EF5
NOTE: Weather warning is a steady siren for 3 to 5 minutes.
Attack imminent is a wailing siren for 3 to 5 minutes.
Back on September 22nd 2006 the sirens being sounded downtown were the wailing sirens instead of the steady sirens. On this day a brief tornado touched down on a university campus. There a video of it on youtube of the sirens and of the tornado.
i do not understand the difference between a "wailing" siren, and a "steady" siren...can someone please clarify this for me?
