Avalanche Activity

Split avalanche situation: wet snow and persistent weak layer problem!

The avalanche risk is initially moderate from medium altitudes. Depending on the aspect and altitude, it then increases to considerable at different speeds. The persistent weak layer problem must be observed throughout the day. In the shady and north-facing steep terrain at higher altitudes, medium to very rare large snow slabs can be triggered in places by low additional loads. The likelihood of spontaneous wet loose snow and wet to wet slab avalanches increases during the daytime changes, especially on the sunny slopes. Naturally triggered avalanches can reach medium size. If the snowpack tears through to the ground, they could occasionally become large.

Snowpack Structure

The snowpack has already settled significantly. Nevertheless, there is a weak foundation, especially at high altitudes and on shady slopes, due to the kinetic metamorphism and some weak layers in older snow packs. During the night, the snow surface can firm up with the outgoing longwave radiation and is then initially crusted can form differently depending on altitude and aspect. The surface soon loses firmness and softens due to the mild temperatures. At high altitudes and on shady slopes, there may still be dry, soft snow.

Weather Forecast

On Saturday, the sun will once again shine frequently, with a few thin, high patches of cloud moving across the sky at times and not disturbing visibility. The wind will blow weakly to moderately from different directions. It will remain very mild, up to 9 degrees at 1500 metres and around 5 degrees at 2000 metres. The sunny spring weather will take a break on Sunday. Clouds will predominate and there will be a little rain from time to time. Snowflakes will fall from an altitude of around 1500 metres. The sun may appear briefly in places. The wind is weak. At 1500 m 2 degrees, at 2000 m -1 degree.

Tendency

Temporary cooling and clouds. Watch out for persistent weak layer problems. Slight decrease in avalanche danger.
