New York — The Christmas Blizzard of 2010 howled into New York on Sunday night, crippling road, rail and air transportation on one of the busiest holiday travel days of the year.
The National Weather Service said 18 to 20 inches of snow would fall by midday Monday, with 2 feet or more in some places.
By evening, gale-force winds were blowing the snow horizontally, and lightning was flashing amid the swirling flakes, a phenomenon known as thundersnow.
States of emergency were declared from North Carolina to Massachusetts, and airports up and down the Eastern seaboard, including Kennedy and Newark Liberty airports, suspended all air traffic Sunday.
More than 1,400 flights in and out of New York were canceled Sunday alone.
