Sirens are designed to alert those who are outdoors of an imminent hazard, most often severe weather, prompting them to find shelter and seek further information. Sirens can typically be heard (outdoors) about a mile from their sounding location. More at details are available at https://www.miottawa.org/Sheriff/sirens.htm. Sirens will continue to be tested on the first Friday of each month through November.
The tests are good reminders for residents to prepare for severe weather by having emergency supplies in their homes, such as water, flashlights, non-perishable foods and other items. Learn more about building a kit at www.ready.gov/build-a-kit.
Outdoor warning sirens represent only one part of a broader public emergency notification system. Other components include National Oceanic and Atmospheric Administration All-Hazards Weather Radio, law enforcement, emergency management, text notification networks, private sector meteorologists and the media. Smartphone apps can also provide notification of weather watches and warnings.
