Outdoor Warning Sirens

The City of Fort Worth Outdoor Warning System may be activated for any kind of emergency – not just severe weather.

The Fort Worth outdoor warning system consists of 153 sirens strategically located throughout the city. Sirens are designed to serve as a warning for people outside of their business or residence. If you hear the sirens sound, seek sturdy shelter immediately. Make your way to an interior room, away from windows and exterior walls, and turn on a radio or television to a local station for more information.
