Moderate
Avalanche Summary
We are still awaiting observations from the storm. We expect avalanches on Friday were small but easily triggered by riders. Avalanche size and sensitivity will likely increase as snowfall continues overnight.
Snowpack Summary
Light snowfall continues. 15 to 30 cm of new snow has accumulated since Thursday night. Near ridgetops, moderate southwest wind has loaded new snow into leeward terrain features. The new snow is not expected to bond well to underlying surfaces including a crust, facets and/or surface hoar.
The mid and lower snowpack is well-settled and dense with no layers of concern.

Terrain and Travel Advice
- Watch for signs of slab formation throughout the day.
- Expect slab conditions to change drastically as you move into wind-exposed terrain.
- As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
Problems
Storm Slabs
As new snow accumulates, storm slabs may form, especially in wind-affected areas. Slabs will likely be reactive as they are not expected to bond well to underlying surfaces.
Aspects: All aspects.
Elevations: All elevations.

Expected Size
Loose Dry
Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
