In sintesi

Warm and sunny weather may produce loose snow avalanches, especially on southerly aspects if solar radiation is strong. 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

    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

On Friday, there were reports of a few loose wet avalanches up to size 1.5 out of steep, sun-exposed terrain.

Snowpack Summary

The snowpack on sun exposed slopes in the alpine and all aspects at treeline and below is 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.
