In sintesi

Human-triggered avalanches are possible today. Look out for wind affected snow in steep terrain and continue to evaluate the snowpack for weak layers 2-4 feet from the surface.  While the chance for triggering a deeper weak layer has diminished, it is still possible especially on steep, shady slopes over 35 degrees in steepness.

    Weak snow from January lies 2-3 feet below  the snow's surface. Though this drought layer has gained strength with time, triggering a large and widely propagating avalanche remains possible, especially in very steep terrain above about 8,000'. This problem continues to deserve respect, especially in high consequence terrain and places where the slab may be thin enough for the weight of a person or sled to hit the weak layer. There may not be a warning sign bfore triggering this layer as the slab above has grown stiff and stubborn.

    Cornice Fall: Large triggers such as a falling cornice could trigger a larger avalanche. While unlikely, it's a good idea to give cornices some space.

    Snow which fell two days ago, combined with small amounts of new snow yesterday and today has formed drifts  in wind exposed areas. These slabs may be up to a foot deep  and are likely to be soft and may be sensitive to triggering. Wind sculpted surfaces and shooting cracks signal danger.

Avalanche Discussion

A series of small storms with moderate winds over the past several days have produced fresh slabs of wind-drifted snow across upper-elevation terrain. In many areas these slabs are forming on a weak interface, creating the potential for human-triggered avalanches up to about two feet deep. Warming temperatures have helped to make this snow upside-down. 

A deeper, more persistent problem remains in parts of the snowpack, especially on shaded slopes.. While activity on this layer has been inconsistent, it still has the potential to produce larger, more destructive avalanches if triggered from shallow areas or near rocky features. Weak layers like this can linger long after storms have passed and can surprise travelers who assume the snowpack has stabilized.

Travelers today should watch for signs of instability such as recent avalanche activity, cracking in the snow surface, or hollow-feeling wind slabs. If you encounter these red flags, avoid steep, wind-loaded slopes and move to lower-angle terrain where you’ll find softer snow without wind-affect.

Thanks for submitting your observations. Please continue to share even when the weather and snow is uninspiring. Observations remain helpful even in the absence of avalanches!
