Update of the avalanche report for Tuesday 28 January 2025.

Significant increase in avalanche danger in the course of the day. The snow sport conditions outside marked and open pistes are precarious.

earlier in the day it applies above the treeline considerable avalanche danger, so danger level three, below low avalanche danger, so danger level one. later in the day it applies above the treeline high avalanche danger, so danger level four, below moderate avalanche danger, so danger level two.

earlier in the day, above the treeline, we have a wind slab problem. Especially in the aspects West to North to East. Furthermore, earlier in the day, above the treeline, we have a persistent weak layer problem. Especially in the aspects West to North to East. Furthermore, later in the day, above the treeline, we have a new snow problem. This in all aspects. Furthermore, later in the day, above the treeline, we have a persistent weak layer problem. Especially in the aspects West to North to East. Furthermore, later in the day, below the treeline, we have a gliding snow problem. Especially in the aspects East to South to West.

The danger exists in particular in alpine snow sports terrain. As a consequence of new snow and stormy weather more frequent natural avalanches are to be expected as the day progresses, even large ones. Avalanche prone locations for dry avalanches are to be found in particular on steep west, north and east facing slopes above the tree line, also on steep shady slopes in areas close to the tree line. Single winter sport participants can release avalanches very easily, including large ones. The avalanche prone locations are barely recognisable because of the poor visibility, caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain, as well as at the base of rock walls. Extensive experience in the assessment of avalanche danger and great restraint are important. As a consequence of the heavy precipitation gliding avalanches and wet snow slides are to be expected at any time, especially on steep grassy slopes below the tree line.

And now the snowpack:

Over a wide area 30 to 50 cm of snow, and even more in some localities, will fall. As a consequence of a strong to storm force wind from southwesterly directions, deep wind slabs will form. The fresh wind slabs are lying on top of a weakly bonded old snowpack in particular on west to north to east facing aspects. They are lying on soft layers on shady slopes. This applies in particular at high altitudes and in high Alpine regions. New snow is lying on a moist old snowpack. This applies below the tree line. Above the tree line snow depths vary greatly, depending on the infuence of the wind.

The tendency for Wednesday 29 January 2025 indicates a decreasing avalanche danger.

Have a nice day and don't forget to be careful!
