Don't let the new snow draw you into big terrain, the snowpack remains generally shallow and weak.
Summary
Confidence
Avalanche Summary
No recent avalanches have been reported. While avalanche activity has decreased avalanches remain possible which could have particularly high consequences.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
Recent snow continues to accumulate atop a complex, generally weak snowpack.
The mid and lower snowpack contain a number potentially problematic weak layers. Of particular note is a layer of surface hoar down roughly 40 to 80 cm from the surface.
Weak basal facets characterize the lower snowpack, especially in alpine terrain.
Snowpack depths at treeline range from 60 to 140 cm.
Weather Summary
Sunday Night
Mostly cloudy with isolated flurries, west alpine winds 10 to 20 km/h, treeline temperature -12 °C.
Monday
Mix of sun and cloud with no precipitation, southwest alpine winds 10 to 20 km/h, treeline temperature -12 °C.
Tuesday
Mix of sun and snow with up to 5 cm of snow, southwest alpine winds 10 to 30 km/h, treeline temperature -10 °C.
Wednesday
Mix of sun and cloud with trace snow amounts, northwest alpine winds 10 to 30 km/h, treeline temperature -12 °C.

Terrain and Travel Advice
- Avoid areas where the snow feels stiff and/or slabby.
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- Uncertainty is best managed through conservative terrain choices at this time.
Problems
Persistent Slabs
Buried surface hoar is likely becoming harder to trigger. However, consequences remain high if triggered. Small avalanches have potential to step down to deeper layers.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Deep Persistent Slabs
A layer of weak facets near the ground can be triggered by large loads or even by riders in shallow rocky areas.
Aspects: All aspects.
Elevations: Alpine.
