Lechtal Alps East

Natural avalanches are to be expected as the day progresses.

An unfavourable avalanche situation will prevail. Wet snow represents the main danger.

In the early morning as a consequence of warming during the day and solar radiation there will be a rapid increase in the danger of wet avalanches. Most and wet avalanches can in some places be released by a single winter sport participant. Caution is to be exercised in particular on very steep slopes below approximately 2500 m. As the penetration by moisture increases the prevalence of the avalanche prone locations will increase as the day progresses. More frequent wet slab avalanches are to be expected in the afternoon. Caution is to be exercised in particular on steep shady slopes between approximately 2200 and 2600 m. Especially here wet avalanches can penetrate even deep layers and reach large size. This also applies in isolated cases in highly frequented off-piste terrain. In steep gullies the avalanches can reach areas without any snow cover. Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m. Such avalanche prone locations are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable.

Outgoing longwave radiation during the night will be severely restricted. For this reason the snowpack will only just freeze. Sunshine and high temperatures will give rise as the day progresses to increasing and thorough wetting of the snowpack below approximately 2800 m. The high humditiy will give rise in the afternoon to a loss of strength within the snowpack also on steep shady slopes. West, north and east facing slopes above approximately 2200 m: Towards its base, the snowpack consists of faceted crystals.

Outgoing longwave radiation during the night will be quite good. The backcountry touring conditions in the morning at elevated altitudes are quite favourable. As the day progresses as a consequence of warming during the day and solar radiation there will be an appreciable increase in the danger of wet avalanches.
