Avalanche Forecast
Regions: Little Yoho.
Forecasters are still trying to determine exactly where the surface hoar is located. Typically it can be found between 1700m and 2150m in sheltered locations.
Weather Forecast
We expect to see a few cm's of snow and increasing SW winds into Sunday. Temperatures will be slightly warmer ranging from -2 to -10'C.
Snowpack Summary
In sheltered terrain between 1700m 2150m, a 30-40cm soft slab sits over the December 3rd surface hoar. This layer continues to produce whumphs and easy shears in many locations. No other significant shears have been observed. In the alpine isolated wind slabs exist in immediate lee areas.
Avalanche Summary
No new avalanches observed today in our forecast area.

Avalanche Problems
Persistent Slabs
A 30-40cm soft slab sits over the Dec 3 surface hoar in many sheltered location between 1700m and 2150m. Continue to treat all steep open slopes below tree line with suspicion until you can rule out this weak layer.
- Avoid open slopes and convex rolls at and below treeline where buried surface hoar may be preserved.
Aspects: North, North East, East, South East, South, South West.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 2
Wind Slabs
With increasing winds Saturday night, continue to watch for wind slabs in typically suspicious areas: leeward and cross loaded slopes or slopes near ridge crests.
- Use caution in lee areas. Recent wind loading have created wind slabs.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2
