Outdoor Warning Siren System

Canton has 16 outdoor warning sirens throughout the community.  The sirens are activated for any one of the following reasons:

  • A public safety event that warrants an immediate notification to the outdoor public
  • Severe winds of 70 mph or more
  • Tornado warning issued by the National Weather Service
In the event the sirens are activated residents should seek shelter immediately, and tune into WJR am radio 760, or local television networks such as Fox, WDIV, or WXYZ.  

Because outdoor warning sirens are designed to warn people who are outdoors, it is recommended that residents purchase a NOAA weather radio with Specific Area Message Encoding (SAME) to alert them of severe weather and other hazardous incidents when indoors and not near a regular radio or television.  For more information on these radios visit the National Weather Service.

Monthly Siren Testing
Canton's outdoor warning siren system is tested on the first Saturday of the month at 1 p.m., with a one-minute steady tone.  (Sirens are not tested during the months of December, January or February.)
