The additional power outages could stall recovery efforts, even though utility companies had prepared, adding extra crews ahead of the nor'easter.
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.
Paul Farash, of West Babylon, N.Y., said he got power back after three days and didn’t lose it again.
‘‘Whatever I experienced was minimal compared to a whole lot of other people,’’ he said. ‘‘I've seen some things. I've heard about some things. and I know some things. And I'm counting my blessings. I'll survive.’’
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.
