Tornado vid, with xT22 siren

[danwisbey85]

Found it on youtube, old tornado back in 91 in Kansas, has a xT22 siren sounding the alert for tornado warning.
The siren cuts off as the tornado knocks out the power. (You do here it cut down briefly)

The 1991 Andover, KS tornado is one of the most know, mostly due to it's sheer destruction (I believe it was an F4) by tearing through the heart of the city. That is a great video though. The combination of the 2t22 and the tornado is a heck of site. Man that is scary.

That was part of a show on the History Channel called "Twister, Fury on the Plains"

Yipes! That is scary! either these guys are professionals or very brave and crazy o__o

I saw that twister smoke a power line or a transformer (the cylinder things at the top of the pole) that's always freaky to me o_o

How do Air Raid sirens survive all this?? 0_0

Tornadoes aren't very wide, most sirens get missed.

Nice vid, a little stupid to be standing out there though. All it takes is a piece of flying sheetmetal, and bye-bye head.

That isn't always true. Some like an F5 can be over a mile wide

[SirenMadness]

Yeah, I know, but even with that width, not all the sirens, or other values, in a community will be affected, depending on the course.

Yes but with an F5, virtually nothing is left standing when it disappears.

Alright, to put the myths to rest. Tornadoes can be large or small, regardless of their intensity. You can have a fairly wide tornado, yet only have it be an F1 or F2. Yet, you can have a very small tornado and have it have an F5 rating.

Now, with a siren sytem being affected, it depends exactly what kind of system is present. If it is one of the older "Cold War" era systems, they are more likely to be affected for two reasons. One, most of the sirens are on wooden polls which do not hold up well in extremely high wind speeds (and with flying debris). Two, most of the sirens do not have battery backup. So if a main line or a sector gets cut off and put out of commision, the sirens could be down for a number of days. However, if the siren system is a newer type of system, chances are it will be only affected in a small way. The concrete spun or metal poles are very resistant and most of today's sirens are battery backup or have solar power, making them capable of working when the power is out.

Also, I don't believe that clip was from a show on The History Channel. It appears that is was broadcasted on The Learning Channel (TLC). I would highly doubt the two would share the same type of broadcasting.
