Rainfall will increase danger of wet-snow avalanches

Rainfall will increase danger of wet-snow avalanches

Following the rainfall yesterday and a night of partially cloudy skies, the snowpack can hardly freeze. The danger of wet-snow avalanches is heightened already in early morning and rises further due to daytime warming and solar radiation within the specified danger level over the course of the morning. Naturally triggered avalanches can be expected, most remain medium-sized. On steep, smooth-ground slopes with lots of snow which have not yet discharged, glide-snow avalanches can trigger in all aspects.

Due to reduced nocturnal longwave outgoing radiation and ongoing mild temperatures, the snowpack does not freeze at night. At all altitudes the snowpack is thoroughly wet.

Cloud cover in the latter part of the night will gradually withdraw, sunny weather will return, including rising temperatures. Convective cloud build-up in the afternoon will be minor. Towards evening, high-altitude clouds will move in. Temperature at 2000m: -1 to +8 degrees; at 3000m: -4 to 0 degrees. Light to moderate winds at high altitudes, in high alpine regions blowing at brisk strength from the west.

As a result of light foehn conditions and instable air, little change is anticipated. The slopes will continue to become bare of snow.
