A thunderstorm, seen from the relative safety of the subway stop in Garching.
Ok, it is really summer now. After some hot days, today southern Germany was hit by massive thunderstorms. Luckily I saw it coming, right after a colloquium talk at the MPI for Physics, so I made it in time to the subway. However, once I got home to Garching, things were really bad: Several inches of water on the streets, rain pouring down, lightning and thunder everywhere. So here I was, trapped in the subway station, waiting for things to get better. Well, at least I tried to take a picture with my mobile phone. Admittedly, it does not look quite as bad as it felt right then and there, but now, dry again, I’m really looking forward to summer.
Not just southern Germany was hit, we too had short but strong (and sudden!) showers in Hamburg this afternoon. Still, not as unpleasant (not exactly inches of water) as you describe it, so I guess we were lucky.
