for example, a tornado or severe weather approaching. This should not be confused with the siren heard on the first Tuesday of every month at 10:00 am. This is the time chosen when all warning systems are tested in the state.
There is no all clear signal. Residents and visitors need to observe the situation and collect information from other sources. If a second or third activation occurs, this indicates that there may be emergencies in the area and sheltering is recommended.
