Lechtal Alps East

Gliding snow represents the main danger. Fresh wind slabs require caution.

Gliding snow represents the main danger. Fresh wind slabs require caution.

On steep grassy slopes medium-sized and, in isolated cases, large gliding avalanches are possible. This applies especially on steep slopes below approximately 2600 m. Areas with glide cracks are to be avoided. Since Tuesday sometimes avalanche prone wind slabs will form adjacent to ridgelines and in gullies and bowls. Such avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m. The number and size of avalanche prone locations will increase with altitude.

As a consequence of a strong wind from westerly directions, avalanche prone wind slabs will form since Tuesday. This applies in particular on very steep northwest, north and east facing slopes above approximately 2400 m. Outgoing longwave radiation during the night will be quite good over a wide area. The surface of the snowpack will freeze to form a strong crust and will soften during the day. This applies in particular on sunny slopes at intermediate and high altitudes, as well as on shady slopes below approximately 2200 m.

The danger of moist avalanches will increase. As a consequence of rising temperatures the snow drift accumulations stabilised.
