New York lifted a travel ban and mass transit started getting back to normal on Sunday after a near-record blizzard in the U.S. Northeast.
Washington, however, remained at a standstill following storms that killed at least 19 people across the country.
Some 7,000 flights were cancelled during the weekend, with forecast that the disruption would continue during the week.
The storm was the second-biggest in New York City history, with 26.8 inches (68 cm) of snow in Central Park by midnight on Saturday, just shy of the record 26.9 inches (68 cm) set in 2006, the National Weather Service said.
Thirteen people were killed in weather-related car crashes in Arkansas, North Carolina, Kentucky, Ohio, Tennessee and Virginia on Saturday. One person died in Maryland and three in New York while shoveling snow. Two died of hypothermia in Virginia, officials said.
The heaviest fall was recorded in Shepherdstown, West Virginia, which had at least 103cm of snow.
At least 85 million people have been affected by the storm, dubbed Snowmageddon and Snowzilla on social media, while more than 200,000 people are experiencing power outages.
New York Mayor Bill de Blasio said Sunday would be a major clean-up day. He urged residents to stay off streets so city crews could clear roads.
“We still have some areas that we have to do a lot more work on. But we’ve come through it pretty well,” he said on ABC’s “This Week with George Stephanopolous.”
“The snow pile is going to be with us for a while, but I think we’ll be in good shape in the next 24 hours,” de Blasio said.
After the storm moved out into the Atlantic Ocean, much of the Northeast was expected to see a mix of sun and clouds on Sunday with temperatures just above freezing.
New York state Governor Andrew Cuomo lifted a travel ban on New York City-area roads and on Long Island at 7 a.m. (1200 GMT) on Sunday. A state of emergency declared by Cuomo was still in place.
Most bus and subway services operated by the Metropolitan Transportation Authority were up and running again by 9 a.m. (1400 GMT), officials said, and the agency was working on restoring full service on Sunday.
The Metro-North rail line, which serves suburbs north and east of New York City, expected to have commuter train service running into and out of New York by 3 p.m. (2000 GMT) on Sunday. A spokeswoman for the New York Stock Exchange said the market planned to open as usual on Monday.
