Avalanche Summary
Small soft slabs and loose dry avalanches have been failing naturally and with skier traffic.
Snowpack Summary
Around 25cm of new snow overlies a medley of surfaces including hard wind slabs, thin and thick crusts and large surface hoar crystals which can be found in sheltered areas below treeline. Recent winds have shifted snow into soft and hard slabs on lee slopes. A surface hoar layer buried down 40-80 cm seems to be gaining strength. Near the base of the snowpack, a crust/facet layer exists, which is now unlikely to be triggered, except perhaps by heavy triggers in unsupported, shallow, rocky terrain where more faceting has taken place.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
