When rain cats an dogs!

I'm living in the east zone of Spain, near to mediterranean sea, I had lived at country for eighteen years.

I have learn many things living here, the soft weather all the year, summer near the beach, soft winter... But twice arrive the cool drop, its a kind of heavy rain, and the to rivers above my home fill up and I can't go out of my home, or worse, I cant came in if that happens when I'm out...
For example a week ago... I ended my work day and drive to my home... But I encountered that nice and sad pic...
