Forecasters warn more snow is on the way to parts of the Colorado Rockies that have already seen up to four feet of it---leading to huge drifts and road-closing avalanches.
Some areas in the San Juan Mountains could get up to five feet of snow before the system moves out.
Winds of up to 80 miles-per-hour created drifting problems, and four passes in western Colorado had to be shut down for hours.
Four snowmobilers were also trapped over the weekend on Rabbit Ears Pass near Steamboat Springs. They were rescued without injury Sunday morning.
The statewide avalanche danger is "considerable," midway on a five-step scale.
While snow fell in the high country, it rained in the valleys -- where temperatures were higher.
Between 1 and 2 inches of rain fell in the Four Corners region between Friday and Monday, more than usually falls in the area during the entire month of January.
The latest storm system isn't expected to affect the eastern half of the state. Experts say the air usually dries out and stabilizes once the system passes over the mountains.
Skiers are happy though. Silverton Mountain ski area has received two feet of new snow over the weekend; Crested Butte-17 inches; Durango-11 inches and Aspen Highlands-10 inches.
