Avalanche Summary
No new avalanches were reported on Wednesday.
Natural and human-triggered avalanches are likely on Friday.
Snowpack Summary
15 to 25 cm of snow is forecast by Friday afternoon. The new snow will likely have a poor bond to the old snow surfaces. These consist of a thick melt-freeze crust on sun-exposed slopes, large surface hoar and/or facets on shaded slopes, and wind-affected surfaces in exposed terrain at ridgelines.
The mid and lower snowpack are generally strong and well-settled. Treeline snowpack depths average 100-150 cm.

Terrain and Travel Advice
- Storm slab size and sensitivity to triggering will likely increase through the day.
- Avoid freshly wind-loaded terrain features.
- Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
Problems
Storm Slabs
The new snow will have a poor bond to the underlying snow surfaces and reactive storm slabs may build through the day. Northeast aspects will likely see deeper slabs with wind loading.
Aspects: All aspects.
