Avalanche Summary

You could trigger avalanches on steep slopes where you observed around 8 inches of new snow or more. Avalanches in the new snow will test deeper buried weak layers and could step down, triggering a larger slide. Steep northerly and easterly slopes have been the most recent culprits for larger avalanches and were triggered from a shallow area. To dodge this problem, avoid slopes steeper than around 35 degrees altogether.

Warming temperatures and ample sunshine will warm the most recent storm snow. Loose avalanche activity is expected on steep, sunny, and rocky slopes, with the probability of natural and human-triggered avalanches increasing during the day. Most avalanches will remain small but could be dangerous if pushed into terrain traps like gullies, trees, or cliffs. Avoid steep slopes that show signs of warming in the form of rollerballs, pinwheels, or recent avalanche activity on similar slopes.
