In sintesi

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Soft slab conditions on lee alpine aspects appear to have bonded well in most locations. Approach these features with caution and test bonding on the slope from a safe area before committing.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3
    Large cornices or surface avalanches are the likely trigger for this layer.

Weather Forecast

Warm daytime temperatures with good overnight freezing, light alpine winds, and no snow forecasted will make for enjoyable conditions in the mountains.

Snowpack Summary

A strong rain crust forms the surface at treeline and below.  Up to 35cm of storm snow overlies a variable snowpack above treeline.  Soft wind slabs have formed on lee aspects as a result of strong SW winds.  The deep persistent weakness (basal facets and depth hoar) make up the base of the snowpack.

Avalanche Summary

No new avalanches observed.

Confidence

The weather pattern is stable
