Minnesota's Mini tornado outbreak of 7/11/08.

Like the first video...For counties that don't use their sirens for attacks, I think they should sound the sirens in attack when there is an actuall tornado on the ground.

That second video...something odd about it.

I think that the loud, lower pitched 2001 in the second video may actually be a Thunderbolt 1000. The more I listen to it, the more I think that that's what it is. Listen to it wind up. It also doesn't quite have the same tone as the other 2001's. It's weird how it winds up at exactly the same time as that one 2001, making it sound like a second interval duel tone siren. There may even be a faint Thunderbolt 1000T in that mix as well.
