Northern Lepontine Alps

More moist avalanches are possible as the day progresses. In addition the clearly visible wind slabs should be taken into account.

More moist avalanches are possible as the day progresses. In addition the clearly visible wind slabs should be taken into account.

Outgoing longwave radiation during the night will be good. Sunshine and high temperatures will give rise as the day progresses to slight moistening of the snowpack on sunny slopes, caution is to be exercised in particular on very steep slopes below approximately 2600 m, and at the base of rock walls. In steep gullies moist avalanches can reach medium size. The wind slabs of the last few days are lying on weak layers in high Alpine regions. They can still be released in some cases in particular on north to east to southeast facing aspects above approximately 2500 m. There is a danger of falling on the hard snow surface. This applies in particular in the early morning.

The conditions are wintry at high altitude. Individual weak layers exist in the snowpack on wind-loaded slopes. Adjacent to ridgelines hardly any snow is lying. Low and intermediate altitudes and very steep sunny slopes: The conditions are spring-like. Less snow than usual is lying. The high temperatures gave rise to moistening of the snowpack below approximately 2500 m.

The weather will be mild. The meteorological conditions will foster a gradual strengthening of the near-surface layers.
