Avalanche Summary

Over the past few days, a few small (size 1) loose and slab avalanches were triggered naturally and by skiers within the recent storm snow.

Snowpack Summary

Around 10 to 15 cm of recent snow sits on a variety of surfaces, including wind-affected snow in exposed terrain at higher elevations, soft and faceted snow in shaded and sheltered areas, and a melt-freeze crust on southerly slopes. The middle and lower snowpack is generally well-settled.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
