Lo esencial

Hazard will increase if forecasted snowfall amounts exceed expectations. Assess your ski line carefully, previously exposed rocks and vegetation will be buried under the new snow.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–2
    Multiple wind slab layers at the top of the snowpack can be triggered and may step down to the deeper instability at the bottom of the snow pack.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    2–3
    Triggering this layer from a shallow area is possible and would have high consequences in terrain features of any size.

Weather Forecast

The forecasted snow fall amounts in the 25 to 35 cms range is desperately needed for the good of our skier souls.

Snowpack Summary

New snow overlies existing wind slabs in the top 40cms. Strong supportive mid pack at TL and above over a very weak faceted base at ground. Below tree line the snow pack has very little support or slab development except in isolated open areas where wind slabs may exist.

Avalanche Summary

Road patrol in the northern end of the forecast area observed a sz 1.5 on a steep sw aspect below tree line.

Confidence

Forecast snowfall amounts are uncertain
