Werdenfels Alps

As the temperature rises during the day, the risk of avalanches increases considerably at higher altitudes.

As the temperature rises during the day, the risk of avalanches increases considerably at higher altitudes.

The avalanche danger above 1400 m increases from moderate to considerable during the daytime changes. Below that it is low. In the morning, gliding snow is the main problem at medium altitudes. Small and medium-sized gliding avalanches spontaneously release themselves on a few steep slopes with smooth ground. Staying under glide cracks should be avoided.

When the sun shines, the activity of sliding snow increases on sunny slopes and wet loose snow avalanches of up to medium size can be expected from extremely steep terrain.

In addition, weak persistent layers above 1500 metres are problematic. With large additional loads, large slab avalanches can also be triggered in isolated cases in the west, north and east aspects. Take particular care in transition areas from a little to a lot of snow.

Last week's heavy 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. Up to high altitudes, the snowpack is otherwise slightly moist; at medium altitudes, it is 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.
