Avalanche Activity

Snowdrift accumulations can still be prone to disruption in some cases

The avalanche danger is moderate above 2400 metres and low below that. In the higher altitudes, small to maximum medium-sized snow slabs can still be triggered in a few places by low additional loads in the wind slab. The frequency and extent of the danger zones increase slightly with altitude. The danger zones are located adjacent to the ridgeline and also behind terrain edges far from the ridge as well as in steep gullies and bowls. In shady slopes at high and high alpine altitudes, small to medium-sized avalanches in persistent weak layers are still possible in isolated cases.

Snowpack Structure

The snow cover, snowpack is highly variable and below average. Fresh and older, brittle wind slabs lie on a crusted can form surface. Underneath are layers of faceted crystals, deep rime and melt-freeze crusts. The potential for fracture propagation is generally low, but in isolated places, especially on the shady slope, a prone-to-triggering combination of weak layer and snow slab cannot be ruled out.

Weather Forecast

On Wednesday, visibility will often be limited by dense clouds, with light and unproductive snowfall in places. The afternoon will bring a few clear spells, but the sky will only clear up more frequently towards the evening. The wind will be mostly weak from the west, in exposed high areas moderately strong with peaks around 30 km/h from the north-east. At 2000 metres around -14 degrees, at 3000 metres around -19 degrees.

Tendency

No significant change on Thursday, but freshening north-westerly winds may deposit fresh wind slab on a small scale.
