We operate numerous outdoor warning sirens across city limits and on the Oklahoma State University campus. Each siren is positioned roughly one-half mile from another. These sirens will activate if there is a threat of a tornado entering the Stillwater area. The sirens are in place to warn people who are outside of buildings and are not meant to be heard indoors.
When sirens are activated:
There will be a steady tone for 3 minutes, followed by an announcement describing the situation at hand.
There will not be an all-clear siren because it can create confusion.
These sirens are tested on the first Tuesday of each month at 11:30 am (weather permitting). If unable to test on the day of scheduled testing, it will be rescheduled for the following Thursday or the next Tuesday.
If you are outside and you don't hear the siren in your area, call (405) 372-7484 to report it.
