Avalanche Summary
No new avalanches were reported on Monday but observations were limited due to cold temperatures. We expect new snow will remain reactive to skier traffic on Wednesday, anywhere switching winds have formed slabs. Carefully manage sluffing in steep terrain.
On Sunday, reports from the area noted significant sluffing in steep terrain.
Snowpack Summary
Storm snow totals range from 15 to 35 cm, with deeper deposits on north and east facing slopes from wind loading during the storm.
The new snow is 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 fresh reactive wind slabs in isolated lee terrain features. Windslab will be primed for human triggering. Minimize exposure during periods of heavy loading from wind.
