Dangerous winter storm pummels western U.S.

A dangerous winter storm pummeled parts of the U.S. Rockies and western Plains with heavy snow on Sunday, shutting down Denver's busy airport and forcing the closure of major highways.

The National Weather Service said 3 feet or more of snow was expected to fall in high-altitude areas, and blizzard warnings due to high winds were in effect for parts of Colorado, Nebraska, South Dakota and Wyoming.

In Cheyenne, about 26 inches of snow had fallen by noon, according to the National Weather Service, setting a new two-day record for the city.

More than 57,000 customers were without power in Colorado, according to an outage tracker maintained by utility Xcel Energy. Interstates 70 and 25, Colorado's main roadways, were shut down as of Sunday afternoon. Interstate 80, which runs east-west across Wyoming, was also closed.

The system bringing blizzards to the Rockies was also responsible for severe thunderstorms in Texas, including reports of multiple tornadoes on Saturday. No deaths were reported.
