TORNADO SIRENS

Oklahoma City's tornado sirens are in place to warn people within the city limits that weather conditions may produce a tornado.  When you hear the sirens, immediately turn on a television or radio for important information about the storm.

Oklahoma City sounds its sirens based on tornado warnings issued by the National Weather Service.  When the National Weather Service reissues the warning you may hear the sirens more than once.

Sirens sound for three minutes each time they are activated.  When the sirens stop, it is not an indication the threat of a tornado has passed.  Oklahoma City does not give an "all clear" signal.

Bring a battery operated or all-hazards weather radio or tv with you when you take cover so you can track the storm and know when the danger has passed.

Oklahoma City tests tornado sirens at noon on Saturdays when there is no threat of severe weather.
