A small [tornado has damaged houses in Oberrad](http://www.fr-online.de/frankfurt_und_hessen/lokalnachrichten/frankfurt/?em_cnt=1161076), a suburb of Frankfurt (Article is in German). Oberrad is about 15 minutes by tram from where I live. The event lasted all of ten seconds, but damaged about 30 roofs and knocked down 15 trees. Overall I have to say the weather is really freaky this year – brooding heat is followed by bad thunderstorms, and this week we’re supposed to only get 15°C – not that I am complaining, I do not enjoy to sweat, but it’s definitely unusual.
