Avalanche Forecast
Regions: Little Yoho.
Watch for windslabs over rotten snow.
Weather Forecast
Cold weather with flurries is forecast. A new low over the Charlottes may bring snow to the area by Monday. The weak surface facets will not be able to withstand any loading in the short term.
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.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
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.
Likelihood: Unlikely - 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.
Likelihood: Unlikely - Possible
Expected Size: 1 - 3
Loose Dry
Loose snow avalanches in gullied terrain can have larger consequences.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2
