In sintesi

Avalanche conditions are generally safe. Be mindful of your exposure to cornices when travelling on and below ridgelines. 

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1.5–3

    Cornices may be weak and reactive to human triggers. They are a significant hazard alone, and may produce large slab avalanches as they fall onto the slope below. Cornice falls are more likely as temperatures warm each day, or when strong sunshine is present. 

Confidence

High - The snowpack structure is generally well understood.

Avalanche Summary

No new avalanches have been reported over the past week. 

Reports are limited at this time of year. Please let us know what you're seeing by filling out a MIN report!

Snowpack Summary

A light amount of new snow has added to heavily wind-affected surfaces from last week's strong northerly winds.

On south and west facing slopes up to 1400 m a surface crust from spring sunshine can be found, while other aspects hold dry snow. The mid-snowpack is generally strong, overlying weak basal facets at the base of the snowpack. 

Terrain and Travel

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
