Valgrisenche

Wind slabs and weakly bonded old snow represent the main danger. Low and intermediate altitudes: The danger of moist and wet avalanches will already increase in the early morning.

Some small and medium-sized dry slab avalanches have been released by people on Saturday. This applies especially on wind-loaded slopes above approximately 2300 m. In some localities 20 to 30 cm of snow, but less in some localities, has fallen since Sunday above approximately 2100 m. The sleet gave rise to moistening of the snowpack in all aspects below approximately 2300 m. The high temperatures from the early morning will give rise to thorough wetting of the snowpack in particular on sunny slopes at intermediate altitudes. Weak layers exist in the snowpack. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind.

As a consequence of rising temperatures the snow drift accumulations will stabilise during the next few days. Moist and wet avalanches are still possible.

Wind slabs and weakly bonded old snow represent the main danger. Low and intermediate altitudes: The danger of moist and wet avalanches will already increase in the early morning.

As a consequence of new snow and a moderate to strong wind from northwesterly directions, avalanche prone wind slabs formed in the last two days in particular in gullies and bowls and behind abrupt changes in the terrain. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack. Even single backcountry tourers or freeriders can release avalanches, including medium-sized ones. Remotely triggered avalanches are possible. In addition from the late morning in the regions exposed to the foehn wind, some moist and wet avalanches are to be expected, especially on steep sunny slopes, as well as on grassy slopes. Backcountry touring and other off-piste activities call for caution.
