Avalanche prone weak layers exist deep in the snowpack in particular on steep, little used north and east facing slopes. These can be released easily. Sometimes the avalanches are medium-sized. The avalanche prone locations are to be found especially adjacent to ridgelines and in gullies and bowls and at transitions from a shallow to a deep snowpack. These avalanche prone locations are covered with new snow and are difficult to recognise. Artificially triggered avalanches and field observations confirm this situation.
As a consequence of warming during the day and solar radiation more frequent small and, in isolated cases, medium-sized gliding avalanches and moist snow slides are to be expected. Backcountry touring and other off-piste activities call for careful route selection.
