Lo esencial

Be cautious and assess each slope you ski. The Icefields zone received 60cm of snow in a very short period.

All signs are pointing toward an improving hazard but most slopes are untested.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3

    New and developing wind slabs in the forecast region. Slab sensitivity will vary; with potentially wide variations over a small area. Assess each slope independently.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1.5–3.5

    Wind loading and cornice development could trigger large avalanches running far and fast.

Weather Forecast

Status Quo for weather in the forecast region expected over the weekend. So what does that mean? Seasonal temperatures (-15 to -5), cooling with elevation. Light to moderate SW winds. Scattered clouds in the morning, increasing with some light convention in the afternoon.

Snowpack Summary

Up to 50 cm of snow fell during last weeks storm in the forecast region. Previous mid-pack bridging over deeper instabilities is supporting the new load over the basal facets and depth hoar. This new load and bridging has still not been significantly field tested, treat the snowpack with caution.

Avalanche Summary

Good visibility for southern road patrol showed limited activity. Notably, large windslab avalanches (sz 2.5 - 3.0) were noted on NE aspects from steep, rocky features on both Mts. Athabasca and Cromwell in the Icefields Region.
