Slightly increasing avalanche danger levels due to fresh snowfall and newly generated drifts

Slightly increasing avalanche danger levels due to fresh snowfall and newly generated drifts

On Thursday avalanche danger levels will increase to moderate. Fresh snow and newly generated drifts will increase in frequency with ascending altitude, often poorly bonded with the snowpack surface. Triggerings of small-to-medium loose-snow and slab avalanches are possible by the loading of one sole skier. Apart from the risks of being buried in snow masses, the dangers of being swept along and forced to take a fall need adequate consideration. The danger of small, in isolated cases medium-sized glide-snow avalanches continues to be difficult to assess, for that reason avoid zones below glide cracks.

By Thursday evening, 10-20 cm of fresh snow is expected, deposited atop a well-consolidated old snowpack. On wind-protected shady slopes the fresh snow will blanket the powdery layers, often a breakable or non-breakable wind crust and on steep sunny slopes a melt-freeze crust. In ridgeline and pass areas, fresh snowdrifts will be generated over small areas under the impact of intermittently strong-velocity winds.

Nocturnal skies will be cloudy, with light snow showers above 1600m. On Thursday in the northern regions, limited visibility and fog. Further to the south, rain, snowfall and dropping temperatures in the afternoon hours, as winds intensify. The snowfall level will sink from 1400 to below 1000m. At 2000m: -2 degrees during the daytime. Moderate to brisk westerly winds at high altitudes.
