Problemi valanghivi

  • Persistent Slabs

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

    In the alpine hard slabs sit overtop of facets. Dec 14th surface hoar to 6mm can be found in sheltered locations up to 2200m.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1.5–3.5

    Be cautious of thick to thin snowpack areas being likely trigger locations. The persistent slabs have the potential to step down to the weakness at the base of the snowpack.

Tonight, expecting some isolated flurries, with little accumulation. Alpine temperature: Low -11 C, with light SW winds.

Thursday: Cloudy with sunny periods and isolated flurries and trace accumulations. High of -8 C. Light SW winds at ridgetop.

Snowpack Summary

Varied surface conditions with aspect and geographic location. 15-25cm of un-compacted snow over a firm mid-pack with facets and depth hoar lingering near the ground. Mid-December persistent layers, including SH, and SH/FC combos can be found down 25-40cm but, only in isolated and sheltered locations, and almost exclusively in the Icefields region.
