Border Pennine Alps

Individual weak layers exist in the snowpack. Increase in danger of dry avalanches as a consequence of the strong wind.

A clear night will be followed in the early morning by favourable conditions. As a consequence of a gathering strong northeasterly wind, clearly visible wind slabs will form in the afternoon adjacent to ridgelines and in gullies and bowls as well as in high Alpine regions. These can be released by a single winter sport participant and reach medium size. Additionally in some places avalanches can be released in the old snowpack and reach medium size. Mostly these are very deep but can still be released by large loads.

As a consequence of mild temperatures and solar radiation the wind, the snowpack consolidated during the last few days. The spring-like weather conditions gave rise to moistening of the snowpack in particular on sunny slopes below approximately 2600 m, also on shady slopes below approximately 2100 m. Towards its surface, the snowpack is dry; its surface consists of loosely bonded snow. After a clear night this applies in particular above approximately 2200 m.

As a consequence of the strong wind the size of the avalanche prone locations will increase. Until Monday the weather will be very warm. Moist and wet avalanches are still likely to occur in particular during the day.
