Snowpack

In Lower Valais, northern Valais and the Bernese Oberland, there is as much snow at high altitudes as usual for this time of year, but less in the other regions. There is particularly little snow on the southern flank of the Alps and at intermediate altitudes on the eastern part of the northern flank of the Alps. At 2000 m, there is 30 to 50 cm of snow on the northern flank of the Alps, 10 to 30 cm in southern Lower Valais, northern Upper Valais, the Gotthard region and northern and central Grisons, and less than 10 cm elsewhere.

Weak layers in the snowpack are located in particular on northern and eastern slopes above approximately 2400 m. Particularly in southern Valais and in some parts of the inneralpine regions of Grisons, human activity can cause these layers to fracture and easily trigger avalanches.

Below approximately 2400 m, the snowpack is moist under the mostly brittle melt-freeze crust; below 2100 m, it is saturated. Isolated wet and gliding avalanches are possible with the sunshine and rising temperatures during the daytime.

Weather forecast to Friday

The skies will clear during the night. During the day it will be mostly sunny in the mountains with occasional high cloud cover.

Fresh snow

Temperature

At midday at 2000 m, around +5 °C

Wind

Mostly light, occasionally moderate from the southwest at high altitudes

Weather review for Thursday

It was cloudy during the night into Thursday and during the day, very cloudy in the east in particular.

Fresh snow

-

Temperature

At midday at 2000 m, between around +4 °C in the north and 0 °C in the south

Wind

Mostly light, moderate at times, initially from the southwest, later from the north

Outlook

On Saturday and Sunday it will be mostly sunny and mild with light winds in the mountains.

The danger risk of dry avalanches will slowly decrease. In regions with persistent weak layers in particular, human activity can still trigger avalanches in places, possibly large avalanches.

The danger of wet and gliding avalanches will increase slightly during the day with the sunshine and rising temperatures.
