Points saillants

In this region, triggering the deep basal weak layer is unlikely but not impossible. Uncertainty is limited to steep alpine terrain with a thin to thick snowpack.

    Basal facets or a facet–crust combination persist near the ground. Triggering is unlikely, but this type of deep persistent layer is inherently uncertain and may still be triggered in isolated, steep terrain with a thin-to-thick snowpack.

Avalanche Summary

No new avalanches observed or reported in this region on Sunday.

Snowpack Summary

Extensive wind effect exists in the alpine, with some surface faceting helping to break down crusts and create softer skiing. In protected treeline and below-treeline terrain, widespread surface hoar was buried by a few centimetres on Saturday. A deeper surface hoar layer lies 50–60 cm down, but there have been no recent avalanches. Basal crust and/or facets exist in thin snowpack areas, but overall, this year's deeper snowpack is stronger than usual.

Weather Summary

Little change in the forecast for the next few days. We will see a slight, gradual warming of temperatures, with little to no precipitation and moderate westerly ridge winds. In the long-range forecast, some snow accumulation is expected starting Friday.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
