Lo esencial

Rugged travel conditions dominate lower elevations while lingering wind slab and cornice problems show that winter is on in the alpine.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–1.5
    If there's any good riding/travel to be had, it's going to be in the alpine. This is also where you're most likely to find lingering wind slabs.

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Cornices have likely formed on alpine ridgelines. Cornices are typically most prone to failure during times of transition. Now is one of those times as we enter a colder period.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No avalanches have been reported. Please submit any observations you have to the Mountain Information Network here.

Snowpack Summary

The warm storm from early last week produced over 200 mm of precipitation that mostly fell as rain. Extreme winds out of the south/southwest likely produced weak cornices along many ridgelines during the storm.Alpine areas near Squamish have the most snow, with around 70 cm of settled snow on the ground. In the alpine, there may be a crust lower in the snowpack. It is thought that there is insufficient snow for avalanches below 1500 m.
