Border Graie Alps

The danger of moist snow slides and avalanches will increase a little during the day.

The danger of moist snow slides and avalanches will increase a little during the day.

A clear night will be followed in the early morning by favourable conditions. As a consequence of warming during the day and the solar radiation, the likelihood of moist and wet avalanches being released will increase a little in particular on rocky sunny slopes at low and intermediate altitudes. Individual small to medium-sized moist and wet avalanches are possible below approximately 2800 m. Faceted weak layers exist in the bottom section of the snowpack at high altitudes and in high Alpine regions. Dry avalanches can in very isolated cases be released in the old snowpack and reach medium size.

Low altitudes as well as steep sunny slopes: As a consequence of rising temperatures and solar radiation a crust formed on the surface during the last few days. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack on sunny slopes. Intermediate and high altitudes as well as shady slopes: Towards its base, the snowpack is faceted. The snowpack is largely stable and its surface consists of loosely bonded snow lying on a strong crust.
