Kernpunkte

Does green mean go? No! Keep your wits about you: avalanches are still possible in isolated areas.

Lawinenprobleme

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    3–5
    Cornices are fragile and may collapse, especially during warm periods. Isolated areas of wind slab may also be found.

Confidence

Fair - Timing or intensity of solar radiation is uncertain on Saturday

Weather Forecast

Any lingering precipitation should peter out by Saturday, leading into a dry week. Temperatures warm on Sunday, when the freezing level is forecast to spike up to 2700 m. Winds are light to moderate from the north.

Avalanche Summary

Recent activity has been limited to small loose wet avalanches on steep sunny terrain features.

Snowpack Summary

Cornices may be large and potentially fragile. On high north-facing terrain light amounts of cold, low density snow overlie a widespread thick hard crust. Below about 2000 m, there is no snow on the crust and surface runnels show the effect of last week's rain showers. Sun-exposed slopes became moist, or wet with recent daytime warming and solar radiation and are also likely refrozen. Below the surface crust, the snow may still be moist; however, the mid and lower snowpack are generally strong and well-consolidated. Most of the terrain below treeline is below threshold for avalanche activity.
