Late-season snow and high winds punched through the eastern United States Monday, killing at least three people as the freeze snapped power lines, closed schools and snarled air and road traffic. More than one foot (30 centimeters) of snow fell in parts of the northeastern states of Connecticut, Massachusetts and New Hampshire, the National Weather Service said, as the storm swept toward Canada after paralyzing traffic in southern states during the weekend. Three people died in storm-related traffic accidents in the northeast, including a pregnant woman in Boston, thebostonchannel.com news site reported.
