Weak layers in the old snowpack can be released by individual winter sport participants, caution is to be exercised in particular on steep shady slopes above the tree line, as well as on steep sunny slopes above approximately 2500 m, especially at transitions from a shallow to a deep snowpack, as well as in areas where the snow cover is rather shallow. Avalanches can in some cases reach large size. <br/> In addition the fresh wind slabs should be taken into account, in particular adjacent to ridgelines and in gullies and bowls above the tree line. The number and size of avalanche prone locations will increase with altitude. <br/> On steep grassy slopes gliding avalanches are to be expected, even large ones in isolated cases, especially on very steep sunny slopes below approximately 2600 m. <br/> The current avalanche situation calls for defensive route selection. 5 to 10 cm of snow will fall. As a consequence of a moderate to strong southeasterly wind, avalanche prone wind slabs will form in particular above the tree line. The no longer entirely fresh wind slabs are covered with new snow in some cases and therefore difficult to recognise. The old snowpack will be weakly bonded in some places. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the unfavourable bonding of the snowpack.
