Keep your MIN reports coming as your eyes on the ground are appreciated.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1.5–2.5

    A triggered windslab has a potential to step down to deeper instabilities with a more destructive potential. Consider testing smaller slopes before committing to a terrain with potential for larger propagation. Watch for hollow sounds and cracking.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    2–3.5

    Natural activity is decreasing as the recent new snow stabilizes, however, triggering this layer would be a high consequence event so cautious decisions and a thorough investigation is necessary.

Snowpack Summary

The midpack is quite supportive and the crust /facet /depth hoar November combo near the ground is the only layer of concern at the moment.
