In sintesi

Great skiing with lots of fresh snow recently, but stick to conservative lines. A very serious accident on Sunday indicates that human-triggering is a very real possibility. Also, keep a close eye on the solar radiation at this time of year.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    2–4
    Previously formed wind slabs are now hidden by up to 25cm of recent snow. These slabs are most commonly found in Alpine terrain and open areas at Treeline.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    2–5
    The Feb 10th persistent weak layer remains a concern and continues to give variable results in snowpack tests. A very serious avalanche accident occurred on this layer on Sunday (see photos).

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2
    Intense periods of solar radiation and/or warm temperatures will cause sluffing on solar aspects.

Confidence

Fair - Timing or intensity of solar radiation is uncertain

Weather Forecast

Tuesday should bring a mix of sun and cloud with Alpine temperatures near -3 degrees. Winds will be light from the West.

Avalanche Summary

Isolated snow-balling was observed in steep solar aspects today. The skier-triggered slide from yesterday was visited today for evaluation. This slide was a size 2.5 (originally sized as a 2.0) and occurred on a North aspect at 2200m. The failure plane for the avalanche was the Feb 10th layer down an average of 110cm in this area. Photos have been posted on our Facebook page.

Snowpack Summary

8 to 12cm of new snow overnight with no wind effect. The storm snow over the past week has settled to 50cm. Moist snow was observed on solar aspects this afternoon as well as below 2000m on all other aspects. The Feb 10th layer is buried 90 to 120cm and remains a serious concern in the snowpack.
