Wind slabs may remain reactive to riders.
Recent avalanches on the buried weak layer bring uncertainty. Stick to low angle, supported terrain, free from overhead hazard.
Expect stiffer and deeper deposits of snow on northeast and southeast facing slopes. Watch for steep convex rollovers, ridgetop entrances, and cross loaded features.
A widespread crust with facets is buried 50 to 100 cm deep. While this layer exists on all aspects, it's most likely to be triggered at treeline and above. Wind slabs may step down to this layer, producing large avalanches.
20 cm of recent storm snow has been wind affected in exposed areas. A crust exists below 1250 m, with a reportedly poor bond to the recent storm snow.
A weak layer of facets and a crust is buried 50 to 100 cm deep. This has shown reactivity with the new load from wind and snow.
On Saturday a size 2 rider triggered avalanche occurred on an east facing alpine slope. Notably, the avalanche was triggered as a wind slab and stepped down to the buried weak layer. Photo below.
Large avalanches have been observed in several areas, however the timing of them is uncertain - likely they occurred during the storm. Check out this Hankin MIN, and Blunt MIN for more.
Natural activity may have tapered but the snowpack may remain sensitive to human triggering.
