The recent snow may be touchy to human traffic. Tread cautiously and keep a conservative mindset if you notice slab properties or see signs of snow instability.

Avalanche Summary

One small storm slab avalanche was triggered with an explosive on Saturday. Otherwise, no new avalanches were observed.

Snowpack Summary

Around 10 to 20 cm of recent snow fell with strong southwest winds. This snow fell onto a sun crust on south aspects and feathery surface hoar in sheltered and shaded areas at all elevation bands. The new snow may not bond well to these layers, particularly once the new snow gains slab properties.Below this, the snowpack is generally well-settled.

Avalanche Problems

Storm Slabs

The recent storm snow may not bond well to underlying layers. Treating this snow with caution is advised. The deepest and touchiest snow may be in lee terrain features due to strong southwest winds.
Make observations and assess conditions continually as you travel.Watch for signs of instability such as whumpfing, cracking, or recent avalanches.Be careful with wind-loaded pockets, especially near ridge crests and roll-overs.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2
