Loose sluffing of new snow is expected in steep terrain. Use increased caution around terrain traps where consequences of a small sluff could be serious.

Avalanche Summary

Reports of small natural and human-triggered loose sluffing from steep terrain features.

Snowpack Summary

The upper and mid-snowpack are generally well consolidated and layers are well bonded. However, a facet/crust weakness near the bottom of the snowpack remains a concern. The depth of this layer makes triggering an avalanche unlikely but the consequences would be large, destructive avalanches. This is referred to as a 'low probability, high consequence' event. We are recommending avoiding thin or rocky areas on steep, convex, unsupported slopes. In most areas, a widespread weak layer is now buried by up to 10cm of new snow. This weak layer consists of large surface hoar (widespread in most sheltered and shaded areas at all elevations), a sun crust on open south facing slopes, facet grains (in colder areas or areas with a thinner snowpack), or a combination of any of the above. This layer may become a problem in the future when we finally get more snowfall.
