In sintesi

The snowpack is not improving. This is not the time to venture into big terrain. Large natural avalanches continue to occur.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2.5
    Expect to find wind slabs at all elevations. The depth and sensitivity to triggering are highly variable across the forecast region.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità

Weather Forecast

Generally calm and sunny on Wednesday with Alpine temperatures near -6 Celsius. Light flurries are expected to move into the region late Wednesday or Thursday morning, but snow accumulations will not be significant.

Avalanche Summary

A few naturally triggered slabs in Alpine terrain on North, East and West aspects in the past 24 hours up to size 2.5. In addition, a couple of small solar triggered avalanches occurred on steep south-east and south aspects in the past 24 hours.

Snowpack Summary

Surface hoar was observed up to 2200m in sheltered locations. This may be a layer of concern in the future if it ever snows again. Moist snow was found on solar aspects in the Alpine and at Treeline by early afternoon today. Wind slabs are widespread at all elevations except for very sheltered areas below treeline. Compression Test results today at TL on an East aspect produced moderate shears down 100cm in the basal facets. The bottom half of the snowpack remains very weak and facetted.
