CNN) -- A major winter storm walloped the Northeast on Friday, a day after heavy snow closed schools and roads and caused dangerous conditions.

The storm prompted authorities to cancel flights in New York and Philadelphia, Pennsylvania, on Friday. They also suspended bus service in northern New Jersey.

At least 32,000 people were without power Friday morning -- 22,000 in New York and 10,000 in New Jersey, Con Edison and emergency officials said.

Forecasters said parts of New York state could get up to a foot of snow, and public schools were closed Friday in New York City.

"The heavy, wet snow will be sufficient to bring down trees and power lines and could also cause roof collapses," the National Weather Service said.

The storm is the third to hit the region this month.

Early Friday, American Airlines had canceled 42 flights out of New York, a spokeswoman said. Delta Air Lines canceled 300 flights from airports in New York and Philadelphia, and airport authorities expected more cancellations throughout the day.

The storm prompted the cancellation of more than 1,000 flights at New York-area airports Thursday, said John Kelly, a spokesman for the Port Authority of New York and New Jersey.

Parts of New York had received from 22 to 30 inches of snow by Thursday evening, the weather service said. Massachusetts was averaging 22 inches across the state. Parts of Pennsylvania had as much as 12 inches. Areas in Vermont received as much as 38 inches of snow.

A snow-covered tree limb fell Thursday in New York's Central Park and killed a 46-year-old man. The New York City Department of Parks and Recreation warned residents to stay out of city parks after the death.

For some, any more snow was just too much.

"I've just been shoveling," a weary man told CNN affiliate WBRE-TV in Wilkes-Barre, Pennsylvania. "And it looks like I'll be doing some more shoveling."
