CHEYENNE, Wyo. (AP) — A 150-mile section of Interstate 80 between Cheyenne and Rawlins is closed because of heavy snow and weather-related accidents.

The Wyoming Highway Patrol reports some 60 cars and trucks involved in about three separate pileups about 15 miles west of Cheyenne on both sides of the highway. No fatalities have been reported but the Highway Patrol reports multiple injuries.

The National Weather Service has posted winter storm warnings and winter weather advisories for southeast Wyoming, including Cheyenne and Laramie. Up to a foot of snow is possible in the surrounding mountains.

Snow lingered Thursday in areas of central Wyoming where more than a foot of snow fell Wednesday in some mountains. Lander received about 6 inches and Cody 4 inches.

Meanwhile officials with Cheyenne Regional Medical Center said as of 4 p.m. that they had treated 11 patients who were brought in from the crash area.

As many as 11 other crash victims were reported to be en route to the hospital for treatment

CRMC spokeswoman Kathy Baker said another 20 people who were reported to be stranded by the wreckage, but not injured, were also reported to be en route.

The American Red Cross was sending volunteers to the hospital to help arrange for shelter, according to Baker,
