Highlights

Dangerous deep persistent slab avalanches are still a concern on steep slopes. Backcountry travelers also may be able to trigger an isolated pocket of wind slab up to a foot in depth on leeward slopes above 9,000 feet. At the lower elevations overnight temperatures were near freezing. Down there watch for unstable conditions on very steep terrain features and be aware of the potential for roofs to slide.

    Humans could trigger deep persistent slab avalanches in steep terrain . Although the likelihood for these large slab avalanches to be human triggered continues to slowly decrease the consequences of triggering a slab avalanche 3 to 7 feet deep are likely to be fatal. These dangerous slab avalanches are most likely to be triggered when a person crosses of a thin spot in the slab or by a larger trigger like a snowmachine.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )The upper elevation flow will continue to favor the higher elevations of the western portions of our forecast areas. Skies will remain mostly cloudy. Another 3 to 6 inches of new snow may accumulate in the favored locations by tomorrow evening. Less favored areas could receive 2 to 4 inches. A trace to an inch is likely in the valleys. Temperatures will be in the upper teens and 20s in the mountains and in the 20s and 30’s at the lower elevations. Winds will be from the west at 10 to 15 miles per hour with higher gusts.At the higher elevations small pockets of wind slab could be triggered by skiers and riders in steep wind loaded avalanche starting zones. These small surface slabs could be 6 to 18 inches deep and could quickly become a significant hazard in steep chutes and cliff areas. Some potential continues for humans to trigger deep persistent slab avalanches. Although the likelihood for these dangerous slab avalanches to be human triggered continues to slowly decrease the consequences of triggering a slab avalanche 3 to 7 feet deep are still likely to be severe. Avalanches are unlikely at the lower elevations except on isolated terrain features. The general avalanche hazard is expected to be moderate above an elevation of 7,500 feet and low below that elevation.
