Hamilton County Emergency Management has adopted a revised policy concerning use of outdoor emergency sirens to notify residents of severe weather. Effective Aug. 1, outdoor sirens in Hamilton County will be activated under one of four conditions:
1. If the NWS issues a tornado warning for all or part of the county, outdoor sirens will be activated for that part of the county under the warning.
2. If a funnel cloud or tornado is identified by trained public safety personnel.
3. At the discretion of the Emergency Operations Center staff or, based on storm spotter reports, in the event of a straight line wind event causing damage.
4. At the request of a municipal official such as a mayor, police chief or fire chief.
Activation of the outdoor sirens during for any of these reasons will be done on a 5 minute on, 5 minute off rotation for the duration of the emergency. Outdoor sirens are owned and maintained by local municipalities so if one part of a municipality is under siren activation then all outdoor sirens in that county will be activated.
Testing of outdoor emergency sirens in Hamilton County will continue at 11 a.m. Fridays unless the temperature is below 32 degrees or in the event of potential bad weather.
