Kernpunkte

Although natural avalanches are unlikely right now, human triggered avalanches are still possible. Be cautious around shallow areas in big terrain, where the consequence of triggering an avalanche would be serious.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible

    Be aware of solar warming which could trigger a slide on this layer which in turn may step down and release the basal weakness.

  • Deep Persistent Slabs

    Natural activity has tapered off on this layer, but it is still possible to trigger big avalanches in shallow locations.

Weather Forecast

The drought continues with warm day time temperatures and light westerly winds. Colder air pushes in on Sunday which will reduce the impact of the sun on the snow.

Snowpack Summary

Shallow and weak snowpack sits on 10-20cm of basal facets. Midpack hard slabs provide bridging above treeline and into the alpine. Extensive scouring at upper elevations. Surface hoar growth observed in the last few days up to size 5mm below treeline and up to size 3mm above treeline.

Avalanche Summary

Field patrols observed three size 1.5 to size 2 slabs on solar aspects in the alpine that had released in the last 24 to 48 hours.
