In sintesi

Warm and sunny weather may produce loose snow avalanches, especially on southerly aspects. The danger is rated for the warmest part of the day.

Problemi valanghivi

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Sunshine and air temperatures above 0 C can rapidly increase the likelihood of triggering loose wet avalanches.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3
    Human triggering of large deep persistent slab avalanches remains possible; especially in rocky, alpine terrain with a shallow or highly variable snowpack depth.

Avalanche Summary

There have been no reports of avalanches in the past few days.

Snowpack Summary

Around 5 cm of recent new snow sits on a crust.The recent prolonged warm spell has transitioned the snowpack on sun exposed slopes in the alpine and all aspects at treeline and below toward becoming moist or wet, during the heat of the day. In these areas that have entered spring conditions, the avalanche hazard will fluctuate greatly depending on the strength of the overnight freeze and how quickly the snowpack is warmed up each day. Check out this guide to managing avalanche hazard during spring conditions HERE.In areas that remained more sheltered from the heat, like northerly aspects in the alpine, there is still a dry snowpack with a well settled slab sitting on weak facets (sugary snow).Lower down in the snowpack, the base is composed of weak facets.
