Points saillants

Daily flurries are helping to refresh the ski quality. North facing, sheltered areas are the best bet for good turns.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2.5

    The widespread wind slabs are now hidden under 10cm of fresh low density snow. These are primarily a concern in steep, convex and unsupported terrain. Thin areas may also be trigger points. Expect to find fresh wind slabs on E through S aspects. 

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely
    Taille
    1.5–3

    This problem is still difficult to trigger, but snowpack stability tests today indicate a failure in the basal facets. Any resulting avalanche will be large and destructive.

Weather Forecast

Remember yesterday's weather? Well, tomorrow will be like that. Cloudy skies with flurries, daytime high of -6 and light, but gusty winds. 

Avalanche Summary

Nothing new today.

Snowpack Summary

Convective flurried continue to roll through, but accumulation is minimal given the sun peaking through the clouds. The windslabs continue to pile up on top of themselves with continued SW winds. There may be pockets of new slabs that are slow to bond, but generally they seem to be quickly settling out and staying where they are supposed to. We do have a couple of crusts to deal with on south aspects and lower elevation areas.

Terrain and Travel

  • Avoid convexities, steep unsupported terrain and rocky outcroppings.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
  • Watch for areas of hard wind slab on alpine features.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
