Rare avalanche prone locations in persistent weak layers of snow

Rare avalanche prone locations in persistent weak layers of snow

The avalanche danger is low. Small avalanches in particular can occasionally be triggered by one person in shady slope high alpine regions above 2600 metres. This occurs where the older foehn drift snow has formed a suitable shelf above a weak layer (usually in persistent weak layer). In addition to the risk of burial, the risk of falling and injury should be taken into account.

A little new fallen snow lies on a hard-frozen surface. In high, shady slopes, the melt-freeze crust is partly covered by edged snow with no binding, which can serve as a weak layer in exceptional cases, but usually does not tend to propagate fractures. Fractures are most possible within the snow cover, above the hardness of the old snow foundation from early winter or in weak layers near crusts. The snow depth is well below average at all altitudes.

Thursday will be increasingly sunny. Residual clouds will clear in the morning. In the open high areas, winds will be brisk from southerly to easterly directions at times, reaching speeds of around 50 kilometres per hour. At medium altitudes, the wind will mostly be moderately strong. At 2000 metres the temperature will be around -3 degrees Celsius, at 3000 metres around -7 degrees Celsius.

The avalanche danger remains low.
