Oklahoma City’s outdoor warning sirens repaired, routine audible test at noon Saturday

Post Date:05/31/2019 1:30 PM

All of Oklahoma City’s 182 outdoor warning sirens should be working normally after officials repaired 18 sirens likely damaged in recent storms.

Unless there’s a threat of severe weather, the sirens will be audibly tested at noon Saturday as normal. Anyone who can usually hear a siren during a test, but doesn’t hear a siren during Saturday’s test, should call (405) 231-2121 to report it.

The City will announce on its Twitter account (@cityofokc) Saturday morning if the test is canceled for weather or another reason.

About outdoor warning sirens

In Oklahoma City, outdoor warning sirens sound when the National Weather Service (NWS) issues a tornado warning.

Although the sirens can often be heard indoors, their primary purpose is to alert people who are outdoors that a tornado threat is nearby. Even if you normally can hear a siren inside your home, you may not during a noisy thunderstorm.

You should have at least three ways to get tornado warnings:

  • If you’re indoors, the best primary source is an NOAA all-hazards weather radio, which activates when it receives a radio signal from the NWS. You can put the radio near your bed to wake you up if you’re asleep, and there’s adaptive technology available for people with vision or hearing impairments.
  • Backup options for your secondary source include:
  • Outdoor warning sirens should be a third source of information after an NOAA all-hazards weather radio and a backup source.
  • Residents with visual or hearing impairments should use Oklahoma City’s Accessible Hazard Alert System to receive tornado warnings. You can sign up at for free alerts in American Sign Language and English voice and text.

If you hear a tornado siren or get an alert about a tornado warning in your area, immediately take shelter and get more information about the weather.

About the siren repairs

Sirens are tested silently every weekday, and audibly every Saturday at noon if there’s no severe weather threat.

The silent test Tuesday, the first after the Memorial Day holiday weekend and recent severe storms, revealed 18 sirens may not have been working properly:

The sirens have since been repaired and should operate normally during Saturday’s test, and in an emergency if needed.
