Power was restored to lower Manhattan and some other areas overnight and Saturday, but it was still lights out for 2.5 million homes and businesses as temperatures were dipping into the 20s in communities like hard-hit Rockaway and the entire region braced itself for a potential nor'easter next week that could even bring snow.

Overnight lows will be around 28 degrees F in Rockaway, 38 in New York City and 33 on parts of Long Island, NBCNewYork.com reported. Even in areas with temps above 30, 15-20 mph winds will make it feel like it's in the 20s.

Temperatures Sunday and Monday were expected to be even colder just as critical heating oil supplies dwindle.

"There's no heating oil around," said Vincent Savino, the president of Statewide Oil and Heating, which usually supplies some 2,000 buildings across New York City. "I don't know how much fuel we have left: maybe a day or two."?

Chances for a slow-moving nor'easter, meanwhile, are "increasing," the National Weather Service's prediction center said in a Saturday morning update.

"If the storm tracks close enough to the coast," it added," it appears the airmass may be sufficiently cold for snow to fall, even in the lower elevations."

Expected to be felt in the Northeast on Wednesday and Thursday, the storm would not be anywhere as destructive as Superstorm Sandy, but could cause some new erosion and hinder recovery efforts.

"The general impacts will include another round of brisk winds, rainfall and chilly temperatures for the recovery areas along the coast," weather.com winter weather expert Tom Niziol posted in a Saturday update.

He expected 1-2 inches of rain in coastal areas and 25-30 mph gusts on Wednesday, adding that the forecast could change.

"We do not expect the impacts to 'break anything that is not already broken'," he added. "However the combination of weather impacts will add insult to injury for the recovery process along the East Coast."

FEMA and Red Cross officials said Saturday they were mobilizing even more resources to prepare for the storm.

In New Jersey, Gov. Chris Christie on Saturday visited crews repairing the berm in Little Ferry, saying a push was being made to seal it up before the new storm.?Sandy tore up the berm, causing widespread flooding there.

The U.S. death toll reached 109 on Friday, after Sandy killed 69 people as a hurricane in the Caribbean. It struck the New Jersey coast on Monday as a rare hybrid after the hurricane merged with a powerful storm system in the north Atlantic.

Consolidated Edison, a utility battling what it called the worst natural disaster in its history, restored electricity to New York City neighborhoods such as Wall Street, Chinatown and Greenwich Village in the pre-dawn hours.

The Home Depot has sent 5,000 truckloads of supplies into the East Coast since last Tuesday. Getting essentials to stores in ravaged communities takes a team of people working in what they call a "War Room." NBC's Gabe Gutierrez reports.

But some 11,000 customers in Manhattan were still without power.

"There's enough light and activity to get a lot of people on the street and get rid of that movie-set look as if we're in some kind of ghost town or horror movie," Con Ed spokesman Bob McGee told NY1 television.

In New Jersey, the utility PSE&G said 612,000 customers were still without lights after power to 1 million had been restored.

Con Ed said it had restored power to 70 percent of the 916,000 customers in the New York City area who were cut off. The company was still busy assisting tens of thousands more without power in New York City's outer boroughs, where some people complained of being ignored.

With collapsed roads and destroyed homes along the New York area shore, the changes have altered the coastline and accelerated beach erosion. NBC's Kerry Sanders reports.

"We have nobody down here with video coverage," said Grace Lane, a grandmother who defied evacuation orders and rode out the storm in her second-story bedroom as water rushed through the first floor of her house in Broad Channel, a community in Queens.

Eight people -- Lane, her husband, their two daughters, their husbands and her two grandchildren -- were sleeping on air mattresses on the floor of the upstairs bedroom, the last usable room in the house.

"At least my children are OK," she said.

In a city devastated by Sandy, holding a race through five battered boroughs just seemed like the wrong idea, according to officials. "I think there's a thin line between demonstrating resilience and being insensitive," one runner said. NBC's Stephanie Gosk reports.

Many houses were gutted by 5 feet of floodwater that raced through Broad Channel, where residents hauled broken furniture and soggy belongings out of their homes on Friday.

In a sign of security worries in the neighborhood, one garage full of debris stood open with a sign next to it reading: "LOOTERS WILL BE CRUCIFIED - GOD HELP YOU."

Moving to ease fuel shortages, the Obama administration directed the purchase of up to 12 million gallons of unleaded fuel and 10 million gallons of diesel, to be trucked to New York and New Jersey for distribution.

With hundreds displaced by the storm, crucial necessities are being supplied to those hit hardest by Sandy by FEMA, the Red Cross and the National Guard. NBC's Michelle Franzen reports.

The government announced it would tap strategic reserves for diesel for emergency responders and waived rules that barred foreign-flagged ships from taking gas, diesel and other products from the Gulf of Mexico to Northeast ports.

The moves could help to quell anger triggered by growing lines -- some of them miles long -- at gas stations. Less than half of the stations in New York City, Long Island and New Jersey were operating on Friday.

New Jersey Gov. Chris Christie ordered gas rationing in 12 counties to begin on Saturday under an "odd-even" system in which motorists with license plates ending in odd numbers would be able to buy gas on odd-numbered days.

Experts say flooding in the Big Apple can be prevented in the future by building seawalls, levees or gigantic surge barriers. NBC's Richard Engel reports.

Disaster modeling company Eqecat estimated Sandy caused up to $20 billion in insured losses and $50 billion in economic losses.

At the high end of the range, it would rank as the fourth costliest U.S. catastrophe, behind Hurricane Katrina in 2005, the September 11, 2001, attacks and Hurricane Andrew in 1992, according to the Insurance Information Institute.
