Points saillants

Skip work and get out and get some turns or swing the tools folks, winter's almost over. You're going to miss it when it's gone!

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2
    Quite variable but generally well bonded soft slabs and windslabs in lee features in the alpine and at treeline. Not likely to see much in natural activity but may be possible to trigger underfoot.
  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    2–3
    Large cornices or surface avalanches are the likely trigger.

Weather Forecast

The weather pattern will remain stable for the day Thursday; full cloud cover, moderate SE-ly winds with some local variation, small inputs of snow and freezing levels are to remain below 2000ms. Mild sub-zero temperatures and brisk winds should keep the snow surface dry and anything left available to transport will continue to load lee features.

Snowpack Summary

Until we have a significant change in snow or sun there will be little modification to the danger. Local variations though forecast area (near townsite) with significant rising daytime temps, freezing levels or snow inputs will weaken the bond on the storm slab at the surface on steeper slopes, especially on solar aspects or lower elevations.
