Weakly bonded old snow and wet snow require caution.
In some places avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on very steep west, north and east facing slopes above approximately 2400 m and in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are small. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. As a consequence of warming during the day and solar radiation small wet loose snow avalanches are to be expected below approximately 2600 m, in particular on extremely steep sunny slopes. In addition further small to medium-sized gliding avalanches are possible. Caution is to be exercised in particular on steep grassy slopes.
Below approximately 2600 m: Steep sunny slopes: The high temperatures will give rise to increasing moistening of the snowpack. Avalanche prone weak layers exist deeper in the old snowpack in particular on steep shady slopes. The snowpack will be subject to considerable local variations. From a snow sport perspective, in most cases insufficient snow is lying.
Decrease in avalanche danger. The weather will be mild.
