NEW YORK: The American north-east is slowly digging out from a mammoth blizzard that caused at least seven deaths, cut power to about 650,000 homes and businesses and choked air, road and rail travel.
The storm, which hit New York and other areas still scarred by hurricane Sandy in October, dumped almost a metre of snow across New England, with hurricane-strength gusts creating massive drifts.

Hundreds are stranded as a record-breaking blizzard pummels the US Northeast, leaving at least five people dead.
By late Saturday, the system had moved north, battering three Canadian provinces.
New York area airports LaGuardia, John F. Kennedy and Newark, which halted all flights during the height of the storm on Friday, resumed services with delays.
FlightAware.com listed almost 2000 cancellations around the region, on top of the 3000-plus flights scrapped on Friday.
The blizzard engulfing Boston's Logan Airport was so severe that ploughing operations were abandoned for several hours, but authorities said arrivals would resume on Saturday evening and departures on Sunday.
Amtrak said its rail link between New York and Boston would remain closed until Sunday but trains were resuming normal schedules to Washington.
A driving ban in Massachusetts, where more than half a metre of snow buried Boston streets during the blizzard, was lifted on Saturday afternoon.
''We have a lot of snow to dispose of and to remove and it will take some time to do that. That is a necessary prerequisite to getting to power lines and getting power restored,'' the Massachusetts Governor, Deval Patrick, said. The Connecticut Governor, Dannel Malloy, lifted a similar ban but urged people to stay home.
''It's critical right now that residents stay off the roads, so that our ploughs can continue their efforts to clear our streets and highways,'' Mr Malloy said.
''This is a record-setting storm. It's going to take time to dig out of the snow. Stalled or abandoned vehicles will only slow that process.''
The almost deserted roads were still highly dangerous.
Eighty centimetres of snow in Portland, Maine, is the most recorded there from a single snowstorm, officials said.
The death toll from the storm was seven as of Saturday. Two people died in car accidents and an 11-year-old Massachusetts boy died when he and his father inhaled carbon monoxide after their car's exhaust pipe was blocked by snow. Four other storm-related deaths were reported in Connecticut.
The US Federal Emergency Management Agency said liaison officers have been positioned in state emergency operations centres in Connecticut, Massachusetts, New Hampshire, New Jersey, New York (in Albany and New York City), Rhode Island, and Vermont.
But in New York City most roads were cleared by morning.
''Looks like we dodged a bullet,'' the mayor, Michael Bloomberg, said. At noon the sun came out, and people with sleds flocked to parks and took photographs.
With the wind and heavy snow snapping power lines, more than 650,000 buildings lost electricity, including about 400,000 in Massachusetts, 187,000 in Rhode Island, and 35,000 in Connecticut.
Utility companies in Connecticut expect up to 30 per cent of their customers, or more than 400,000 homes, to eventually lose power.
