Snowpack Summary
Regionally variable HST values up to 35cm over the past 4 days atop a solid mid-pack. Alpine and exposed TL scoured and sculpted by steady SW winds. Hard windslab present in lee features. Feb 13 interface down 20-50, present as MFc on solar aspects or DF interface on polar aspects with resistant reactivity through the region.
Avalanche Summary
Tuesdays avalanche control highway 93 south produced up to size 1.5 wind slab averaging 30cm deep. A few size 1.5 dry loose observed in steep alpine terrain. Ski cut on an steep, unsupported feature in the Maligne range produced a size 2 on a hard wind slab.
Confidence
Avalanche Problems
Wind Slabs
Sculpted terrain features widespread in the Alpine and Treeline.
- Use caution in lee areas. Recent wind loading have created wind slabs.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
Loose Dry
With up to 35cm of new snow, loose new snow could be an issue for ice climbers in tight gullies or steep cliffs above.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
- Be careful of loose dry power sluffing in steep terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 2
