In sintesi

Some potential persists for backcountry travelers to trigger surface slabs in steep terrain at the mid and upper elevations. The snowpack is mostly stable at the lower elevations and avalanches are unlikely.

    Snowfall over the weekend was accompanied by southwesterly to westerly ridgetop winds. This scenario was followed by moderate to strong northerly to northeasterly ridgetop winds which redistributed snowfall and stiffened wind slabs. Skiers and riders could trigger these slabs with depths of one to two feet on a variety of aspects above 7,500 feet. The likelihood of triggering these slabs will decrease with a drop in elevation where winds were less of a factor.

Avalanche Discussion

Inverted temperatures will continue on New Year's Day. Overnight lows in the mountains will be near zero as the valleys drop back into the negative teens. Mountain highs will be near 20, and the lower elevations will climb into the teens. Easterly ridgetop winds will back to the north at 10 to 15 miles per hour.The general avalanche hazard is expected to be MODERATE above 8,000 feet on Wednesday. Slab avalanches, one to three feet in depth, could be triggered by backcountry travelers in steep avalanche starting zones and cliff areas. The likelihood of triggering these slabs will decrease with a drop in elevation. The snowpack is mostly stable below 8,000 feet and avalanches are unlikely.
