Nock Mountains

Note the persistent weak layer

Note the persistent weak layer

The avalanche risk is moderate from the sparse high forest upwards. In a few places, avalanches can still be triggered by a small additional load in the persistent weak layer and reach medium size. Be careful at the transition from a little to a lot of snow.

Even mostly easily recognisable snowdrift accumulations can be disturbed by individuals in some places. Superficial avalanches remain small, but can reach medium size if they break through to the upper part of the persistent weak layer. Caution is also advised on and below cornices.

The snow surface is variable and characterised by storms. Drift snow packs are usually easily recognisable, but the unfavourable old snowpack underneath is not. Breaks are possible between the drift snow layers and at the transition to the persistent weak layer. The old snowpack is particularly weakened on western, northern and eastern slopes above around 2000 metres due to layers of faceted crystals and deep frost as well as a foundation of floating snow close to the ground.

There will be no precipitation overnight in the Nockberge region. On Friday, the clouds will soften and often let the sun shine. During the day, spring clouds will form again, restricting visibility in places. The clouds will clear again in the late afternoon. A moderately strong to brisk north-westerly wind will blow. At 1500 metres the temperature will be -2 to 1 degree, at 2000 metres -6 to -3 degrees.

On Saturday, changeable weather and similar avalanche risk.
