Highlights

Seek out wind protected areas to find the great skiing and to avoid those wind slabs.

Keep the deep persistent weak layer in mind, particularly in thinner areas.

    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.
