Small wind slabs in isolated locations on steep terrain may remain reactive to human triggers.
The crust formed by the rain event last week has created a significant falling hazard in steep terrain.

Avalanche Summary

Snowpack Summary
5-15 cm of wind-pressed snow overlies a thick (10-15 cm) rain crust that extends to mountain tops. This crust has created challenging travel conditions and a "slide-for-life" hazard on steep slopes.
Small wind slabs may be found on lee features in the alpine.Â
The weak layers in the snowpack (such as the crust or surface hoar layers down around 100 cm) are unlikely to human trigger in areas where a hard surface crust is present. If the surface crust is warmed up and breaks down, triggering persistent slab avalanches becomes more likely.
However, cornices overhead are a primary concern during sunny, warm, or windy conditions. Cornice failures may trigger very large persistent slab avalanches that would otherwise be difficult to human trigger.
Terrain and Travel
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
- Avoid exposure to slopes that have cornices overhead.
