I'm still calling shenanigans on that picture of the snow busting through the doors. Plenty of physics people here... what do the rest of you think? I believe that mother nature had the help of a lot of human intervention. If you search, you can find tons of pictures of people who opened their doors, and the snow doesn't tumble in - it just stays there. It doesn't behave like a fluid exerting much of a horizontal force at all. If you have a 6 foot snow drift over your sidewalk, you can cut straight down through it, making a vertical wall of snow - no horizontal forces. And, certainly not enough horizontal forces to smash a door off its hinges and tumble 7 or 8 feet into a room with a depth of barely over 4 feet. Search Google - find another image of someone's door or window being smashed open. You can find endless images of snow up over windows - snow deeper than doors (which wasn't the case for that door - they took pictures just before and after).
Methinks the motivation was to get 15 minutes of fame.
