Persistent weak layers
- Above 1,900 m
Low avalanche danger, but still isolated avalanche prone locations in the persistent weak layer!
On the surface, older wind slab snow can be found in places, which is usually sufficiently connected to the old snowpack. The snow base, fundament is often stable. Only in shady high altitudes does floating snow (cup crystals) continue to weaken the snow layering in places.
Low avalanche danger, but still isolated avalanche prone locations in the persistent weak layer!
The avalanche risk is generally low. Nevertheless, there are individual avalanche prone locations, in particular behind terrain edges and in entrances to higher, steep, shady gullies and bowls. Small to medium-sized slab avalanches can occasionally be triggered by individuals.
The isolated snow showers will subside on Tuesday night and the clouds will soften again. Tuesday will bring mostly dry and occasionally sunny mountain weather. However, it will not be unclouded, initially low residual clouds may persist in the northern Alps and in the afternoon some cumulus clouds or medium-high cloud fields will form. The peaks may then be temporarily shrouded in fog. The temperature at 2000 metres will be between -5 and 0 degrees north of the main Alpine ridge and between -3 and +2 south of it. At an altitude of 1500 metres, the temperature will be between -1 and +6 degrees. Moderate to brisk winds from north-west to north.
On Wednesday, it will once again be sunny and largely dry, with temperatures rising slightly. Until then, the risk of avalanches will decrease slightly. From Thursday, a massive onset of winter and an increase in avalanche risk is to be expected!
