While the likelihood of skier triggering is relatively low we have observed several large, high consequence avalanches on steep unsupported alpine slopes. Don't let the sunny skies cloud your judgement.

Confidence

The weather pattern is stable

Problems

Deep Persistent Slabs

Warm temperatures and solar radiation have lead to the re-awakening of two instabilities. Recent wind slabs and the early season basal facet layer have produced a few large, high consequence avalanches on steep unsupported alpine features.

Aspects: North, North East.

Elevations: Alpine.

Likelihood

Possible

Expected Size

2 - 3

Wind Slabs

The majority of the previous windslabs are bonding well, but there is still the potential to trigger isolated slabs in steep, wind loaded areas in the alpine.

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

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 3
