I found this video yesterday afternoon. At first I thought it was another bad attempt at playing a synthesized TBolt siren over a storm video but after playing it for a while and looking up the sirens in Bemidji, MN, I believe these are indeed the real thing. http://www.youtube.com/watch?v=rESVZiD6zKA

At the time the tornado struck, Joplin had a system of mostly 2001s and an RSH10 or two lingering. One is at a MSSU and was captured winding down from the first warning cycle in this video... http://www.youtube.com/watch?v=DjMnvmja5BA The other was located directly across the street from where the f...

I think some of the concern may be that with an ATI activation and control platform, Dane County may be more inclined to install ATI warning devices.
