For the best riding seek out sheltered slopes where the recent storm snow hasn't been wind-affected.
Watch for changes in the upper snowpack if the wind picks up or the sun comes out.
Watch for pockets of cohesive wind slabs on the lee side of ridges or ribs. If northerly outflow winds pick up on Monday, fresh wind slabs may form anywhere there is powdery, dry snow available to be transported.
With the sugary, faceted, and weak snowpack wind slabs could step down to the middle of the snowpack, resulting in larger than expected avalanches.
No new avalanche reports. Keep sharing your observations via the MIN; it helps strengthen our information gathering.
In deeper zones at 1900 m the snowpack is around 100-130 cm, which is low for middle of December, and it has a weak structure.
Surface: Boot top powder in deep areas. Same old crusts, facets, and rocks on wind scoured slopes. Wind slab pockets lee of ridges.Upper-pack: Below the fresh snow is well developed surface hoar in sheltered areas. The upper part of the snow pack is generally low density and faceting (aka weak).Mid-pack: maybe a crust or two, with a layer of soft facets above. This is likely the primary weak layer.Lower-pack: facets and depth hoar (aka not strong).
