This is a huge storm.

Frigid air coming south from Canada also is expected to get ingested into Sandy, which will only help to strengthen the storm further and create winter storm conditions for some in the storm’s path.

Officials are bracing for the worst: nearly a foot of rain, high winds and up to 2 feet of snow in the highest parts of the Appalachian Mountains from West Virginia to North Carolina.

I have never forgotten the day that I saw what Katrina looked like from space.  The size of the storm is what is so ominous.
