In sintesi

Generally safe avalanche conditions.  Watch for unstable snow on isolated solar features.

Problemi valanghivi

  • Cornices

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

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

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–3

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

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2.5

    Varied sensitivity on solar aspects, likelihood increases on the steepest slopes. It may be possible to trigger deeper instabilities once initiated.

Weather Forecast

Tonight: Flurries. Light SW winds.

Friday: Cloudy with sun, isolated flurries. Alpine temperature: High -5 °C. Ridge wind SW: 20 km/h gusting to 50 km/h. Freezing level: 1600 m.

Saturday: Flurries. Accumulation: 6 cm. Alpine temperature: Low -13 °C, High -7 °C. Ridge wind southwest: 20 km/h gusting to 55 km/h. Freezing level at valley bottom.

Snowpack Summary

Warm temps and high solar input has created typical spring like conditions with moist snow on solar aspects from daytime heating, TL and below. Continuing SW winds have redistributed the snow pack, forming hard slabs in the ALP. The mid pack is supportive in deep areas, but shallow snowpack areas are weak and will break down fast with temp swings.

Avalanche Summary

No new avalanche activity observed or reported

Confidence

Intensity of incoming weather systems is uncertain
