Winter Storm Brings Icy Temperatures and Cuts Power Across U.S.

A coast-to-coast winter storm swept from Oregon and Washington to the Southeast on Sunday, part of a frigid weather pattern that created record low temperatures in Minnesota and a 100-vehicle traffic pileup in Texas and that is now producing dangerous conditions across much of the country because of heavy snowfall, perilous ice and dangerously low temperatures.

The National Weather Service said early Monday that at least 150 million Americans were under ice or winter weather advisories. Hundreds of thousands of people were without power. Trucks slid off highways and cars piled up on ice-coated roads. As the storm continued to intensify, officials urged residents to brace themselves.
