The outdoor warning system consists of 162 sirens strategically placed throughout the City of Dallas.
Outdoor warning sirens are designed to alert people outside to go indoors for shelter and information. The sirens are not meant to be heard indoors. Once in a safe location, tune to local media for up to date instructions.
The sirens are tested on the first Wednesday of every month at 12:00 noon, weather permitting. Let us know how the system is performing by taking this short survey.
