Avalanche Forecast
Regions: Little Yoho.
We are experiencing incremental loading as the new snow and wind build on top of facets. Loose snow facet-lanches are running far, fast and powerfully.
Weather Forecast
Light accumulations will continue. Up to 15cm of snow can be expected between now and the end of Friday. The wind is expected to pick up on Thursday midday (Moderate West). All of these small weather inputs are contributing to incremental loading.
Snowpack Summary
15-25cm of recent storm snow from the past week has been blown into windslabs in high alpine areas. Meanwhile, the overall snowpack continues to gradually become weaker from the facetting process, and in some areas the upper snowpack is comprised entirely of facets with no cohesion.
Avalanche Summary
Forecasters were able to ski cut a size 1.5 windslab that entrained facets and ran for 700m.

Avalanche Problems
Loose Dry
New snow and surface facets will sluff easily in steep terrain (40+ degrees). These sluffs may have high consequence for skiers or climbers in large or confined terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 2
Wind Slabs
The new snow over the last week has been adding up in increments, compounded by moderate west wind to create localized windslabs.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 2
