    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 yesterday confirm this.

Avalanche Discussion

There has not been more than an hour of below-freezing temperatures in the Blues since 1/13. That is two weeks! The snowpack is wet to moist from the top to the bottom. The November/December facets are now moist and beginning to bond but are still substantially weaker than the snow above and below them. This weak snow continues to produce concerning results in stability tests. You can see an observation here.

The continued warm temps and rain today will not do anything to immediately stabilize this Persistent Slab problem. The snowpack is well set up to take more rain and warm temperatures. However, any time it rains on snow we should pay attention to signs of wet snow avalanche problems and be aware of the weak snowpack structure lurking below.
