Lechtal Alps East

Even single freeriders can release avalanches easily. As a consequence of warming, the natural activity of wet avalanches will appreciably increase.

As a consequence of new snow and warming a dangerous avalanche situation will persist.

Large quantities of fresh snow and the wind-drifted snow are lying on top of a weakly bonded old snowpack. As a consequence of warming during the day and solar radiation wet avalanches are to be expected as the day progresses. Areas close to the tree line as well as above the tree line: Winter sport participants can release avalanches easily. Avalanches can in some cases penetrate deep layers and reach large size, in particular on west, north and east facing slopes. The avalanche prone locations are numerous. Individual avalanche prone locations are to be found also on southeast, south and southwest facing slopes above approximately 2600 m. Caution is to be exercised in particular in little used terrain, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Remotely triggered avalanches are possible. As a consequence of warming during the day and solar radiation loose snow avalanches are to be expected as the day progresses. This applies in particular on steep sunny slopes. In particular on steep, rather lightly snow-covered east and west facing slopes the wet avalanches can penetrate even deep layers and reach large size in isolated cases. In addition gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 2000 m.

Tuesday: More snow than expected has fallen. This applies in particular in the Allgäu Alps and in the Central Lechtal Alps. 20 to 30 cm of snow, and even more in some localities, has fallen above approximately 2000 m. Up to 2000 m rain has fallen. The wind was strong to storm force in some cases. On Wednesday it will be exceptionally warm. The snowpack remains prone to triggering. Large quantities of fresh snow and the wind-drifted snow of the last few days are bonding only slowly with the old snowpack. The various wind slabs have bonded insufficiently with each other and the old snowpack. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The rain gave rise to increasing and thorough wetting of the snowpack at low and intermediate altitudes.

As a consequence of warming and solar radiation, the activity of wet avalanches will increase.
