The monthly outdoor warning siren test for communities in Ottawa County will be conducted on the first Friday of every month at 12:00 p.m., April through October.

Outdoor warning sirens represent only one part of a broader public emergency notification system.  Other components include:  National Oceanic and Atmospheric Administration (NOAA) All-Hazards Weather Radio, law enforcement, emergency management, text notification networks, private sector meteorologists and the media.

Outdoor Warning Sirens are used to alert citizens of an imminent hazard, and prompt them to find shelter and seek further information.
