Avalanche Summary
Recent reports indicate a few natural avalanches running to 2 in the past 3 days. These were reported as possible windslab releases at the treeline elevation on northerly aspects.
Snowpack Summary
Up to 25 cm of recent new snow in the past 5 days and moderate to strong west and northwest winds have formed pockets of wind slab on lee slopes. A layer of surface hoar is buried 20-25 cm down, and has been reactive with the new snow, soft slab and loose dry avalanches in steeper terrain.A little deeper (between 40 - 60 cm below the surface) you may find a weak layer of surface hoar on sheltered slopes or a crust/facet combo on steep solar aspects. As the load gradually increase and stiffens over top of this layer, it may well become more reactive.In general, snowpack depths are below seasonal average with many slopes below treeline still reported to be below threshold for avalanche activity. A deeper snowpack is likely in the northern part of the region.
