In sintesi

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

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    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 pockets of wind slab that may remain sensitive to human triggering.

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Cornices have likely formed along 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 storm from early last week produced ample precipitation, however it mostly fell as rain. Extreme out of the south and southwest likely produced widespread cornices and wind slabs in lee terrain during the storm.A MIN from Friday suggests that it's skiable from about 1600 metres on up. Between 1600 and 2000 m there is 5 to 10 cm of low density snow over a 5 cm breakable crust. Above 2000m is reportedly skiing well and alpine snowpack depths are approaching 175 cm. Near the ground there is a crust/facet interface, but little is known about the reactivity of this layer. It is thought that there is insufficient snow for avalanches below 1500 m.
