In sintesi

Predominantly favorable conditions

Problemi valanghivi

  • Wet snow

    • Above 1,500 m

Weather Forecast

A night of mild temperatures and foehn wind. On Saturday, very windy. Sunshine will often penetrate the clouds full of dust from the Sahara desert, thereby creating diffuse light conditions. Temperatures will drop. At 2000m: +4 degrees. Winds will be moderate, stronger in the foehn lanes, from the southwest.

Tendency

As temperatures drop, slighlty decreasing avalanche danger

Avalanche Activity

Due to daytime warmth, slides and wet-snow avalanches

Especially on sun-bathed steep slopes, increasingly frequent slides and small-to-medium avalanches are possible due to solar radiation and daytime warming. In addition, on steep grass-covered slopes where the snow is sufficient or over smooth ground, the danger of small glide-snow avalanches exists. Further, isolated danger zones occur esp. on steep shady ridgeline slopes. Small slab avalanches can be triggered by winter sports enthusiasts in isolated cases. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution.

Snowpack Structure

On steep shady slopes at high altitudes, the latest fresh fallen snow often lies deposited atop soft layers, bonding usually good. Mild nocturnal temperatures, reduced outgoing longwave radiation, only a breakable crust can form. On steep high-altitude north-facing slopes the snow is often still powdery. The generally shallow old snowpack is mostly well consolidated. On sunny slopes the uppermost layers moisten during the daytime, lower altitude slopes are becoming bare of snow. Below 1500m there is little snow on the ground.
