Chicago's Tornado Sirens Will Haunt Your Dreams

Braindrops - Creepy tornado alert

Check out this video of a tornado warning siren going off in Chicago. 

(Crank the sound all the way up for extra creep factor)

I did some research into these very..unusual...sirens and found they were part of a "SiraTone" line designed back in 1981. The concept was to allow different tones/patterns for different events. Also, there was some thought these sirens would be so distinct, they couldn't be confused with any "normal" city noise.

There's an understatement.
