In sintesi

There is little change right now except some small fresh new wind slabs. The storm forecast for Friday/Saturday looks like it may ride over the ridge and not produce much for us but the models are not in agreement yet.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Wind transport has been forming thin hard slabs on lee features at ridge tops. These may be easily triggered on the right feature.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3
    In many areas the hard wind slab on wind loaded features is bridging the weak facets and depth hoar at the base. There is still a possibility of human triggering a large full depth avalanche on any steep slope.
