Unusual mammatus cloud formation delights Berlin residents as it passes over city

Berlin residents caught a glimpse of the unusual mammatus cloud formation as it passed over the city on March 11. Timelapse footage filmed by Jörg Lorenz shows the unique formation which looks as if there are pouches hanging underneath the base of the cloud. Lorenz said in a Twitter post: "Actually, I had set up the cam for a rainbow. That came too. But things got better after that."
