The City's outdoor weather warning system has 14 sirens that alert people who are outdoors to seek shelter in the event of a tornado. The system is tested as needed and advertised at Noon weather permitting. We do not test the sirens if the weather is bad or threatening; this helps to ensure that there will be no confusion as to whether it is a test or a real alert.
The main purpose of the sirens is to warn individuals that are outdoors to seek immediate shelter. Since many outdoor sounds, including the weather sirens, cannot penetrate many buildings, the sirens are not intended to be heard while indoors.
