Highlights

The general avalanche hazard is MODERATE above 7,500 feet. There, skiers and riders might be able to trigger wind slabs in steep, wind loaded terrain. On northerly aspects above 9,000 feet, these surface slabs still have some potential to step down and release deep persistent slabs failing near the ground. Large triggers, such as snowmobiles or big groups, may be needed to directly trigger these deep persistent slabs. Below 7,500 feet, the general avalanche hazard is LOW and avalanches are unlikely.

    Weak, faceted snow exists at the base of the snow pack on shaded aspects above 9,000 feet. On steep avalanche prone slopes, some potential remains for backcountry travelers to trigger dangerous, full depth hard slab avalanches on this persistent weak layer. Large triggers, such as snowmobiles, are more likely to be able impact this deep weak layer. However, skiers could also cause failure if they hit a shallow weak spot connected to deeper snow. Previous tracks should not be interpreted as a sign of stability.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Cloud cover will increase during the day ahead of a weak cold front and associated disturbance which will bring a chance for light, scattered snow showers in the afternoon. Overnight lows in the mountains will be near 10 before rising into the upper teens during the day. Westerly ridgetop winds will range from 15 to 25 miles per hour.Above 7,500 feet, the general avalanche hazard is expected to be MODERATE on Friday. Backcountry travelers venturing into steep, wind loaded terrain might be able to trigger recently developed wind slabs one to three feet in depth. These slabs lie upon a variety of sliding surfaces and weak layers including suncrusts, wind pack, near surface facets and surface hoar. On steep, northerly aspects above 9,000 feet, these slabs might be able to step down to weak, faceted snow near the base of the snowpack. Large triggers, such as snowmobiles or big groups, may be needed to directly trigger these deep persistent slabs. The general avalanche hazard is expected to be LOW below 7,500 and avalanches are unlikely.
