Ascent to moderate avalanche danger!

The avalanche risk is low in the morning, but then increases to moderate at higher altitudes with a sufficiently thick snowpack. Spontaneous or occasional small to medium wet snow avalanches triggered by people are possible from undischarged steep terrain in all aspects. Only high alpine and on shady slopes could slab avalanches be triggered in very steep terrain, in some cases by low additional loads.

Snowpack

The snowpack can consolidate on the surface as a result of outgoing longwave radiation at night, and then breaks down at different rates during the day depending on the aspect and altitude, becomes soft and loses firmness again. Inside, it is wet up to high altitudes anyway, otherwise it is damp and therefore unstable and continues to degrade. Milder temperatures and frequent sunshine further destabilise the snowpack. Only on shady slopes can there still be isolated weak layers in the old snowpack. Low and progressively also sunny mid-altitude locations are bare.

Tendency

Moderate avalanche danger due to rain and snow showers.

Low avalanche danger!

The avalanche risk is again subject to slight daytime changes but remains low. Only on steep slopes at higher altitudes with a sufficiently thick snowpack are local, mostly small, sometimes medium wet snow avalanches still possible in all aspects during the day.

Inside, it is wet up to high altitudes anyway, otherwise it is damp and therefore unstable and continues to degrade. Milder temperatures and frequent sunshine further destabilise the snowpack. Low and progressively not only sunny mid-altitude locations are covered in snow.
