Lo esencial

Good skiing can be found in sheltered areas. Approach lee features and gullies with caution as they are loaded.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–2.5

    Hard windslabs are widespread in alpine areas and even down into treeline. Listen for that drummy or hollow feel as an indication to be extra careful.    

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1.5–3

    Exposed, west facing alpine slopes have been stripped bare. This means the Nov 5 layer will be buried deeper than expected in some areas. In turn, this means that deeper layer will be more stressed with the additional load.

Weather Forecast

Avalanche Summary

No new avalanches observed along the Spray road.

Snowpack Summary

Evidence of widespread wind slabs at tree line and above. The lee features and cross loaded gullies are especially looking fat from last week's wind events. The November crust is down 40-100cm and is producing anywhere from moderate to no results.  

Terrain and Travel

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Watch for areas of hard wind slab on alpine features.
