Conditions remain largely unchanged with Low danger and stable snow almost everywhere, except in the occasional shallow snow spot where we have seen two skier-triggered avalanches occur over the past week - both in Extreme terrain with rock bands and wind-drifted snow creating variability in the snow depth.

Confidence

Avalanche Summary

No new avalanches have been observed or reported on Monday.

Snowpack Summary

Extensive wind effect exists in the alpine, with some surface faceting helping to break down crusts and create softer skiing. In sheltered areas at treeline and below, widespread surface hoar was buried by a few centimetres on Saturday and is now the Jan 24 layer. 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.

Problems

Deep Persistent Slabs

Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
