Integrated Public Alert and Warning System (IPAWS)


As of February of 2023, Macomb County now participates in the Integrated Public Alert and Warning System (IPAWS).

IPAWS allows Macomb County officials to send life safety messages to residents via several pathways:

  • Emergency Alert System (EAS): Television and radio alerts that are broadcast to all of Southeast Michigan.
  • Wireless Emergency Alerts (WEA): Emergency messages sent via advanced cellular technology. WEA messages are 90 or 360 character messages received by all capable cellular devices in the warned area. All modern cellular devices are enabled to receive WEA alerts out of the box, although users can opt out in their phone settings.
  • NOAA Weather Radio

Macomb County intends to send WEA messages in the event of any life safety incident impacting the county, including dangerous weather, hazardous materials incidents, and other natural and man-made disasters.

WEA will be used as a complement to our Outdoor Warning Siren system; whenever Macomb County activates its sirens, cellular devices in Macomb County will receive a WEA as well, either from the National Weather Service or Macomb County Government itself.
