Slightly increasing wet-snow avalanche danger during the course of the day

Slightly increasing wet-snow avalanche danger during the course of the day

The avalanche danger is low and increases slightly during the course of the day. Due to warming and sun radiation predominantly small, sometimes medium sized wet loose-snow avalanches can trigger. Danger spots are found especially in full, steep gullies and slopes of all expositions. Weak layers within the old snow can be triggered only by high additional loads in extremely steep shady slopes and lead to dry slab avalanches.

The snow cover can settle during the night. During the day the snow cover which is wet till the base, softens and loses its stability. In steep shady slopes weak layers of faceted snow are found within the snow base.

Thursday night will be without precipitation with few clouds. Friday morning will be predominantly in southeastern parts already cloudy. The foothills are foggy and partially rain showers from noon on. Then the fog spreads into the central and northern Alps. The longest sunshine will be in Totes Gebirge. Moderate to brisk northeasterly winds. Temperatures at noon will be around 1 to 3 degrees in 2.000 m.

Friday night the weather is changing. The snowline is 1.200 m in the north and 1.500 m in the south and 10-30 cm new snow is expected. The most will be in Nordstau areas. Visibility will be poor. Northerly winds which are increasing during the day. The avalanche danger increases with altitude.
