    Small but reactive wind slabs have been reported on a range of aspects, including lower elevations than usual. Expect the most reactive slabs in immediate lee terrain, such as just below ridgetops.

Confidence

High

  • The number, quality, or consistency of field observations is good, and supports our confidence.

Avalanche Summary

Wind slab activity has decreased since late last week, when several size 1 to 2 natural and explosive-triggered avalanches occurred. However, recent blowing snow suggests newer slabs may still be present and triggerable.

Snowpack Summary

Strong, shifting winds have heavily affected alpine and treeline terrain, building wind slabs on many aspects and in some places extending well into the trees. The snowpack is generally deep and simple for the time of year, with treeline depths exceeding 300 cm.
