Lo esencial

Fresh untracked snow will be tempting this weekend.  Use caution around steeper slopes at tree-line and in the alpine.

    These slabs are found on exposed slopes and produced moderate to hard test results with failures in the facet layer near the bottom of the pack.

  • Persistent Slabs

    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño

    Storm snow has evolved into a persistent slab mainly around treeline and sheltered alpine slopes. Widespread whumphing in open treeline areas.

Weather Forecast

Cloudy conditions with a few flurries but limited accumulation.  Temperatures will continue to moderate with freezing levels approaching 2100m into the weekend.  Ridgeline winds will increase to moderate  from the SW.

Snowpack Summary

Settled storm slab in open treeline areas and windslab on exposed alpine slopes. These slabs are sitting on a couple of crust in the lower third of the snowpack. Failures are occurring in facets above these crusts with moderate test results at treeline and hard results in the alpine.  Whumphing is common at treeline.

Avalanche Summary

No patrol on Maligne or Parkway today.

Confidence

Due to the number of field observations on Saturday
