Ampezzo Dolomites

Wind slabs and wet snow represent the main danger.

Wind slabs and wet snow represent the main danger.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the high Alpine regions, so that the avalanche danger should be investigated especially thoroughly in the relevant locality. A clear night will be followed by favourable conditions generally. The surface of the snowpack will freeze to form a strong crust will soften during the day. In all regions medium-sized and, in isolated cases, large moist and wet avalanches are possible as a consequence of warming, in particular on very steep slopes, and at the base of rock walls. The wind slabs can be released on very steep shady slopes and at high altitude. This applies in particular in the regions exposed to precipitation,. Backcountry tours should be started very early and concluded timely.

In some localities 30 to 40 cm of snow, and even more in some localities, has fallen since Wednesday above approximately 2500 m. Up to 2400 m rain has fallen over a wide area. Outgoing longwave radiation during the night will be quite good over a wide area. Towards its surface, the snowpack is hard and its surface has a melt-freeze crust that is strong in many cases. The solar radiation will give rise as the day progresses to increasing moistening of the snowpack. The conditions in all altitude zones are spring-like.

The conditions will facilitate a gradual strengthening of the snowpack in all aspects.
