Slightly increasing avalanche danger. Freshly generated drifts over small areas.
Avalanche danger continues to be low. The small amounts of fresh snow and small-sized snowdrift accumulations are often poorly bonded with the old snowpack surface. Triggering slides, small loose-snow avalanches and the drifts is possible through the loading of one sole skier. Apart from the risks of being buried in snow masses, the danger of being swept along and forced to take a fall need due consideration. The danger of small, in isolated cases medium-sized glide-snow avalanches is difficult to estimate. Caution urged 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.
Avalanche danger levels to increase further on Friday, due to fresh snowfall and wind
