Avalanche Activity

Note the persistent weak layer problem in the extended northern sector!

The avalanche risk is low. Nevertheless, there is still a persistent weak layer problem in the extended northern sector. Occasionally, mainly in very steep gullies and bowls, slab avalanches can be triggered by people. The avalanche prone locations are usually difficult to recognise and are often located in transition areas from a little to a lot of snow. On the sunny slopes, the softened, barely stabilised snowpack can trigger small wet snow avalanches.

Snowpack Structure

Depending on the degree of cloud cover overnight and the wind influence of the last few hours, at least a thin melt-freeze crust will form, which will soften during the daytime changes on the sunny side. The snowpack will become increasingly damp or wet here. On the shady slopes, there are still areas with a soft (faceted) snow surface at higher altitudes, but the layer is often already hard here too. Below this, there are still weak layers of large faceted crystals in the lower part of the snowpack, especially close to the ground. Medium (sunny slopes) and low altitudes are largely free of snow.

Weather Forecast

The night to Tuesday will be increasingly clear, especially in the second half. The initially brisk wind from the south-east to south-west will weaken considerably. The sun will shine more frequently again on Tuesday. However, it will not be completely cloud-free, but the summits will be mainly clear. Spring clouds in the afternoon will hardly bring any showers. The temperature will be between -1 and +3 degrees at an altitude of 2000 metres and around +4 degrees at an altitude of 1500 metres. A weak to moderate south-westerly wind will blow.

Tendency

Weak disturbances on Wednesday, with some precipitation in places, it will remain mild. No significant change in the avalanche risk is expected.
