Snowpack Summary

Total snowpack depths are likely around 150 cm at treeline, and 2 m or more at higher elevations. The new snow continues to build weak storm slabs with particularly deep and touchy wind slabs on leeward slopes in exposed areas. However, warm temperatures are promoting rapid settlement and strengthening.

Problems
