A powerful winter storm engulfed the US Northeast on Monday, blanketing much of the region in heavy snow, blasting coastal areas with high winds and bringing New York City and other major urban centers to nearly a standstill. The nor'easter - an East Coast storm with winds blowing from the northeast - could bring accumulations of 1 to 2 feet (31 cm to 61 cm) to the country's most densely populated region before tapering off on Tuesday, the National Weather Service said.
