Avalanche Summary

This avalanche

was reported from the Duffey Lake area on Tuesday. It indicates the nature of the bond between the recent storm snow and old surfaces below may be poor. Most other recent reports from this region have been of small loose snow avalanches.

Snowpack Summary

Light amounts of new snow have been redistributed by southwesterly and northerly winds, potentially creating some unusual wind slabs, including on south-facing slopes. Beneath this recent snow you may find hard wind-affected snow at higher elevations, soft and faceted snow in shaded and sheltered areas, and melt-freeze crusts on southerly slopes. The middle and lower snowpack is generally well-settled.

Avalanche Problems

Wind Slabs

Winds shifted to the north at the tail end of the storm, potentially building wind slabs on south-facing slopes in exposed areas. Watch also for the potential for slab avalanches on sun-affected slopes.

Use caution in lee areas. Recent wind loading have created wind slabs.Avoid travelling in areas that have been reverse loaded by winds.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
