Middle Lys Valley

A clear night will be followed in the early morning by favourable conditions, but the danger of wet avalanches will increase later. Backcountry tours should be started early and concluded timely.

A clear night will be followed in the early morning by favourable conditions, but the danger of wet avalanches will increase later. Backcountry tours should be started early and concluded timely.

Outgoing longwave radiation during the night will be quite good. Increase in danger as a consequence of warming during the day and solar radiation, especially at the base of rock walls and behind abrupt changes in the terrain on very steep sunny slopes. The danger of moist and wet avalanches will increase during the day, in the regions exposed to heavier precipitation in particular below approximately 2900 m. Small and medium-sized natural avalanches are possible, in the event of solar radiation in particular at high altitudes and in high Alpine regions and, in the regions exposed to heavier precipitation especially. The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.

10 to 25 cm of snow, and even more in some localities, has fallen since Tuesday above approximately 2600 m. The wind was moderate in the vicinity of peaks in particular in the southeast and in the northeast. Over a wide area 5 to 10 cm of snow, and even more in some localities, fell on Friday above approximately 2300 m. The high humditiy gave rise to moistening of the snowpack also at high altitude. Below approximately 2600 m the snowpack is wet all the way through. In particular sunny slopes and south and east facing slopes: In many cases new snow is lying on a hard crust. Below approximately 2200 m a little snow is lying.

The avalanche danger will persist.
