Avalanche Forecast
Regions: Little Yoho.
Despite the lack of recent natural activity forecasters have low confidence in the snowpack. Conservative terrain choices are still advised. BW
Weather Forecast
Isolated flurries expected for Friday and mixed sun and cloud for Saturday. Light winds and a cooling trend forecast through to Saturday. Freezing levels at valley bottom.
Snowpack Summary
30-50 cm of storm snow throughout the region since March 15th which is starting to settle and bond to previous surfaces. There is some wind slabs in specific lee terrain in the alpine. The Feb.10th facet layer is down 80-120cm and is still showing easy to moderate test results in thinner snowpack areas, and harder results in deeper snowpack areas.
Avalanche Summary
No avalanches were observed or reported today. A large sz.3 cornice triggered avalanche was reported on Tuesday in the Sunshine back country. This failed on the Feb.10 interface and stepped to ground in thin areas. We have seen sporadic natural activity like this over the last week.

Avalanche Problems
Persistent Slabs
Feb 10 shears tightening up in deep snow pack areas west of the divide. In shallower snowpack areas this interface still producing whoomphing and easy to moderate shears.
- Avoid areas with overhead hazard.
- Use conservative route selection, choose moderate angled and supported terrain with low consequence.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible - Likely
Expected Size: 2 - 3
Wind Slabs
- Be cautious as you transition into wind affected terrain.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
