The governors of New York and New Jersey lifted travel bans they had imposed a day earlier and New York City's subway system was set to restart, though officials urged people who did not have to drive to stay off snow-covered roadways.
A blizzard warning remained in effect for much of Massachusetts and Rhode Island, where snow was expected to go on falling through the day at a rate as high as 2 to 3 inches (5 to 8 centimeters) an hour, even as the National Weather Service lifted its blizzard warning for the New York City area.
Some in New York criticized the aggressive warnings of officials including Mayor Bill de Blasio, who for the first time in history ordered the city's subway to close for a snowstorm. Officials with vivid memories of disasters including 2012's Superstorm Sandy defended their actions.
Some cab drivers in New York doubled fares and sought to pack additional passengers into their vehicles as office workers headed to their jobs.

Travel was still snarled, with more than 4500 flights cancelled at US airports, according to FlightAware.com.
'PLAYING IT SAFE'
New Yorkers were divided on whether officials had over-reacted in ordering dramatic shutdowns ahead of the storm.
"The mayor might have blown it this time but he was probably just playing it safe," said Manny Martinez, 55, as he salted his driveway in New York's Brooklyn borough. Martinez said he was glad to find his shoveling work easier than he had expected.
"This is what I was praying for, the white fluffy stuff."
Others were frustrated that de Blasio had preemptively shut the subway and ordered cabs off the roads.
"It's never as bad as they say it is going to be," said Greg Noble, 29, as he walked briskly to his maintenance job some 30 city blocks from his Manhattan home. "This made it a little difficult to go to my job. I usually take a taxi, but no taxis today."
New York Governor Andrew Cuomo defended the decisions, which had included a driving ban in New York City and its surrounding counties overnight.
"I would rather, if there is a lean one way or another, lean towards safety because I have seen the consequences the other way and it gets very frightening very quickly ... we have had people die in storms," Cuomo told reporters. "I would rather be in a situation where we say 'We got lucky.'"
His New Jersey counterpart, Governor Chris Christie, was less sanguine about the dire forecasts that preceded the storm.
"I wasn't thrilled on my 5:30 a.m. phone call, but it's the way it goes," Christie told Philadelphia's WTXF television.
CONNECTICUT, MASSACHUSETTS HARDEST HIT
Some of the heaviest snowfall was recorded in parts of Connecticut and Massachusetts, with about 50cm reported in around Worcester, well over the 15cm reported in New York City's Central Park.
New York's Suffolk County, east of New York City, also saw 60cm of snow in spots.
Fewer Massachusetts residents and businesses lost power than was expected, said Governor Charlie Baker, saying that temperatures well below freezing had resulted in light snow. High winds could yet result in additional outages, he said.
"We'll continue to see high winds throughout the course of the day," Baker told reporters on Tuesday. "People should spend the morning digging out, cleaning up."
Significant flooding was reported in coastal communities south of Boston, including Scituate, the state police said.
