Washington - The US capital struggled to plow and shovel its way back to life Monday after a blizzard smothered the East Coast, with mountains of snow lining streets, and schools and the federal government shut down.
The storm was blamed for at least 33 deaths as it slammed a dozen states from Friday into early Sunday, many of them people who suffered heart attacks while shoveling, or killed on icy roads, though several died of carbon monoxide poisoning trying to keep warm in cars or homes.
Washington's subway and bus network, closed all weekend, resumed service Monday but on a very limited basis with trains running for free.
More accustomed to heavy snowfall, New York City seemed to bounce back more easily with schools in the Big Apple open and the mass transit system up and running for the most part.
But for many the thrill of a weekend spent playing in the snow, or in warm homes watching a stunning display of nature's power, gave way to the realisation that, in Washington at least, the cleanup will be long and messy.
"From my estimation we got more snow than I have ever seen in Washington, D.C.," Mayor Muriel Bowser told CNN. "We are working hard to dig out all of our residential streets."
Under a sunny sky, the normally bustling avenues around the White House were all but deserted.
Heavy machinery equipped with powerful vacuums sucked at chest-high drifts of snow and spat it into 18-wheel trucks moving alongside at a snail's pace.
Dump trucks laden with the stuff rumbled through the streets and crews in bright red shirts went at it with shovels. Everywhere, there was snow.
The few people out and about trudged through slush and ice and picked their way through drifts left by plows. Most restaurants, office buildings and stores remained closed.
Limited flight operations resumed Monday from Washington's Reagan National and Dulles International airports, a day after officials battled in New York to get some aircraft off the ground.
More than 22 inches (56 centimeters) of snow paralysed Washington, while the 26.8 inches (68 centimeters) that fell in New York's Central Park was the second-highest accumulation since records began in 1869.
"We now know this blizzard came within .1 inch of being the biggest snowfall in history" in New York City, Mayor Bill de Blasio said Monday morning. At one point, 2,500 snow plows were operating.
"We were getting as much as three inches in an hour. So this really was the big one," he added.
Near-record-breaking snowfall blanketed cities up and down the East Coast, with Philadelphia and Baltimore also on the receiving end of some of the worst that Mother Nature could fling at them.
Fatalities occurred in Arkansas, Delaware, the District of Columbia, Kentucky, Maryland, New York, New Jersey, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee and Virginia.
In Passaic, New Jersey, a 23-year-old and her one-year-old son died of carbon monoxide poisoning during the storm, while the family's three-year-old daughter was hospitalised in critical condition.
"The father was shoveling their car out and the wife and kids wanted to stay inside the car to keep warm," Detective Andrew White told AFP. "The car's exhaust pipe was covered and blocked with snowing causing carbon monoxide to enter the car."
Some 85 million residents in the storm's path were told to stay indoors for their own safety, and hundreds of thousands were left without power, including nearly 150,000 outages in North Carolina alone, emergency officials said.
Beyond New York and Washington, New Jersey, Pennsylvania, Maryland and Virginia were the hardest-hit areas. A few locations surpassed one-day and two-day snow records, said the National Weather Service.
As the storm ended and temperatures rose, New York emerged from total shutdown and lifted a sweeping travel ban on Sunday.
Broadway resumed shows and museums reopened, as snow plows quickly cleared the main avenues and temperatures hovered at about 32 degrees Fahrenheit (zero Celsius).
Thousands of people flocked to parks, tobogganing, organising snowball fights and strapping on cross-country skis, as children delighted in a winter wonderland under glorious sunshine.
But in Washington residents were bracing for the disruption to drag on for days, with the House of Representatives opting to remain out of session for the coming week due to the severity of the winter storm -- with no votes set until February 1.
Much of the subway system's above-ground stretches remained closed.
"We're not going to wait to reopen the whole above-ground system in one fell swoop," Metro spokesman Dan Stessel said. "We'll open segments of the lines as soon as we're able."
