Highlights

In the mountains, persistent slabs continue to pose a serious threat to backcountry travelers. The consequences of triggering one of these slabs are likely to be severe. Careful terrain and snow pack evaluation is warranted. The snowpack is mostly stable below 7,500 feet, and avalanches are unlikely.

    Hard slabs, with depths to four feet, lie upon persistent weak layers of faceted snow near the base of the snowpack on a variety of aspects. Large triggers, such as groups of people or snowmobiles, may be necessary to cause failure of these basal facets. However, the chance continues for a single person to trigger one of these hard slabs, particularly in a shallow area where those weak layers are more easily impacted. Previous tracks and the lack of recent avalanche activity are not indications of stability.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Light, scattered flurries will remain possible at times on Saturday. Overnight temperatures in the mountains will be in the upper single digits before rising into the mid-teens during the day. Westerly to northwesterly ridgetop winds will range from 10 to 20 miles per hour.The general avalanche hazard will continue to be Moderate above 7,500 feet on Saturday. There, the chance continues for backcountry travelers to trigger large, hard slab avalanches that lie upon deeply buried weak layers of faceted snow. Large triggers, such as groups of people or snowmobiles, may be necessary to cause failure of these basal facets. However, the chance continues for a single person to trigger one of these hard slabs, particularly in a shallow area where those weak layers are more easily affected. Avalanches are unlikely below 7,500 feet.
