Avalanche Activity

Gliding avalanches and moist snow slides are the main danger.

On steep grassy slopes small and medium-sized gliding avalanches are possible. Caution is to be exercised in areas with glide cracks. As a consequence of warming during the day and the solar radiation, the likelihood of moist and wet avalanches being released will increase gradually, especially on sunny slopes, as well as on steep shady slopes also at intermediate and high altitudes.

Snowpack Structure

Outgoing longwave radiation during the night will be reduced. The surface of the snowpack will only just freeze and will already soften in the late morning. This applies in particular on sunny slopes at intermediate and high altitudes, as well as on shady slopes below approximately 2400 m. The more recent wind slabs are lying on soft layers on very steep shady slopes at elevated altitudes.

Tendency

The weather will be exceptionally warm. Further increase in danger of wet and gliding avalanches as a consequence of warming.
