Avalanche Forecast
Regions: Little Yoho.
Considerably more snow fell in the Yoho area during this storm cycle. Avoid large objectives for a while.
Ice climbers should avoid overhead hazard and tight gullies.
Weather Forecast
Moderate snow and cool temperatures are forecast.
Snowpack Summary
Up to 50 cm of new snow has fallen at treeline during this storm cycle. The new snow is not bonding well to the old snow giving easy test results at the interface. Moderate winds have created windslabs in lee areas. Deeper facetted areas may fail in a larger fashion. Below treeline, facets can be bottomless and pose a hazard in gullied terrain.
Avalanche Summary
No new activity reported today. Visibility was poor.

Avalanche Problems
Storm Slabs
There has been 25 cm of new snow at treeline and up to 50cm in alpine. Some cracking in storm snow was observed on Tuesday. Additional snow is expected. This storm snow will take several days to settle out.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 3
Wind Slabs
Recent moderate to strong SW winds have redistributed storm snow creating wind slabs in alpine and some treeline locations.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2
Loose Dry
Recent storm snow is sluffing out of steep terrain. Ice climbers in particular should be paying attention to this problem.
- Choose ice climbs that are not exposed to avalanches from above.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2
