Kernpunkte

Large natural avalanche activity is tapering off, but the Deep Persistent avalanche problem could still be primed for human triggering.

Some excellent skiing is being found in areas that are sheltered from the ongoing winds.

    Ongoing moderate to strong transport from the SW is redistributing snow into lee features.

    There have been numerous large avalanches up to size 4 in Jasper this past week. This problem encompasses multiple weak layers of facets, crusts, and basal facets from November and December.

Confidence

Moderate

  • Uncertainty is due to the fact that deep persistent slabs are particularly difficult to forecast.

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
