A state-by-state look at effects of Oct. snowstorm

A state-by-state look at some of the effects of the late October storm that shocked the Northeast over the weekend with up to 30 inches of snow. The wet, heavy snow accumulated on still-leafy trees and snapped off branches or toppled them altogether, taking down power lines. Fewer than 2 million people were still without power Monday, and at least 21 deaths, including one in Canada, are blamed on the storm through traffic accidents, electrocutions or other causes.

Passengers stranded for seven hours or more on tarmac at Hartford's airport after being diverted from New York-area airports. At least two deaths.
