A snowshoer changes socks and shoes before starting out on a trek in freshly-fallen snow at Snoqualmie Pass, Wash., this week. A weather pattern that could be associated with El Nino has turned winter upside-down across the U.S. during a week of heavy holiday travel, bringing spring-like warmth to the Northeast, a risk of tornadoes in the South and so much snow in parts of the West that there are concerns about avalanches. On Christmas Day, it could be warmer in New York City than Los Angeles. (AP Photo/Elaine Thompson)
