Natural avalanche activity has tapered, but human-triggered avalanches are possible.
Continually assess as you travel, back off if there are signs of instability.
Large overhanging cornices remain possible to trigger naturally, but are less likely as temperatures cool. Give slopes threatened by cornices a wide berth and keep well back from ridges, human triggering is possible.
Saturated surface layers can be found even at upper elevations. Natural wet loose avalanches have tapered and are unlikely where a surface crust has formed. Human-triggered avalanches remain possible where no crust is present.
During the storm, Several size 2 wet loose avalanches were reported.
Going forward, wet loose avalanche activity will taper and may be unreactive where a surface crust is forming. Watch for moist or wet snow as you travel.
A significant rain and warming event has saturated the upper snowpack to ridge-top.
Clear overnight skies have likely started to form a surface crust that may break down during the day. Below this the snowpack remains moist.
The mid-December crust is 100 to 250 cm deep. This crust is 30 cm thick and well-bonded to the snow above.
