A bit of snow combined with wind will keep wind slabs as the main concern at upper elevations.
Recent wind slabs scattered across higher elevation terrain may remain sensitive to human triggering. Slabs may be most reactive where they have formed over a crust.
Avalanche activity over the weekend has been reported as natural and skier triggered wind slab avalanches to size 1 in the alpine and at treeline.
New snow from last week combined with recent wind has formed new wind slabs in exposed alpine and treeline terrain. On solar aspects treeline and below, the new snow overlies a variety of crusts from recent warming, sun, and rain.
We continue to track early January and early December surface hoar and crust layers down 30 to 50 cm and down 80 to 130 cm, respectively. Both are considered unlikely to trigger.
