WASHINGTON?(UPDATE) Snow blanketed much of the eastern United States Sunday during one of its worst storms in decades with stores closed, flights grounded and traffic brought to a standstill, as holiday shopping suffered a cold snap.
In the bull's eye of the deadly weather, Washington? a city more used to political storms than deep snow drifts? shattered a 1932 December snowfall record, with 16 inches (40 centimeters) covering streets and homes.
And with more snow forecast to fall on Washington by dawn Sunday, the massive snowstorm stretching some 500 miles (800 kilometers) across a dozen states is set to become one of the biggest to sock the capital since record keeping began in 1885.
Washington Mayor Adrian Fenty declared a snow emergency, as most mass transit shut down, but expressed confidence the mostly empty city streets would be cleaned up by Monday.
President Barack Obama, attending a heated UN summit in Copenhagen where world leaders struggled over a plan to battle global warming, raced home to avoid the worst of the storm that hammered the East Coast with more than two feet (61 cm) of snow in some places?two days before winter's official arrival.
After snowplows cleared the runway at Andrews Air Force Base outside Washington for the presidential jet, Obama stepped off Air Force One into a heavy snowfall before dawn Saturday. In a rare move, he was whisked to the White House by motorcade rather than his Marine One helicopter due to the treacherous weather.
By Saturday afternoon, the capital region's three main airports? Reagan National, Washington Dulles International, and Baltimore Washington International? cancelled all incoming and outgoing flights, stranding thousands of passengers.
Crews were busy clearing runways overnight in a bid to reopen the airfields by 6:00 am Sunday.
It was bleak news for millions hoping to hit the roads and skies ahead of Christmas on one of the busiest travel weekends of the year.
With many residents forced to stay home and shopping malls shuttered or closing early, the winter wallop was also likely to take a bite out of retail sales on "Super Saturday," a major shopping day on the last weekend before Christmas.
New York Mayor Michael Bloomberg tried to put an uplifting spin on vicious Mother Nature. "Cold weather is here," Bloomberg was quoted by local media as saying. "Hopefully, we'll have a little bit of a white Christmas."
The storm turned much of the East Coast, home to tens of millions of Americans, into a winter wonderland, but the conditions were as perilous as they were scenic, authorities warned.
Three people died on roads in Virginia Saturday, according to the state's department of emergency management (VDEM), with spokesman Bob Spieldenner saying some 3,000 accidents shut down Virginia interstates for several hours. The Virginia Department of Health confirmed one other storm-related death.
Emergency services delivered heater meals and 400 bottles of water for stranded motorists, while others were moved to shelters.
"This is a very serious storm," said Maryland Emergency Management chief Richard Muth, warning people not to drive unless in an emergency.
The monster weather system was moving steadily northward, blanketing cities like Baltimore with roughly 20 inches (51 cm), Philadelphia (16 inches), and New York, where the National Weather Service (NWS) forecast near-blizzard conditions and as much as 16 inches of accumulation by later Sunday.
Boston, further north, was facing a similar fate, with blizzard warnings in effect for parts of Connecticut, Massachusetts and Rhode Island.
Governors of Virginia, Maryland, West Virginia and Delaware declared states of emergency.
Some parts of Virginia had already received more than two feet of snow. Parts of Maryland had recorded 22 inches (56 cm).
VDEM said the storm has knocked out power to over 71,000 customers statewide.
Weather conditions in the capital area? hit by blowing snow coupled with cold and windy conditions? made travel "extremely treacherous," NWS warned, advising residents to avoid travel.
Authorities reported many drivers and passengers had been stranded in their vehicles, some for more than 12 hours. Greyhound Lines, the country's biggest provider of bus transportation, said most of its services across the eastern seaboard had been cancelled or delayed.
