Snow blanketed parts of the northeast United States on Tuesday as a blizzard rolled in, with residents being advised to stay at home, airlines grounding flights and schools canceling classes.

Boston Braces for Snow
The storm comes near the end of an unusually mild winter along much of the East Coast, with below-normal snowfalls in cities such as New York City and Washington, D.C.
Boston was braced for up to a foot of snow, which forecasters warned would fall quickly during the storm’s peak. Washington D.C., a city which functions badly with even small amounts of snow, was expecting 5 inches (13 cm) and twice that in outlying areas.
Snow fall will be heavy at times with as much as 4 inches an hour expected to fall with winds reaching up to 60 mph (100 kph) in parts of the northeast, the National Weather Service warned.
“Visibilities will become poor with whiteout conditions at times,” it said.
