Avalanche Activity

Gliding avalanches and moist snow slides are the main danger.

On steep grassy slopes medium-sized gliding avalanches are possible. As a consequence of warming during the day and the solar radiation, the likelihood of gliding avalanches and wet snow slides being released will increase quickly in all aspects, not only on sunny slopes, including on steep shady slopes at intermediate and high altitudes. In isolated cases, wet avalanches can reach intermediate altitudes in steep gullies. Areas with glide cracks are to be avoided.

Snowpack Structure

Outgoing longwave radiation during the night will be reduced in some case. The surface of the snowpack will freeze very little and will already be soft in the early morning. This applies on sunny slopes in all altitude zones, as well as on shady slopes also at intermediate and high altitudes.

Tendency

The danger of wet and gliding avalanches will decrease gradually, but only during the night.
