COOKE CITY, Mont. (AP) — An avalanche warning is in effect for the mountains around Cooke City after more heavy snow swept through the area.

The Gallatin National Forest Avalanche Center said Sunday the risk of avalanches is high due to over a foot of new snow and strong wind.

Forest officials say people already were triggering avalanches in the area before the storm. An avalanche on Wednesday killed a snowmobiler from North Dakota. He was buried by 8 feet of snow not far from Cooke City.

Forest officials are urging people to keep out of places prone to avalanches.

They say avalanche risk is considerable in the Bridger, Gallatin and Madison ranges of southwestern Montana and moderate in the Teton Range, Wyoming Range and Togwotee Pass areas in northwestern Wyoming.
