Highlights

At the higher elevations strong southwest to west winds have formed isolated pockets of wind slab in steep, avalanche starting zones. These small pockets of slab could be 6 to 12 inches deep and could be triggered by a person. Small slides can be dangerous in extreme terrain. At the mid and especially at the lower elevations above freezing temperatures and rain showers will be increasing the wet snow avalanche hazard. Monitor conditions and avoid steep terrain features in areas where the snowpack is wet and unconsolidated. Roof slides are still a concern.

    Temperatures at the lower elevations have been mostly above freezing for multiple days and were well above freezing overnight. Rain showers are possible below an elevation of 9,000 feet and are forecast to become more prevalent in the afternoon. Wet loose and wet slab avalanches are possible on steep terrain features. In areas where the snowpack is shallower these slides could gouge down to the ground. Natural wet snow avalanche activity is possible, especially in areas that receive heavy rain showers.

Avalanche Discussion

Light snow in the mountains will become steadier and heavier through the evening and continue through Tuesday night. Snow will levels will begin rather high, around 9000 feet then gradually fall to around 7500 to 8000 feet tonight. Snow levels will then gradually lower to the valley floors by Tuesday night. Winds will remain gusty and strong at times this evening but decrease gradually tonight. The heaviest snow is expected in the northern zones through Tuesday morning and then may shift into the southern zones later Tuesday into Tuesday night. Twenty-four precipitation totals could be 4 to 8 inches at 10,000 feet with up to a half inch of rain possible at the lower elevations. Temperatures will remain in the upper 20s at elevation and be in the mid-30s overnight and rise into the 40s at the lower elevations. Winds will be from the southwest at 25 to 15 miles per hour with higher gusts. The general avalanche hazard is expected to be moderate. Fresh winds slabs up to two feet in depth formed by southwest to west winds could be triggered by skiers and riders in steep upper elevation avalanche starting zones. Wet snow avalanches will be possible on steep terrain features at the lower elevations. These wet slides could release naturally and gouge down to the ground.
