    With daytime warming loose wet avalanches may still be a lingering problem on steep or unsupported terrain features. These releases may start small but can gain mass quickly.

Avalanche Summary

Numerous small to large loose wet avalanches up to size 2 were observed on solar aspects last week as well as a small natural wind slab avalanche in steep terrain on a northerly aspect in the alpine on Saturday. Warming and cloud cover on Sunday produced pinwheeling and snowballing on all aspects.

Snowpack Summary

Warm temperatures have created a spring-like, melt-freeze cycle on all aspects with the overnight crust breaking down quickly due to the ongoing sunny warm weather. Surface hoar and surface facets may still exist in shaded areas on north aspects. The upper snowpack is well settled and bonding well to the late-November rain crusts although faceting has been noted around these crusts. The lower snowpack is well settled.
