Avalanche Summary
No new avalanches reported or observed today.
Snowpack Summary
4cm of moist snow fell throughout the day now just covering the variety of surfaces that include Sun crusts on solar aspects (S-W) and facets and wind scoured surfaces elsewhere. Generally a weak snowpack. Natural avalanches are possible and the consequences would be significant because any trigger would likely make the entire snowpack slide.

Terrain and Travel Advice
- Be aware of the potential for surprisingly large avalanches due to deeply buried weak layers.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
