At the higher elevations skiers and riders who venture into steep avalanche starting zones and cliff areas could trigger pockets of wind slab 6 to 18 inches deep. These slab avalanches will become more sensitive to human triggers as the day warms. It will get warm today. Temperatures are forecast to rise into the mid 30's on the summits, to near 40 degrees at the mid elevations and into the mid 40's in the valleys. These warm temperatures and abundant sunshine will increase the wet snow avalanche hazard. Wet snow avalanches are possible on steep sunlit aspects. Avoid steep terrain and overhanging hazards after snow surfaces significantly soften.

A strong cold front will blast through western Wyoming tomorrow morning. This system could bring 2 to 5 inches of new snow to the mountains tomorrow morning. It will be accompanied by wind gusts that could exceed 60 miles per hour. The combination of strong winds and a relatively short period of intense snowfall may create white out conditions. Temperatures at elevation will be in the teens during the day and drop to near zero by Tuesday morning. At the lower elevations, temperatures will remain in the 20s during the day and drop into the single digits overnight.The cold temperatures will mitigate the wet snow avalanche hazard. A period of intense snowfall and strong winds may form some new shallow wind slabs at the higher elevations. These new slabs are expected to be small and less than a foot deep. Pockets of older wind slabs can also be found in some areas at the highest elevations. On Monday the general avalanche hazard is expected to be low below an elevation of 9,000 feet and may be moderate at the higher elevations during passage of the cold front when snowfall rates exceed an inch an hour.
