Avalanche Forecast
Regions: Little Yoho.
Conditions are highly variable right now, and the danger ratings represent the highest danger rating for the day. Avalanche danger is lower in the morning when the snow surface is frozen, and before the air temperatures warm up. Start early.
Weather Forecast
Clearing through the day on Wednesday, with sun patches appearing in the afternoon. Expect a high of 0 degrees at treeline, and lows of -10 early in the morning. Trace amounts of snow expected overnight for Wednesday.
Snowpack Summary
The snowpack is a real mixed bag right now: totally dependent on aspect and elevation. At treeline and above, 5-10 cm of new snow overlies a strong melt-freeze crusts to ridge top on solar aspects, and 2000m on north aspects. Below treeline the snowpack becomes wet through the day. The snowpack has not converted to spring conditions yet.
Avalanche Summary
No new avalanches reported or observed today.

Avalanche Problems
Loose Wet
Afternoon warming will create loose wet problems at low elevations and on S and W facing terrain at higher elevations.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2
Cornices
Cornices continue to fail. Minimize your time underneath these and remember that a cornice failure could also trigger the deep persistent slab on the basal facets.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
Likelihood: Possible - Likely
Expected Size: 1 - 3
Persistent Slabs
The snowpack is gaining strength, however the facets deeper in the snowpack remain a concern in thin alpine areas and where a cornice could trigger the slope.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 2 - 4
