Avalanche Summary
Storm slabs up to size 2.5 were observed over the weekend in the southwest corner of the region. They formed in response to new snow and wind. Touchy wind slabs to size 1.5 were still remotely triggered on Monday. Patterns in avalanche activity vary greatly across the region due to varying recent snowfall amounts and underlying snowpack structure.
Snowpack Summary
The few reports we've received indicate conditions are highly variable across the region. Approximately 15-30 cm of dense storm snow overlies a variety of crusty old surfaces. Weaknesses buried in the upper snowpack may include hard crusts and/or facet crystals, although not much is known about the reactivity or spatial distribution of these layers. At the base of the snowpack, weak facets may be found. Cornices are large and potentially fragile. Unpredictable, full-depth glide avalanches are also a concern on low elevation slopes with smooth ground cover (grassy slopes, rock slabs, etc.) where large cracks have formed from the snowpack slipping on the ground.
