    Fresh wind slabs on the downwind side of ridge crests and terrain features have formed. Expect to find these pillows of wind-transported snow in unusual places thanks to recent northerly winds.

Avalanche Summary

Recent reports indicate avalanche activity as thin windslabs in the alpine to size 1 and loose now sluffing in steep terrain to size 1.

Snowpack Summary

Around 30cm of faceted powder overlies the facets and surface hoar that was buried last weekend. Variable light to moderate winds have loaded immediate leeward features with touchy wind slabs. A widespread crust that was buried in November is typically down 80-100cm. Recent tests show this persistent weakness has the propensity to propagate large avalanches if triggered, from thin rocky areas, for instance.
