Kernpunkte

For Monday, expect cool and sunny conditions. You may be able to trigger avalanches at upper elevations in wind-drifted snow. With shallow snow cover, use caution to avoid hitting rocks, logs, and other obstacles.

    Look for slightly drifts and pillows of snow just below leeward sides of ridges. Steer around these features on slopes steeper than 35 degrees. Recent wind slabs may be subtle, so use a pole or probe to feel for stiffer and deeper drifts. 

    There was just enough wind to drift the recent snow and there's still snow available for transport. Near Washington Pass, observers found about a foot of of storm snow at 6,600ft. Wind slabs may be at least that deep, or they may involve only a portion of the new snow. Expect less recent snow t lower elevations and east of the Cacade crest.

Avalanche Discussion

Expect clear skies for much of Monday. The low, weak sun may just be able to warm surfaces on south aspects. Keep an eye out for rollerballs to tell you that the snow is becoming moist and unstable. 

On December 6-8th a storm brought rain transitioning to snow. On Sunday, observers found the foot of snow that accumulated at 6,600ft was well-bonded to the old, moist surface. All snow below was also moist. Take care as you travel - many early-season obstacles, such as trees, rocks, logs, and creeks, are exposed or sometimes barely hidden underneath wind drifted surfaces.
