Lo esencial

Weather is promising but you need to make careful evaluation of any slopes and features you venture into!

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–3
    Continued wind loading has produced very touchy wind slabs on lee and cross loaded features.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–3
    Persistent slabs at treeline and sheltered sub-alpine slopes are starting to get overloaded by new snow and wind loading.

Weather Forecast

Cooling temps, dropping freezing levels increased pressure, broken skies, sunshine and new, settling storm snow equal a great day to go riding!

Snowpack Summary

Overnight storm produced variable snowfall amounts through the forecast area. Up to 40cms at Marmot Basin tampering to 12cm at Hilda/Parkers. Touchy conditions still exist in isolated areas at treeline and sub alpine elevations in cross-loaded and lee features. The facet crust layers near the base of the snowpack susceptible to human triggering.

Avalanche Summary

Several avalanches up to sz 2.5 was observed in the field today. Control results at Marmot produced a very large size 3.5 that went full depth wall to wall in Charlie's Bowl!  Several other large natural avalanches were also reported around the ski hill on wind loaded alpine slopes.

Confidence

Due to the quality of field observations
