"We still have some areas that we have to do a lot more work on. But we've come through it pretty well," de Blasio said on ABC's "This Week." "I think tomorrow is going to be pretty good."

The blizzard was the second-biggest snowstorm 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 (68.3 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. One person died in Maryland and three in New York shoveling snow. Two died of hypothermia in Virginia, and one from carbon monoxide poisoning in Pennsylvania.
