Early Warning System in Chicago

Chicago has elected to apply the Modulator® II Electronic Siren Series for tornado warnings. Chicago has also chosen the most eerie of the sound options the sirens provide. This siren sounds almost as though it has already been heavily affected by the tornado and thereby strongly encourages people not to go outside but to seek shelter (as it effectively sounding as if it is the end of all times). Judge the effectiveness of this warning sound during a real tornado for yourself, or try out the various other options the Siren Series provides.
