A tornado has struck Kensal Green in North West London. Up to 150 houses have been damaged, and six people were injured, one seriously. Residential roads were closed off, but most have now been re-opened. Residents have had to seek temporary accommodation. Traffic was also diverted causing disruption but has now returned to normal. The cost of the damage is estimated to be at least £20,000,000.
