Avalanche Summary

Natural and artificially triggered avalanche activity was reported from across the region on Tuesday. Cornices remain large and fragile. They have been failing naturally and would likely collapse under the weight of a person.

Snowpack Summary

New snow and strong winds are going to  build fresh soft slabs overnight on Tuesday. The upper snow pack sits on a widespread crust at treeline and below as well as up to an elevation of about 2200m on aspects that see direct sun. In isolated sheltered north aspects it may sit on pockets of surface hoar or facets. Cornices are large and weak. The midpack is generally well settled.
