    We are still finding poor snowpack structure in the Blues, although the likelihood of triggering this layer is low it remains possible. The November/December facets are now rounded, moist, and beginning to bond but are still substantially weaker than the snow above and below them. This creates the recipe for an avalanche. Snowpack tests on 1/31 confirm this.

Avalanche Discussion

Yesterday the Blues finally stayed below freezing and a couple of inches of snow fell.  The new snow fell on a warm wet surface and should bond well. More snow will arrive this evening and the wind will pick up. This will blow the new snow around creating small wind slabs. The crust you will find right under the snow may not be thick enough to protect you from the weak snow below. Triggering the lurking persistent slab avalanche would have devastating consequences. You can see an observation here.
