Moderate
Avalanche Summary
No new avalanches were reported on Monday and Tuesday but observations were limited due to cold temperatures.
We expect that human triggered wind slab avalanches will be possible on Thursday.
Snowpack Summary
Storm snow totals range from 15 to 35 cm, with deeper deposits in wind-loaded areas. Wind has varied in direction, so expect to find wind slabs on all aspects.
The new snow may be bonding poorly to old surfaces, which include melt-freeze crusts on sun-exposed slopes, surface hoar or facets on shaded slopes, and wind-affected snow at higher elevations.
The lower snowpack is strong and bonded.

Terrain and Travel Advice
- Closely monitor how the new snow is bonding to the old surface.
- 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
Wind Slabs
Variable alpine winds are developing wind slabs in isolated lee terrain features. Wind slab will be primed for human triggering. Minimize exposure during periods of heavy loading from wind.
Aspects: All aspects.
