I must admit that I often associate tornadoes with America and the Tornado Alley regions. I think it's because for some reason the media never seems to really report on tornadoes over here, usually relegating them to side mentions in between more "important" news articles.

We're always having freak storms :D I sort of remember one from when I was a kid in the late 80's where the BBC weathermen said a gale was on the way but many people believed afterwards it was more like a mild hurricane. I think most of the south of the country was effected in some way, I know the next day all our garden fences had been knocked flat and my dad was a bit annoyed about it. :)
