Regions: Banff Yoho Kootenay.

Scattered flurries with moderate winds should not affect the danger level drastically in the next 2 days. The sun, however, is packing quite a punch on solar aspects at tree-line and below. Pay attention to this warming as you return to the valley.

Avalanche Problems

Persistent Slabs

The Valentines surface hoar down 70-150cm is bonding well to the surfaces above and below. Test results are finding hard to no results on this layer. The chance of triggering will increase in thinner areas, and large avalanches are still possible.

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 and shallow areas are the most likely trigger to produce an avalanche on this layer currently.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3
