Massive winter storm sweeps across US bringing ice, frigid temps

A massive winter storm on Saturday dumped snow and freezing rain on New Mexico and Texas as it swept across the United States towards the northeast, threatening tens of millions of Americans with blackouts, transportation chaos and bone-chilling cold.

More than 3,900 flights in and out of the United States were canceled on Saturday alone, and more than 3,000 others were delayed, according to tracker FlightAware. The US federal government preemptively announced offices in Washington would be closed on Monday.
