Kernpunkte

A lot more rain, sometimes turning to heavy snow, is forecast for Friday. This will put considerable pressure on the snowpack, and it would be wise to avoid avalanche terrain until Saturday.

Lawinenprobleme

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely
    Größe
    1–2

    The rain is likely to destabilize the light snow that was on the surface before the storm.

  • Wet Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–2

    In places where a wind slab problem existed before the storm, rain could percolate to an underlying weak layer and trigger a wet slab. The probability is low, but the danger exists.

Avalanche Summary

Few observations in the field today. Le Couloir reported an avalanche of wet loose snow : https://www.facebook.com/share/r/15tZh46rBH/

If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

Moist snow on the surface, which could form a crust before the snowfall forecast for Friday afternoon. Snow cover in the alpine has probably diminished considerably due to extreme southerly winds, rain and high temperatures.

The middle of the snowpack is well consolidated, resting on a layer of rounding facets. The height of the snowpack currently varies from 100 cm to 200 cm.

  • Avoid avalanche terrain during periods of heavy rain.
  • Keep in mind that the high density of wet avalanches can make them destructive.
