Avalanche Activity

Areas prone to triggering due to weak layers in the persistent weak layer

The avalanche danger is assessed as low. Slab avalanches can still be triggered in a few places with little additional load, but usually remain small. The danger areas are located in particular in the north-west to east aspects behind ridgelines and terrain edges as well as in the entrance areas to steep gullies and bowls. Prone to triggering is greatest at the transition from a little to a lot of snow and in the edge areas of fresh and older snow packs.

Snowpack Structure

At high altitudes, fresh and older wind slab snow lies in the extended northern and eastern exposures on an unstable snow cover, snowpack with weak layers of faceted crystals and floating snow. Snowdrift accumulations form the snow slab on the existing weak layers and are sometimes prone to disruption. On the sunny slopes, the snow cover, snowpack is mostly settled and quite compact. The snow depths are still below average.

Weather Forecast

Monday night will be clear and cloudless. On Monday, there may still be fog in the valleys, especially in the morning; outside the fog, the air will be very dry and visibility will be correspondingly good. A moderate to brisk, cold southerly wind will blow on the mountains. Temperatures at 2000 metres are around -4 degrees.

Tendency

No change in avalanche danger. Partly strong southerly winds in dry air. No snow in sight at the moment!
