Avalanche Summary
Numerous natural and human triggered avalanches size 1-2 were reported throughout the region on Thursday. A few natural size 2.5 avalanches were also reported on larger terrain features. These avalanches occurred on all aspects and elevations. This trend is expected to continue throughout the weekend as the snow load increases.
Snowpack Summary
A 30-40 cm storm slab overlays a variety of surfaces including large surface hoar, sun crusts, and facets. In recent days, the snow above this layer has settled into a cohesive slab and has become increasingly reactive to human triggers. Expect this slab to be thicker on lee features in the alpine. The mid and lower snowpack are generally well settled and strong.
