Following is a state-by-state look at the effects, as of early Monday, of the deadly, late October storm that shocked the Northeast on Saturday and Sunday with up to 30 inches of snow in spots.
The wet, heavy snow accumulated on still-leafy trees and snapped off branches or toppled them altogether, taking down power lines.
Communications were disrupted by collapsed cellphone towers. More than 3 million people lost power at some point, and at least a dozen deaths are blamed on the storm through traffic accidents, electrocutions or other causes.
CONNECTICUT: More than 750,000 customers still without power, down from more than 830,000, a number that broke the record set by the remnants of Hurricane Irene in August. At least two deaths. Passengers stranded for seven hours or more on tarmac at Hartford's airport after being diverted from New York-area airports.
MAINE: About 41,000 without power, down from about 160,000. It could be several days before power is restored.
MASSACHUSETTS: More than 500,000 without power. Delays on commuter rail into Boston. Dozens of school districts cancel classes; many communities call off Halloween trick-or-treating because of downed power lines.
MARYLAND: A few thousand without power, down from about 43,000.
NEW JERSEY: Gov. Chris Christie says damage to utilities in the state is worse than that wrought by Irene. More than 400,000 without power, down from more than 612,000. Some rail lines still blocked by fallen branches, snarling the Monday morning commute for many people who live in suburban New York and work in the city.
NEW HAMPSHIRE: About 187,000 without power, down from more than 315,000. Seven shelters open for people without heat.
NEW YORK: More than 270,000 without power, down from more than 300,000. Dozens of motorists stranded up to 10 hours on snow-covered highways north of New York City.
PENNSYLVANIA: More than 200,000 without power, down from about a half-million. At least six deaths.
RHODE ISLAND: More than 1,700 without power, down from about 20,000.
VERMONT: About 7,500 lost power at some point. Areas devastated in August by remnants of Hurricane Irene reported 13 inches.
