Kernpunkte

Cornices remain the primary concern. Solar radiation is a common cornice trigger. Limit your exposure when it's cloudy and completely avoid cornices when it's sunny.

Avalanche Summary

No new avalanches were reported on Friday in this region.

Snowpack Summary

10-15 cm of new snow on Saturday with light to moderate southerly winds may have created small wind slabs on lee features below ridgetops. The new snow will likely be sitting on hard surfaces created by strong winds earlier in the week. A weak layer of facets and crusts are buried 100-150 cm down. The layer has been unreactive recently, but rapid warming of the snowpack or a large trigger, such as a cornice, may still have the potential to trigger it.
