    Expect to find new slabs from recent snowfall. Expect thicker and more reactive slabs in lee features due to strong south to easterly winds.

    Recent rainfall and warm temperatures at low elevations have weakened the snow surface. Watch out for steep and gullied terrain, where small avalanches can build and have severe consequences.

Avalanche Summary

Recently formed slab avalanches were reactive to skier traffic on Friday. See this MIN report for more info and photos. Small loose wet avalanches were also triggered by skiers and naturally.

Snowpack Summary

Around 20 to 30 cm of storm snow fell with strong southeast winds, redistributing it into lee features in exposed terrain. The new snow overlies a thin crust and settled snow from last weekend. A 5 cm thick crust is found around 50 cm deep on all aspects and elevations, except above 1900 m on north slopes.The snowpack below this is generally well-settled and strong.
