Avalanche Summary

No recent avalanches were reported.

Snowpack Summary

Recent N and NE winds have developed 10 to 40 cm thick windslabs on lee and cross-loaded alpine featured. In sheltered terrain, about 20 cm of dry light snow is sitting on a surface hoar layer, on old unreactive wind slabs or a melt-freeze crust on previously sun-exposed slopes. Cold temperatures are continuing to transform snow into facets at the surface or all the way down to the ground where the snowpack is thinner. The deep persistent weak layers are not as much of a concern at this moment because of the relatively stable weather pattern.
