In sintesi

At the mid and upper elevations, 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. Avalanches are unlikely at the lower elevations.

    Above 7,500 feet, backcountry travelers might be able to trigger wind slabs to depths of one to three feet in steep, wind loaded terrain.

    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

A northwest flow with limited moisture will bring partly to mostly cloudy skies to the area. Periods of light snowfall with little accumulation are possible in the mountains. Temperatures will remain in the teens and 20s. Winds will be northwest to west at 10 to 20 miles per hour with higher gusts.The general avalanche hazard is expected to be MODERATE at the upper elevations where humans could trigger wind slab avalanches 6 to 30 inches deep in steep avalanche prone terrain. Some potential may persist for full depth slab avalanches on steep northerly aspects. Avalanches are unlikely at the mid elevations except in isolated pockets and are unlikely at the lower elevations.
