Denver is making changes to its emergency notification system after the city’s sirens were mistakenly sounded during a hail storm earlier this month. The city will now rely on the National Weather Service to decide when conditions are severe enough to trigger the sirens.
The National Weather Service already issues wireless emergency alerts for most weather-related emergencies, which are sent to phones in a specific area. The city’s sirens will not be sounded for weather emergencies until the National Weather Service issues one of these alerts first.
The city will also issue fewer emergency alerts for non-weather emergencies, such as an active shooter or other major threats. Instead, the public safety department will prioritize using reverse emergency notifications, which include voice calls, texts, or emails to residents who have opted into the service.
