I think the big story here is that there are English people on Lewis!!
I wonder if the BBC crew tried interviewing the locals but couldn't understand them and counter their lucky stars when a familiar accent asked "wots all this then?"
Yeah, UK does supposedly get a lot of tornadoes... although maybe they: don't make it to the ground, don't last very long and don't have a lot of oomf.
Having said that, never have I seen one... but I've only seen fork-lightning once...
Maybe there just aren't suitable quarries nearby to build their houses?
It is a bit of a wonder why they don't take in the unique weather (tornado!) into account when building houses. The only preparation they have is a storm shelter underground and when it clears they come to find their houses in ruins.
Ironically, the houses here would barely be dented by a tornado... fair enough a flying car is going to be hard to stop, but the winds themselves aren't going to bother granite much
Caveats apply as it is entirely possible that the information contained in the above post is either an attempt at a wind-up, an attempt at a joke or just plain wrong.
