CHEYENNE, Wyo. — A late spring snowstorm returned much of the Wyoming landscape to more of a winter scene and hampering travelers.

The Wyoming Department of Transportation closed a 50-mile stretch of Interstate 80 between Cheyenne and Laramie on Thursday because nearly a foot of snow had fallen. The highway was expected to remain closed most of the day. Eastbound lanes of I-80 from Rock Springs to Laramie were closed to ease traffic backed up west of Laramie.

Winter storm warnings were posted Thursday for areas that included Cheyenne, Laramie, Wheatland and Lusk. Up to a foot of snow was possible in Laramie with up to several feet in surrounding mountains.

Sporadic power outages occurred from snow weighing down tree branches.

Casper, Rawlins and Riverton were under a winter weather advisory.
