"US Braces for Widespread Snow and Ice as Arctic Air Blast Approaches"

A deep freeze continues to grip the U.S. with 68 million Americans under a winter weather advisory, as more cold temperatures, ice, and snow are expected. Widespread wind chill warnings and hard freeze warnings are in place, with severe weather causing school shutdowns and travel chaos. More than 50,000 people are experiencing power outages in Oregon, where half of the 14 deaths attributed to the arctic blast have occurred. Classes have been canceled for millions of students, and authorities in Texas and the Tennessee Valley area are asking residents to voluntarily cut back on electricity use to avoid blackouts caused by high demand.
