Snowpack Summary
Up to 20 cm of recent new snow in the past 5 days and strong westerly have winds formed pockets of soft wind slab on lee slopes. A layer of surface hoar is buried 15-20 cm down, and has been reactive with the new snow, mainly causing loose dry sluffing from steeper terrain.A little deeper (between 35 - 50 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. This layer is dormant, and there is not a deep enough overlying slab to create a significant hazard. That said I'd recommend keeping it on the radar, especially as the snow load above increases.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.
