WASHINGTON (MCT) – Sandy, the massive, multi-state storm that flooded tunnels in New York City, brought snow to the mountains of West Virginia, snarled early voting for the upcoming election and caused more than 8 million power outages, moved into Pennsylvania and western New York on Tuesday and put the entire Northeast on heightened flooding alert.

The storm has had significant impact in at least 10 states and the District of Columbia.

Early estimates of its economic impact show Sandy could cause between $5 billion and $10 billion in insured damage, although that’s only a fraction of the broader economic losses, which could range from $20 billion to $50 billion or even higher.
