Wet snow represents the main danger. Wind slabs in high Alpine regions.
The danger of wet avalanches will persist, especially on steep west, north and east facing slopes. In these regions natural avalanches are possible, even large ones. In steep gullies in particular in the regions with a lot of snow wet avalanches can in isolated cases reach areas without any snow cover. Moist and wet avalanches can additionally in some places be released, even by a single winter sport participant. Avalanche prone locations for dry avalanches are to be found on very steep west, north and east facing slopes above approximately 2500 m. The fresh wind slabs can be released by a single winter sport participant, in particular adjacent to ridgelines and in gullies and bowls. Such avalanche prone locations are sometimes covered with new snow and are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable. Avalanches can in very isolated cases penetrate deep layers reach large size.
Up to 2500 m rain will fall. The rain will give rise to a loss of strength within the snowpack especially on steep shady slopes. Up to 15 cm of snow, and even more in some localities, will fall above approximately 2500 m. As a consequence of a sometimes strong southeasterly wind, sometimes easily released wind slabs will form at elevated altitudes. Steep west, north and east facing slopes above approximately 2500 m: Isolated avalanche prone weak layers exist in the top section of the old snowpack. Faceted weak layers exist in the bottom section of the old snowpack.
The danger of moist and wet avalanches will persist. As a consequence of warming during the day and solar radiation more frequent natural avalanches are to be expected, in the regions exposed to a lot of new snow especially.
