In little used terrain a dangerous avalanche situation will prevail.
As a consequence of new snow and a strong to storm force northwesterly wind, further wind slabs will form in gullies and bowls and behind abrupt changes in the terrain. The new snow and wind slabs of the last few days are lying on top of a weakly bonded old snowpack. This applies on west, north and east facing slopes. The avalanche prone locations are numerous, especially in areas close to the tree line, as well as above the tree line. Winter sport participants can release avalanches easily, including large ones. Natural avalanches are still even now possible. In addition wet and gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 1800 m. In places where a lot of rain falls the avalanche danger is greater. This applies in particular in the Kitzbühel Alps.
15 to 30 cm of snow, and even more in some localities, will fall on Tuesday. The wind will be strong to storm force in some cases. The wind will transport the new snow. Further wind slabs will form. The snowpack will be prone to triggering over a wide area. The new snow and wind slabs are lying on top of a weakly bonded old snowpack. Distinct weak layers exist in the bottom section of the old snowpack. This applies in particular on west, north and east facing slopes in areas close to the tree line, and above the tree line. The rain will give rise as the day progresses to gradual and thorough wetting of the snowpack at low altitude.
Hardly any decrease in danger of dry avalanches. Gradual increase in danger of wet avalanches as a consequence of warming.
