Ice! It had been raining nonstop for days (quite warm weather). Then all of a sudden it froze while raining (didn't convert to snow). Ice developed everywhere and engulfed everything. These are portions of trees. During the night, every 20 or so minutes, I would hear a loud noise. The next morning, I saw that the branches had snapped right off the trees because of the ice. The next day my car was totally covered with ice. I managed to chip enough to insert my key and even unlocked the car. But the door simply wouldn't open. It would have been pointless, as the windows and windshield were covered with such a thick and smooth layer of ice that there would be no way I would be able to scrape it off. I tried for half an hour, anyway.
