Aspects: All aspects.

Elevations: All elevations.

Likelihood

Weak layers deeper in the snowpack may become reactive during strong solar radiation and daytime warming, or if rain showers persist. Large triggers like cornices or loose snow avalanches may propagate slab avalanches on these layers.

Aspects: All aspects.
