Although natural avalanche activity is tapering off, new snow may still be reactive to human triggering due to a buried weak layer.

Moderate
Avalanche Summary
On Tuesday, avalanche control with explosives produced a few dry loose avalanches, size 1.5, that ran on the weak layer below the storm snow.
We expect new snow will remain reactive to skier traffic on Friday, anywhere winds have formed slabs. Carefully manage sluffing in steep terrain.
Snowpack Summary
Around 30 to 60 cm of storm snow has accumulated recently and may be poorly bonded to underlying layers. The storm snow overlies a hard melt-freeze crust in most areas and a weak layer of facets and/or surface hoar on high north-facing slopes. In wind-exposed terrain, storm snow has been redistributed by moderate to strong southwest wind.
The mid and lower snowpack is well-settled and dense with no other layers of concern.
Weather Summary

Terrain and Travel Advice
- Avoid areas where the snow feels stiff and/or slabby.
- Be aware of the potential for large avalanches due to buried weak layers.
- Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
- Make observations and continually assess conditions as you travel.
Problems
Storm Slabs
30 to 60 cm of recent snow combined with southwest winds have formed slabs at upper elevations. Back off to more conservative terrain if you experience signs of instability like whumphing, shooting cracks and recent avalanches.
Aspects: All aspects.
