New York Mayor Michael Bloomberg has ordered the rationing of gasoline in New York City due to the shortage caused by superstorm Sandy.

Bloomberg said the effects of the storm caused "disruptions in the orderly sale of motor fuel," which "imperil public safety." 

Gasoline will be available to drivers with license plate numbers ending in an odd number starting Friday morning. Drivers with plate numbers ending in an even number can gas up on Saturday.

Only 25 per cent of the city's gas stations are open, Bloomberg said. He estimated the tight gas supplies could last another couple of weeks.

Damage in New York state from superstorm Sandy could total $33 billion when all is said and done, Gov. Andrew Cuomo said Thursday as the state began cleaning up from a nor'easter that dumped snow, brought down power lines and left hundreds of thousands of new customers in darkness.

A damage forecasting firm had previously estimated that Sandy might have caused between $30 billion and $50 billion in economic losses from the Carolinas to Maine, including property damage, lost business and extra living expenses. Cuomo's estimate will likely pushes the bill even higher.

A damage estimate of even $50 billion total would make Sandy the second most expensive storm in U.S. history, right behind Hurricane Katrina. Sandy inundated parts of New York City and New Jersey with a storm surge that topped four metres in some areas, killed more than 100 people and left more than 8.5 million people without power at its peak.

On Thursday, a nor'easter that stymied recovery efforts from Sandy pulled away from New York and New Jersey, leaving hundreds of thousands of new people in darkness.

From Brooklyn to storm-battered sections of the Jersey shore and Connecticut, about 750,000 customers — more than 200,000 from the new storm — in the region were without power in temperatures near freezing, some living for days in the dark.

"We lost power last week, just got it back for a day or two, and now we lost it again," said John Monticello, of Point Pleasant Beach, N.J. "Every day it's the same now: turn on the gas burner for heat. Instant coffee. Use the iPad to find out what's going on in the rest of the world."

But most were just grateful the new storm didn't bring a fresh round of devastation.

"For a home without power, it's great. It came through the storm just great," said Iliay Bardash, 61, a computer programmer on Staten Island without electricity since last week. "But things are not worse, and for that I am thankful."

Unlike other holdouts who got by with generators or gas stoves, the 63-year-old from Ukraine has been without power since Sandy brought more than two metres of water through his door and his neighbour's deck into his yard. He tried to beat the cold Wednesday night by sleeping with his Yorkie, Kuzya, and cat, Channel.

"I had the dog right here," he said, pointing to his left side, "and the cat on my chest. It was still too cold, but I cannot leave my house."

Throughout Staten Island's beach area, the storm had blanketed growing piles of debris with several inches of snow. By mid-morning, it was starting to melt, filling the streets with filthy sludge.

Airlines cancelled hundreds of flights before and during the new storm. On Thursday, there were about 600 cancelled, according to flight tracking service FlightAware, mostly in the New York area.

But roads in New Jersey and New York City were clear for the morning commute, and rail lines into New York were running smoothly so far, despite snow still coming down heavily in some areas.

The nor'easter, as promised, brought gusting winds, rain and snow, but not the flooding that was anticipated.

In New Jersey, there were about 400,000 power outages early Thursday; 150,000 of those were new. In New York City and Westchester, more than 70,000 customers were without power after the storm knocked out an additional 55,000 customers.

For Consolidated Edison, the extra outages were dealt with swiftly, so there were only about 3,000 additional customers without power from the total Wednesday of 67,000.

"I think we're going to be able to power through. Our objective was to get power restored to everyone by the weekend and we're still working with that goal," said Alfonso Quiroz, a spokesman for the utility.

On Long Island, an area badly battered, there were 125,000 new outages, but about 80,000 were restored, making a total of about 300,000 customers without power. Long Island Power Authority spokesman Mark Gross said the utility was assessing new damage while working to restore outages.

Residents from Connecticut to Rhode Island saw seven to 15 centimetres of snow on Wednesday. Worcester, Mass., had 20 centimetres of snow, and Freehold, N.J., had just over 30 centimetres overnight. Some parts of Connecticut got a foot or more.

There was good weather news: temperatures over the next few days will be in the 50s in southern New England, said meteorologist Frank Nocera, and on Sunday it could edge into the 60s.

CBC meteorologist Jay Scotland said Atlantic Canada will deal with some messy weather today thanks to the nor’easter. Nova Scotia will be hit by wind and rain while New Brunswick will see a messy mix pushing north. 

New Brunswick will receive a mix of snow and rain, Scotland said, with possible freezing rain, ice pellets and wet snow to the north. Newfoundland will also see wet and windy weather today.
