Stay Informed with City Outdoor Warning System


The city’s Outdoor Warning System is activated in case of emergencies, such as severe weather. The system consists of 25 strategically placed sirens that are activated for one or more of the following conditions:

• Tornado warning issued by National Weather Service
• Tornado or funnel cloud reported by a reliable source
• Sustained winds in excess of 70 miles per hour
• Reports of hail larger than 1.25 inches in diameter

It is a common misconception that the Outdoor Warning System is designed to notify people who are indoors of hazards. To stay informed while indoors, it is best to purchase a National Oceanic and Atmospheric Administration (NOAA) radio.

“We recommend hazard alert radios, which will activate much like a siren inside of your home when warnings are issued,” said Emergency Management Planner Billy Owens. “These radios act as an indoor warning system, and will activate at any time of the day.”

NOAA radios can be programmed to provide location-specific emergency information. The codes for Dallas and surrounding counties are as follows:
• Dallas County: 048113
• Denton County: 048121
• Tarrant County: 048439

The Outdoor Warning System is tested at 1 p.m. on the first Wednesday of each month, unless conditions are favorable for severe weather. To see a map of Outdoor Warning System, visit cityofirving.org/oem. For more information, call (972) 721-2100.
