Comments

We observed several size 1-1.5 storm slab avalanches both Sc and Sa (from multiple groups) in the tryst lake chutes today. 20-40cm deep with the widest propagation around 25m in some of the more connected features. Bed surfaces varied from faceted snow, buried wind board, and skier compacted snow. Overall the new storm snow is bonding poorly to previous layers, and is slabbing up easily.
