Every inch of rain roughly translates into 10 inches of snow.

After reviewing the weather patterns of the past recorded years, I can assume that a snow storm on the magnitude we have not seen in the United States is bound to happen in a short time. Likely 30-40 feet, possibly more over the course of a winter on the Eastern Seaboard of the US.

Houses crushed under the weight of 30 feet of snow would be everywhere.
Buildings we rely on to provide shelter would also be crushed because they were not built to withstand such pressure.
Communications, electricity, fuel delivery would cease because roads would become impassible.
Since the snow would most likely occur early in the season other snow would compact the problem as the season progresses.
Those who were not crushed would be suffocated as snow does not permit air to reach what it covers.

Anyone care to comment?

I had just read that the closest galaxy to ours is 1.6 million light years away and that there are something like 200 billions galaxies. Is this correct information? Also, about how many stars are there in the universe? Given the age of the universe, how did matter reach such distances traveling slower than the speed of light? What's the fastest speed the furthest galaxy had to travel to reach it's current point in space?
