Kernpunkte

Avalanche danger is expected to be lower in the cool parts of the day, and rise during warm, sunny periods.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–3
    Wind slabs may be found on lee and cross-loaded terrain at and above treeline. Cornices are fragile and may collapse, especially during warm periods.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    As temperatures warm this weekend, watch for loose wet avalanches on steep sunny slopes.

Confidence

Poor - Due to the number of field observations

Weather Forecast

Expect warm and dry weather for the next three days. The freezing level is forecast to spike up to 2200 m on Saturday afternoon and stay there through Monday. Winds are light to moderate from the north.

Avalanche Summary

No new avalanches have been reported. Avalanche danger is expected to be lower in the cool parts of the day, and rise during warm, sunny periods. As temperatures rise, keep in mind the possibility of glide slabs releasing on smooth rock surfaces - avoid traveling on or under slopes sporting glide cracks.

Snowpack Summary

Cornices are weak and may fail with warm temperatures. Wind slabs may be found in the alpine. On steep, sunny slopes, it is likely that soft, moist snow will develop by day, and crusts may form at night. Below treeline, the snowpack is becoming more uniform as warmth penetrates through. A layer of surface hoar buried in the upper snowpack has been reported in some areas, and is worth investigating before committing to any big alpine terrain. In general, the mid and lower snowpack are strong and well-settled. At the base of the snowpack, weak facets may be found. Smooth rock slabs may act as a sliding surface for the entire snowpack to glide on in specific locations as temperatures rise.
