Blizzard

"Blizzard" is a disaster in the game.

Symptoms
Storm Clouds will cover the sky and after the popup message white coloured rain will fall and freze buildings by turning peices white.

What to do
You will have to get inside a building which will stop you from slowly dying by cold. Then whenever a peice turns white move away from it. A good idea is to stand in the corner of a building as if the walls fall down it will still cover you and also protect you from other falling peices.
