The Outdoor Warning Sirens are meant to alert those people outdoors, if an immediate threat has entered your community.  The Macomb County Sheriff’s Office Dispatch is responsible for the activation of the outdoor warning system.  In most instances this system is used for severe weather conditions but remember that when a siren is activated to never assume that you know what the threat is.  Always seek shelter immediately and if your electricity has not been impacted, refer to your local TV or radio stations, ascertain the nature of the threat and receive instructions regarding your safety.  A battery powered radio is recommended for every household or business in the event that electricity is not available.

The system may be activated for the following Severe Weather Conditions:

Tornado Warning as issued by the National Weather Service for our area
Severe Thunderstorm Warning accompanied by winds 70 mph or greater as issued by the National Weather Service for our area
Tornado and/or Funnel cloud sightings that have been verified by a reputable source

The system may also be activated for other incidents that require immediate alerting of our population to take certain protective actions.  These events may include, but are not limited to a Hazardous Material Spill that may impact the community and require either an evacuation or in-place sheltering; or an Attack Warning for Macomb County.

The county does not activate our system for an “all clear” notification once the threat is no longer present.

The Outdoor Warning System is tested the first Saturday of each month at 1:00 pm.

The 911 system in our county and in your community should only be utilized to report an actual emergency, not to notify the dispatch center that either the sirens have been activated or to question why the sirens are activated.  There are other sources for this type of information which include your local radio and TV outlets and the National Weather Service App.

For additional information regarding Severe Weather, Sheltering, or other Emergency Preparedness information please refer to our Community Emergency Preparedness Workbook that can be hyperlinked from this site.  You may also contact our office at (586) 469-5270.
