Avalanche Forecast
Regions: Akamina, Flathead, Lizard, Lizard-Flathead.
Continue to make conservative terrain choices as recent snow may still need time to bond to the faceted surfaces underneath.
Confidence
Moderate
Avalanche Summary
Numerous size 1 storm slab avalanches were skier-triggered over the weekend, on various aspects and elevations.
Explosive control work on Sunday produced two size 2 avalanches storm slab avalanches in steep, northwest-facing alpine terrain.
Snowpack Summary
Recent snow has been redistributed by primarily southwest winds in exposed alpine terrain. Below the new snow are old faceted surfaces formed during the extreme cold earlier in the month.
A weak layer of facets above a melt-freeze crust is found down 60 to 100 cm.
The mid and lower snowpack is generally well bonded with a series of crusts and faceted snow.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Be carefull around freshly wind loaded features.
- Closely monitor how the new snow is bonding to the old surface.
Avalanche Problems
Storm Slabs
Recent snowfall has buried a layer of old firm, faceted surfaces that may not be bonding to the new snow above. Slabs may be particularly reactive in exposed treeline and alpine terrain where recent wind loading has occurred.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2
