Regions: Little Yoho.

By Tues, accumulations of up to 20cm can be expected in the alpine. Currently this is not enough to alter the danger ratings. Today a skier remote size 2 was reported on the Crowfoot Glacier on a N aspect. There is still potential out there.

Avalanche Problems

Persistent Slabs

The Valentines surface hoar is 70-150cm down. Avalanche control was still producing the odd slide on this layer today. Typically from steep terrain with a shallow snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3

Deep Persistent Slabs

Although difficult to initiate, it is still possible to trigger a deep persistent slab. Heavy loads in steep terrain with shallow snow are the most likely areas to produce an avalanche on this layer.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3
