Hochschwab Mountains

Avalanche danger already increases in the morning!

Avalanche danger already increases in the morning!

The avalanche risk is low in the morning hours and then increases to moderate. There is a danger of wet loose snow and slab avalanches from terrain that has not yet been unloaded as incoming radiation and warming increase. These can detach themselves or be triggered by a small additional load from people and are usually small to medium in size. Gliding avalanches are possible in isolated cases.

During the night, the isothermal snow cover can consolidate a little due to outgoing longwave radiation. However, it quickly softens again with solar radiation and warming. The soaking can reactivate old weak layers in the persistent weak layer, especially on the north side. In all aspects, the soaked snowpack can lose its stability or begin to glide on slippery ground. At low altitude and on the sunny slopes, the snow cover is developing rapidly.

In the night to Friday, the sky will largely clear up in the south of the Alps, but low residual clouds will persist in the north. Friday morning will be mostly sunny in the southern mountain ranges. Towards the north, a few low clouds will persist, which may also shroud the peaks in fog. In the afternoon, spring clouds will develop everywhere, but the tendency to shower will be relatively low. The temperature at an altitude of 2000 metres will be between +2 and +5 degrees. Moderate winds from the northwest.

On Saturday, it will be very sunny and largely dry once again under the influence of high pressure, with isolated unproductive showers remaining the exception. There will be little change to the avalanche situation.
