Regions: Jasper.

If the sun comes out, solar exposed slopes are likely to experience soft slab releases and sloughing.

Avalanche Summary

Confidence

Timing or intensity of solar radiation is uncertain

Avalanche Problems

Persistent Slabs

Recent natural avalanche activity has declined but this snowpack weakness remains very touchy and easily collapses with skier presence.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 4

Wind Slabs

SW winds are creating new wind slabs primarily in the alpine but also in exposed treeline locations. These slabs will be reactive even if they do not have preserved surface hoar beneath them.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3

Storm Slabs

Strong solar radiation is tightening the recent storm snow on solar aspects. Forecast warm temps with continued solar effect is expected. Ice climbers on solar aspects should expect soft slabs, snowballing and sloughing in the PM.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3
