Wet-snow, glide-snow avalanches due to warmth and solar radiation
Friday will bring precipitation by midday, temperatures will drop, avalanche danger could increase. Danger of wet-snow and glide-snow avalanches must still be heeded, esp. in regions with rain impact.
Wet-snow, glide-snow avalanches due to warmth and solar radiation
Avalanche danger is low in the morning, rises rapidly during the daytime hours. In extremely steep E/S/W facing terrain, isolated small avalanches are triggerable naturally. On very steep slopes, medium avalanches are possible on steep smooth ground. On steep smooth slopes, in addition, small-to-medium glide snow avalanches are possible. Glide cracks are indicators of imminent danger. Heed the risks of being forced to take a fall.
The snowpack is thoroughly wet up well into intermediate altitude terrain, and wet down to the ground. Variably cloudy skies on Monday night will generated a melt-freeze crust, sometimes capable of bearing loads, which softens up during the daytime on Tuesday, making the snowpack lose its firmness, and wet-snow / glide-snow avalanches possible in steep terrain. At high altitudes, older snowdrift accumulations have soft layers embedded, which are unlikely to trigger. Below 1500m on shady slopes there is not much snow on the ground.
Nocturnal hours: scattered clouds in the early part of the night, then becoming denser, but it will remain dry. Thursday: cloud layers widespread, hampering the sunshine, shading it during the afternoon. It will remain dry, zero-degree level at 2700m. At 2000 m: 1-6 degrees. Brisk to strong W/SW winds.
