Points saillants

In the late morning as a consequence of warming during the day and solar radiation there will be an increase in the danger of moist avalanches. Afternoon: Up to 2300 m rain will fall in some localities.

Avalanche Activity

In the late morning as a consequence of warming during the day and solar radiation there will be an increase in the danger of moist avalanches. Afternoon: Up to 2300 m rain will fall in some localities.

The surface of the snowpack will freeze to form a strong crust and will already soften in the late morning. In the late morning the likelihood of moist small and medium sized avalanches being released will increase gradually in all aspects. Above approximately 2700 m: Avalanches can in isolated cases be triggered in the old snowpack and reach large size. Up to intermediate altitudes rain will fall in the afternoon in some regions. Backcountry tours and ascents to alpine cabins should be started and concluded early.

Snowpack Structure

The surface of the snowpack will freeze to form a strong crust. Sunshine and high temperatures will give rise in the late morning to increasing moistening of the snowpack. Afternoon: Over a wide area light rain to 2300 m. These weather conditions will give rise to moistening of the snowpack over a wide area. Isolated avalanche prone weak layers exist in the snowpack at high altitudes and in high Alpine regions. Below approximately 2000 m a little snow is lying.

Tendency

Gradual increase in danger of dry and wet avalanches as a consequence of the precipitation.
