In sintesi

Significant new snow and strong winds have created unstable snow conditions.  Wind-drifted snow will continue to develop into larger slabs on Friday, sensitive to the weight of a skier or rider.  The new snow is sitting on a hard ice crust, the perfect sliding surface.  Avoid all steep terrain, especially in areas that have undergone obvious wind loading.

Avalanche danger has been rated Low, below treeline, due to a lack of snow.

    You could easily trigger a large avalanche by traveling in steep wind-loaded terrain. Cracks that shoot out in front of you, recent avalanches, or actively blowing snow are signs of instability. Reduce your risk by avoiding steep terrain on wind-loaded slopes below ridgelines and features ending in terrain traps.  We've just received significant snowfall, along with strong winds.  These wind slabs may rest over slick crusts formed in mid-December. If an avalanche breaks down to these crusts, they could be larger than expected, potentially greater than 2' deep.  Low-angle routes, wind-scoured slopes, or sheltered terrain often provide safer travel options.

Avalanche Discussion

Extreme Weather:  We just received over 1 foot of new snow in the last 24 hours, accompanied by strong winds.  The Southern Wallowas picked up over 2 feet of snow with 2.5 inches of snow water equivalent.  Winds have not backed off and will continue today.  

Mid-December Crust:  All of the new snow we are receiving is sitting on top of a very firm crust that formed in mid-December.  The new snow will need time to bond to this slick surface.  Triggering an avalanche on this layer could be very consequential.  You would be hard-pressed to self-arrest on this ice layer, whether on your snowmobile, skis, or on foot.   

Travel Advice: Although our enthusiasm for the new snow is high, remember that early-season conditions exist.  Use caution as new snow may be lightly covering rocks, trees, strumps, etc.  If you trigger an avalanche, these obstacles will be trauma boosters.
