City of Irving Outdoor Warning Sirens & Lightning Detectors

This system is meant to warn residents who are outside only. You may not be able to hear it inside or in noisy areas. To receive emergency notifications indoors, the Office of Emergency Management recommends the NOAA (National Oceanic and Atmospheric Administration) All Hazards and Weather Alert Radio with the Specific Area Message Encoding feature. The NOAA radio allows you to keep up to date on all types of emergencies 24 hours a day. You can buy one at many local retailers starting at $20.


When activated, the Outdoor Warning sirens will rotate 360 degrees while sounding a steady tone for three minutes. It may be continuously sounded until the danger has passed. There is no all-clear message. When you hear the Outdoor Warning System sound, you should immediately go inside and tune into the local news for additional information.
