The "All Clear" signal is given over FM radio and NOT the storm sirens. Try to remain calm at all times.
If local radio is available, keep tuned to KOSU-FM (91.7 MHz), KSPI-FM (93.7 MHz), KVRO-FM (98.1 MHz) or KGFY-FM (105.5 MHz) for storm details. The Stillwater Emergency Communications Center can interrupt the audio of these radio stations to broadcast warnings. They can also interrupt the audio of most cable (not satellite) TV channels.
