- Level 3, Considerable Danger: The snowpack is only moderately to weakly bonded in many places. Triggering is possible even with low additional loads, especially on steep slopes in the indicated aspects and altitude zones (see Chapter 8.3.2). Isolated slab avalanches can be released even from well outside the starting zone (remote triggering).
The danger of natural avalanches can vary greatly; in case of weak snowpack layering and shallow snow cover, medium-sized avalanches are to be anticipated only sporadically. If this danger level is announced after new snow or in connection with (daytime) warming, however, isolated large avalanches are likely as well, depending on the influence of the weather. Such conditions give rise to the use of explosives (especially in the case of new snow) or temporary closures (especially if temperatures are expected to rise) for exposed parts of transportation routes and, above all, the ski slopes that are subject to protection by technical measures. Backcountry touring and freeriding activities are inadvisable without experience and the ability to assess avalanche danger. Steep slopes in the indicated aspect and altitude zone are to be avoided as far as possible.
About 45 per cent of all fatalities occur at this danger level.
