Upper Susa and Chisone Valleys

Significant increase in danger of moist and wet avalanches as a consequence of warming during the day.

Significant increase in danger of moist and wet avalanches as a consequence of warming during the day.

As a consequence of warming during the day and solar radiation moist and wet avalanches are to be expected as the day progresses. This applies in particular on very steep slopes below approximately 3000 m, as well as at the base of rock walls. In particular on very steep sunny slopes moist avalanches can penetrate even deep layers and reach very large size in isolated cases. In very isolated cases, the wet avalanches can reach low altitudes from starting zones where no previous releases have taken place. Backcountry tours and off-piste skiing should be started and concluded very early.

Above approximately 2000 m there is still a very large amount of snow. The surface of the snowpack will only just freeze and will soften earlier than the day before. Sunshine and high temperatures will give rise as the day progresses to rapid moistening of the snowpack over a wide area below approximately 3000 m.

The weather will be very warm. The surface of the snowpack will freeze very little and will already soften in the late morning.
