Lo esencial

New snow and strong to extreme winds will keep the avalanche danger elevated. A good time to seek sheltered tree skiing

Problemas de aludes

  • Wind Slabs

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

    Significant snow is available for transport at all elevations, with an additional 30cm in the forecast you can expect wind slabs to be reactive to human triggering.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2

    Freezing levels are expected at about 1700 meters. Places like Parkers ridge will most likely see dry snow. Further down the highway by Weeping wall could see a mix of snow and rain.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible

    When in the Whistlers/Portal and Maligne Regions identify and assess snowpack, especially in thin shallow areas

Weather Forecast

The weather is changing!

Up to 30cm is forecasted over the next 4 days, with Thursday being the snowiest.

Winds are picking up to the 70km/h range from the SW and temperatures slowly dropping to -11 by Thursday.

Snowpack Summary

HST of 10-30cm has settled to about 10cm of snow. Increasing winds forming isolated wind slabs in open TL and ALP. The snowpack shows good bonding in field tests in deeper snowpack areas, shallow snowpack regions such as Whistler/Portal and Bald Hills have bigger a potential for weak layers to wake up and are more complex to assess.

Avalanche Summary

A road patrol south today noted no new avalanches. However with the increasing winds, Snow transport was observed at ridge tops.
