Highlights

Skiers and riders that choose to enter major, active avalanche paths where the October rain crust and facet combination is present could trigger very large and dangerous slab avalanches. Make conservative terrain choices and come home to your friends and family this holiday season. In very steep, wind-loaded terrain above 7,500 feet, skiers and riders might still be able to trigger a pocket of wind slab up to 18 inches in depth.

    On northwesterly to northeasterly aspects above 9,000 feet, deep slabs lie upon faceted snow and hard crusts. A single skier or rider might still be able to impact this weak layer and trigger a very large, destructive avalanche with slab depths up to five feet. Large triggers, such as snowmobiles, are more likely to cause failure of this weak layer. Previous tracks are not an indication of stability with a deep slab problem.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Southerly flow will veer to the southwest and eventually to the northwest as an upper level low pressure system tracks across northern Utah and Colorado. By Sunday evening, storm totals could reach 12 to 18 inches in favored locations. Overnight lows in the mountains will be in the low teens and only rise a couple of degrees during the day. Southerly ridgetop winds at 15 to 25 miles per hour will veer to the northwest and decrease to 5 to 15.The avalanche hazard is comprised of both the likelihood of trigger a slide and the consequences of being caught. On Christmas day, the deep persistent slab problem will continue to be a significant concern. Skiers and riders that choose to enter major, active avalanche paths where the October rain crust and facet combination is present could trigger very large and dangerous slab avalanches to depths of six feet. Large triggers, such as snowmobiles, are more likely to be able impact this weak layer. Due to the consequences of these deep, hard slab avalanches, the hazard will remain CONSIDERABLE above 9,000 feet. In steep, wind-loaded avalanche terrain, backcountry travelers could also trigger newly developed wind slabs and loose snow sluffs.
