In sintesi

With cooling trend and small amounts of precipitation in the forecast we are facing generally safe avalanche conditions.Be mindful of the potential for low probability high consequence scenario.

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1.5–3

    Cornices can be extremely destructive alone or, may initiate deeper layers in the snowpack below.

  • Persistent Slabs

    • Alta quota

    • Sotto il limite del bosco

    More activity noted at this layer, mostly initiated by large loads (cornices) in steep terrain.

Weather Forecast

Sunday: Mainly cloudy with scattered flurries. Accumulation: 4 cm. Alpine temperature: High -6 °C. Mostly light ridge wind occasionally gusting to 30 km/h. Freezing level: 1600 metres.Monday: Flurries. Accumulation: 8 cm. Alpine temperature: Low -9 °C, High -8 °C. Ridge wind light to 20 km/h. Freezing level at valley bottom.

Snowpack Summary

Up to 10cm of new snow creating thin slabs in ALP lees. Warm temps and high solar input have created sun crust on solar aspects TL and below. Snowpack becoming isothermal 1700m and below on all aspects. Generally strong mid-pack with exception in shallow areas.

Avalanche Summary

No new avalanche activity observed or reported today, however, there have been reports of sporadic large avalanches in isolated ALP features in the last couple weeks. These slides are believed to be triggered by large cornice failures and ran in heavily wind loaded features with wide propagation. Beware of low probability, high consequence scenario

Confidence

The weather pattern is stable
