Regions: Little Yoho.

As we head into a week of very cold temps the danger rating is expected to remain as is. Watch for increasing wind creating fresh slabs at high elevations. Be mindful of the basal weaknesses when committing to larger terrain features.

Avalanche Problems

Wind Slabs

Surprisingly little wind effect in the Emerald Lake region today. However, the 20cm low density storm snow is available for transport when the wind decides to pick up. Be watchful at a local level for increasing wind and associated slabs.

Aspects: North, North East, East, South East, South, South West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

A well settled midpack overrides a weaker facetted base. This weak base is found most places except the west side of the divide. Beware of steep shallow snowpack areas (where the likelihood of triggering this basal layer is highest).

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3
