Avalanche Forecast
Regions: Little Yoho.
Pay attention to new snowfall amounts and how strong the local winds are. Fresh wind slabs can be expected.
Weather Forecast
A weak system tracking in from the west will bring light snowfall to this region overnite and Friday. Accumulations by Saturday may be up to 20 cm. Light to moderate westerly winds are forecasted through to Saturday.
Snowpack Summary
The main issue currently is the Dec.18 layer which is down 20-30 cm and sits on a crust/surface hoar combination at elevations below 2100 meters and on a facet/surface hoar combination at higher elevations. The surface hoar appears to be more prevalent below 2100 meters. Easy to mod shears found on this interface. Wind effect found in the alpine.
Avalanche Summary
No new avalanches have been observed or reported. A large settlement was observed on the Dec 18 surface hoar down 30 cm by a group en route to Isolated Col.

Avalanche Problems
Wind Slabs
Up to 20 cm of fresh snow by Saturday, and light to moderate west winds may create small wind slabs in lee alpine terrain.
Aspects: North, North East, East, South East.
Elevations: Alpine.
Likelihood: Possible - Likely
Expected Size: 1 - 2
Persistent Slabs
The Dec 18 interface is down 20-30 cm is producing easy to moderate results with field tests. This layer may become more reactive with the forecasted additional loading.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2
