Avalanche Summary
Natural and artificially triggered avalanche activity up to size 2.5 was reported from across the region on Saturday. Cornices remain large and fragile. They have been failing naturally and would likely collapse under the weight of a person.
Snowpack Summary
Up to 75cm of recent storm snow is being reported in sheltered areas with up to 150cm in wind loaded areas. Weaknesses within or at the base of the new storm snow may need a couple days to settle and strengthen. Southerly winds have created very deep and dense slabs in lee terrain, probably well below ridge crests, while scouring windward slopes. Cornices are large and fragile. The mid and lower snowpack are strong and well-settled.
