Avoid zones below glide cracks, beware fresh drifts

Gliding snow activity will increase on Monday. Danger zones occur in all aspects up to 2400 m. Glide-snow avalanches can trigger anytime on steep grassy slopes and smooth rocky ground, and reach medium size. Avoid zones below glide cracks. Fresh snowdrifts will accumulate in summit zones and be difficult to recognize on Monday. Danger zones occur esp. on very steep shady slopes, releases mostly small-sized. Due to rain impact and mild temperatures, small wet-snow avalanches are possible on extremely steep slopes at low and intermediate altitudes.

Fresh snowdrift accumulations esp on shady high altitude slopes lie atop a loose snowpack and are prone to triggering there. On smooth ground (grass, rocks) which are steep enough, the entire snowpack can glide over the ground.

On Monday, visibility initially reduced due to fog and precipitation. Snowfall level at 1500 m, heavy showers will bring 10-20 cm of fresh snow at high altitudes by noon. Towards the end of this bout of precipitation, winds will slacken off, be blowing mostly at moderate strength from the west. In the afternoon, dry weather conditions. At 2000 m: -5 to 0 degrees; at 1000 m, 0 to +4 degrees, at 3000 m, -5 degrees.

Avalanche danger will not change.
