Avalanches can in some places be released by a single winter sport participant and reach medium size.
Single winter sport participants can release avalanches in some places. 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. Mostly the avalanches are medium-sized. The avalanche situation is more favourable in highly frequented off-piste terrain. In addition medium-sized gliding avalanches are possible. Meticulous route selection is recommended.
The deep wind slabs of the last few days are lying on top of a weakly bonded old snowpack in particular on west to north to east facing aspects above the tree line. They are covered with new snow and therefore barely recognisable. The old snowpack will be moist at low and intermediate altitudes. Above the tree line snow depths vary greatly, depending on the infuence of the wind.
Gradual decrease in avalanche danger as a consequence of warming.
