Avalanche Summary

No new avalanches reported.

Snowpack Summary

A solid melt-freeze crust has developed at all elevations on most aspects. New snow may bury surface hoar that has grown at and below treeline over the past few days. In the alpine new snow may not bond to the old surface depending on the timing of the cooling. Deeply buried weak layers continue to exist, however the bridging effect of the re-frozen upper snowpack may reduce the likelihood of triggering.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
