Lo esencial

Warm temperatures and solar input will drive the hazard this weekend. Pay close attention to sun affected slopes

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    Recent changes in wind direction will mean both soft and hard wind slabs on most aspects, pay close attention as you transition into new terrain, especially at tree line and above.

  • Loose Dry

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–3
    Warm upper elevation temperatures combined with strong solar effect have set the stage for loose sluffs out of steep terrain. These could be big enough to injure or bury a rider.

Weather Forecast

A modified, dry arctic air mass remains over the much of the province. Expect valley fog in the morning at lower elevations and sunshine in the alpine for most of the interior of BC. Moderate temperatures aloft, with above freezing layers of warm air, will pass through the Province during the weekend.  For more in-depth weather information visit: https://avalanche.ca/weather

Avalanche Summary

Several small loose dry avalanches, small soft slab avalanches, and 1 large glide-crack release have been reported over the last couple of days. Continued warming in the alpine combined with sunny conditions could result in loose natural avalanches from steep south-facing slopes. Recent storm snow will begin to show slab properties as it settles with the warm temperatures.

Confidence

Moderate - Timing or intensity of solar radiation is uncertain

Snowpack Summary

20-40 cm of settling low density snow overlies a generally strong snowpack. You may encounter wind slabs which are sensitive to the weight of a person near ridge tops. Recent storm snow may sluff in steep terrain, especially with a touch of sun. The lower snowpack is reportedly well settled. The early December weak layer (about 80-150 cm down) is spotty in distribution, but where it does exist still gives hard, sudden results, meaning it is unlikely to be triggered, but could produce a very large avalanche.
