Steady Siren Tone For 3 Minutes = Take Cover!
This sound indicates confirmation of either: 1)A Tornado Warning issued by the National Weather Service or 2) confirmed sighting of a tornado or funnel cloud within the Elk Grove Village area by a trained spotter.
The sirens are sounded primarily to alert people who are outdoors. If there is no way to find immediate shelter, lie flat, face down, in a ditch or low area, and cover your head until the tornado passes.
If you are already indoors, you may not even be able to hear the sirens. During thunderstorms, be aware of conditions outside and stay tuned to your radio or television if the weather appears to be threatening.
Go to the basement or lowest level of the building. Move to an interior room and stay away from outside walls, windows, and doors.
Avoid places with wide-span roofs such as auditoriums, gymnasiums, and cafeterias.
Have a battery-operated radio and flashlight with you as power failures often occur during severe weather.
If you hear the sirens again, it is because of an additional sighting and warning. Seek shelter again!
There will be no "All Clear" siren signal. Please do not call 9-1-1 for siren information. Emergency personnel will be busy preparing for rescue operations once it is safe to go outside.
