Snowpack Summary

A wind event from last week formed relatively deep wind slabs in the alpine. New snow combined with wind has formed fresh wind slabs on the surface. The mid-pack is reported to be settling well. Recent reports indicate the late November surface hoar (near the middle of the snowpack) and  early November crust (near the base of the snowpack) have been inactive as of late. It's important to note that professionals are still cautious about these lingering persistent slab problems, but the likelihood of triggering is low. Be wary of steep complex terrain with a shallow snowpack, where triggering a persistent weakness is more likely.
