In sintesi

Treat wind loaded and cross loaded terrain with caution.

The persistent weak layer is still around in isolated areas, avoiding large slopes and overhead is advisable.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2

    Small pockets of windslab have developed in immediate lee features.

  • Persistent Slabs

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

    At 60 to 100 cm deep, it can be most likely triggered on steep roll-overs in wind-sheltered terrain around treeline.

Confidence

Moderate

  • Uncertainty is due to the fact that persistent slabs are particularly difficult to forecast.

Avalanche Summary

On Wednesday a small (size 1) human triggered avalanche was reported. It noted that the 20cm of snow failed over a crust.

If you are getting out in the backcountry, consider sharing your observations on the Mountain Information Network (MIN)!

Snowpack Summary

30 cm of recent snow has fallen over a crust that is present up to 1400 m.

In sheltered areas, a layer of weak, feathery surface hoar crystals is buried about 75 cm deep.

At 1100 m and below a prominent crust is just below a skiff of fresh snow and makes for challenging travel.

The snowpack is around 150 cm deep at treeline, tapering quickly with elevation.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
