    ​​​​​Outdoor Warning Sirens​

    The Outdoor Warning System (OWS) consists of 168 sirens strategically placed throughout the City of Dallas. OEM constantly monitors the system for functionality and coverage. The OWS system is tested on the first Wednesday of every month at 12:00 noon, weather permitting.

    The Outdoor Warning System is not meant to be heard indoors. The OWS system is designed to alert anyone outside that they need to get inside. Once inside and safe, turn on your NOAA weather radio, TV, radio, or other news source for more information and instructions.
