Tulsa County, Oklahoma. Emergency Sirens
What do sirens tell you?
Being prepared when disaster strikes can help save lives and property, prevent injury and decrease recovery costs.
Knowing what the City's warning sirens are telling you is part of being prepared for emergencies. Understanding the three siren tones can help you take the right action to protect yourself and those around you.
There are more than 80 in the city, each audible for up to a mile.
Tulsa's sirens use tones that warn citizens about tornadoes, military attacks and about chemical releases into the atmosphere.
There is an additional warning that is unique to this community. It is a flood warning tone which is not a part of the federal guidelines for siren warning systems.

~ Second is the three-minute "wavering" tone - similar to the "wailing" sound made by many police and fire vehicles on emergency missions. That tone is used only to warn of nuclear attacks.

Sirens are only a part of Tulsa's warning systems and are intended to warn people who are out of doors about impending dangers.
The warning system also includes local news media, NOAA Weather Radios and even some local wireless phone and pager services.

Testing
Tulsa's warning sirens are audibly tested each Wednesday at noon, weather permitting, as well as being silently tested daily. On occasion, technicians may test individual sirens at random times. Tests are typically one minute in length. Actual warnings are three-minute signals.
