Outdoor Warning Siren Information

Outdoor warning sirens are quite simply tools to warn people who are outdoors to take immediate, potentially life-saving action by finding shelter from an imminent deadly threat
  • These sirens will be activated in the event that a specific area is experiencing or will be experiencing, life-threatening weather conditions that may include such threats as:
    • Tornados,
    • Severe thunderstorms with winds 70 mph or greater,
    • Hail golf ball sized (1-inch) or larger.
  • These sirens are activated for 2 minutes, will be off for 5 minutes, come back on for 2 minutes, be off for 5 minutes, and this cycle will continue for the duration of the threat or until there is a loss of power to the siren (the exception is Danville and Mediapolis, these sirens are continuous).
  • The sirens are an OUTDOOR warning device.  They are not designed to be heard indoors!
  • When you hear the siren, take shelter immediately and tune to your local radio station and/or NOAA Weather Radio All Hazards for more information.
