Massive winter storm brings snow and freezing temperatures to US

Tens of millions of Americans have endured bone-chilling temperatures, blizzard conditions, power outages and cancelled holidays after a winter storm that forecasters said was nearly unprecedented in its scope. The conditions exposed 60% of the US population – more than 200 million people – to some sort of winter weather advisory or warning. The US National Weather Service’s map “depicts one of the greatest extents of winter weather warnings and advisories ever”, forecasters said.
