I think the picture says it all. This wasn't strong wind, it was one freak 'mini-tornado' (as the DET will no doubt label it) of wind that just batterd Derby town centre.
Andy R and I were in the Eagle Centre Market and a big chunk of roof lifted off and slid down the outside of the building (with a noise remarkably like that cloud of black smoke monster in Lost).
When we got back from lunch the 2 Jags that have the best parking space in the carpark had a tree on them and there was crap everywhere.
God hates Derby and Jag drivers. Who can blame him.
Update: Nothing 'mini' about it, the Derby Evening Telegraph claims full tornado status (10:36 - 15 Sept '06) :-)
