Avalanche Forecast
Regions: Little Yoho.
Extra caution for ice climbers on Mt Stephen. There have been reports of wind slabs on the approaches to these climbs.
Weather Forecast
Cold weather with flurries is forecast.
Snowpack Summary
The storm snow from last week has settled and tops a 100-150 cm snowpack at tree line. In areas with a thinner snowpack the mid pack facets exist and are quite weak. In these areas the main issue is wind slabs forming a cohesive slab over the facets with potential for larger propagations. Thicker snowpack areas have few weaknesses in the snowpack.
Avalanche Summary
No natural activity was reported or observed in Little Yoho today.

Avalanche Problems
Wind Slabs
Wind slabs exist in alpine and some treeline locations. Watch for these wind slabs as you transition into alpine terrain.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
Persistent Slabs
In areas with less than 150cm of snow the weak mid pack facets from early December remain. This is a concern wherever a cohesive slab of recent snow sits on top of this weakness. Wind loaded areas are the primary concern.
- Watch for whumpfing, hollow sounds, and shooting cracks.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 3
