Recent Avalanches, Heavy Snowfall, Wind Loading, Poor Snowpack Structure
Red Flags Comment
<p>Had a lot of them today. Very warm start, rain, then high winds/transport, high PI rates. Large natural avalanches, cornices growing and sensitive</p>

Full depth natural avalanches in the first two pictures. The cornices are getting fat, and they are cracking back a little ways. Watch out while traveling on ridge lines, know where solid ground is.

Instability Comment
<p>As seen in the full depth natural avalanches this is a real concern, and the most unmanageable or fatal of the problems. Persistent slab avalanches are also a main concern seeing the mid-pack weak layer being triggered by the sensitive storm slab stepping down. This layer is just waiting for a trigger, even in areas where the basal facets/deep slab problem doesn't exist.</p> <p>With the shifting winds and all the snow transport there will definitely be some wind slabs of varying thicknesses out there.</p>

Snow at 8,700 HS 38", HN24 6", HST 6" with 12% SWE at 11:00.  Observed a 0.5cm rain crust that disappeared right about 9,000'.  By 14:30 additional 3" at 8,700" of light density snow.
