It will likely still be warm with a mix of sun and cloud on Thursday. If the sun stays out for an extended time think about an increase in the likelihood of loose wet avalanches running in steep terrain facing the sun.
Summary
Confidence
Avalanche Summary
There is no avalanche activity to report in the last few days.
Snowpack Summary
There is likely a surface crust or moist snow on all aspects except north. On high northerly slopes, new snow from last week may overlie facets and surface hoar to mountain tops.
The middle of the snowpack is generally well-settled and strong.
A weak layer of large facets is found near the base of the snowpack. This layer is still a concern in shallow snowpack areas.
Weather Summary

Terrain and Travel Advice
- As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
Problems
Deep Persistent Slabs
A weak layer of facets exists near the base of the snowpack. The likelihood of human triggering is low given the layer's depth.
Aspects: All aspects.
