Persistent weak layers· Morning
- Above 1,500 m
The risk of avalanches increases with the amount of sunlight.
The risk of avalanches increases with the amount of sunlight.
The avalanche risk is moderate above 1500 metres and low below that. Gliding snow and wet snow will become the main problem during the day changes. Overnight and in the mornings, small and medium-sized gliding avalanches occasionally release themselves on steep slopes with a smooth surface. Sliding snow activity increases with the sunlight and wet loose snow avalanches of up to medium size can then be expected from extremely steep terrain.
In addition, weak persistent layers above 1500 metres are problematic. With a large additional load, medium-sized slab avalanches can be triggered in the west, north and east aspects. Take particular care in transition areas from a little to a lot of snow.
Last week's snow lies on a weak old snow foundation at higher altitudes. It freezes on the surface overnight and is usually stable, but softens again quickly in the sun during the day. Moisture penetration then progresses. The snowpack is usually slightly damp, sometimes completely soaked to the ground. In shady slopes at higher altitudes, faceted crystals can be found deeper in the snowpack.
Still spring conditions with included persistent weak layer problem.
