Rapid daytime rise in avalanche danger
The old snowpack is generally well consolidated and compact during the morning hours. At lower altitudes, however, the mild temperatures and solar radiation is making the snowpack thoroughly wet, rapidly leading to a loss of firmness. At higher altitudes, older snowdrift accumulations are frequently still prone to triggering.
After a night of partially cloudy skies, sunny mountain weather with only a few cloudbanks in high altitudes, and convective cloud build-up during the afternoon. It is expected to be even milder than on previous days. Temperature at 2000m: from 2 to 8 degrees; at 3000m: -1 to -1 degree. Brisk westerly winds at high altitude.
The danger of wet-snow avalanches increases during the course of each day.
Rapid daytime rise in avalanche danger
In early morning, danger is moderate. Isolated danger zones for slab releases occur in steep ridgeline terrain, behind sharp drops in the landscape, in wind-loaded gullies and bowls. Avalanche danger swiftly and steeply rises due to solar radiation and mild temperatures. In very steep terrain in all aspects, wet-snow slides and avalanches are possible due to solar radiation and daytime warming. On steep grass-covered slopes, gliding snow activity is gradually increasing. Caution below glide cracks in the surface of the snowpack.
