We often call them leaches or trumpets like elephant trunks which descend from lower parts of the clouds to the ground but we can all agree in one thing, tornados are simply Terrifying.

Tornados suck everything that comes before them and carry it to the sky. They can suddenly change direction of even return to the same path they were,

The most affected city in the United States is Oklahoma City, who was a victim of the tornado over 100 times.

Below you can find a video of a creepy sound produced by Tornado Sirens in Chicago! It is not clear however is this a real siren or just some wind blowing into tubes. Share this creepy video with your family and friends on facebook.
