They are found in ridgeline terrain, in gullies and bowls in N-SE aspects, where slab avalanches can be triggered by large (in isolated cases by minimum) additional loading. In steep rocky terrain, naturally triggered releases are possible. In addition, on steep grass-covered slopes, glide-snow slides can trigger. The amounts of fresh snow from the last few days have been able to settle. Frequencly, windblowin zones alternate with wind-loaded zones over smallest spaces. Isolated older snowddrift accumulations have been deposited atop a compact old snowpack surface. Weak layers (loose embedded snow) occur primarily inside the latest layer of fresh snow, in isolated cases in transitions to the old snowpack. Overnight, a crust of varying thickness forms, or else surface hoar. The snow is becoming heavier, it is still loose only in isolated cases. In spite of cloud cover, the powerful diffuse radiation is reinforcing the settling of the snowpack. At lower altitudes the recent layer is being further moistened. A lubricating layer at ground level enhances gliding snow. Following a night of frequently clear skies, low lying cloud will move in from the northeast on Saturday, and persist all day long. It will remain largely dry, only in the northern regions might there be a small amount of snowfall. The NW winds will be light-to-moderate. Midday temperatures at 2000 m: -6 degrees; at 1500 m, -2 degrees Gray skies also on Sunday. No significant change in avalanche danger is expected to start with. 2021-04-16T16:00:00+00:00 avalanche-warnings.eu 2021-04-16T22:00:00+00:00 2021-04-17T22:00:00+00:00 1 drifting snow older ridgeline snowdrift patches Low avalanche danger At high altitudes there are still isolated avalanche prone locations in the form of older snowdrift patches.
