CHEYENNE, Wyo. (AP) - A powerful spring snowstorm continues to bring highway traffic to a halt across most of southern Wyoming.
The storm has closed Interstate 80 from Cheyenne to Rawlins and eastbound from Rock Springs to Cheyenne.
The National Weather Service has issued a winter storm warning from Rock Springs to the Nebraska line through Monday morning. Winter weather advisories are in effect for Evanston, Green River, Lander and Douglas.
The Weather Service says mountainous areas could get a foot or more of snow. Five to nine inches are forecast for Cheyenne, Laramie and Rawlins with lesser amounts elsewhere.
Temperatures in most of Wyoming will dip into the 20s overnight before climbing back above freezing Monday.
The weather is forecast to gradually warm up again over the remainder of the week.
