Case Study: Perry County, MO achieves timely, targeted tornado warnings and reduced casualties with Everbridge Nixle

Perry County, MO - Customer Case Study

Everbridge Nixle worked with Perry County, Missouri — a rural community of about 20,000 that is frequently hit by tornadoes — to address gaps in warning coverage. County sirens couldn’t reach all residents or convey location and severity; when an EF4 tornado struck in February it caused widespread damage and destroyed homes of more than 60 families.

By integrating Nixle with the National Weather Service, Perry County automatically pushed NWS-issued tornado warnings to residents in the storm’s path, providing timely, location-specific alerts. The warnings helped residents take shelter, limiting human impact to mostly minor injuries and one fatality, and post-storm advisories (shelters, road hazards, assistance) led to nearly double the number of Nixle subscribers.
