Increasing wet snow problem due the course of the day

Increasing wet snow problem due the course of the day

The avalanche danger is low in the morning but increases to moderate during the course of the day. Danger of small to medium sized wet loose-Snow avalanches on steep sunny slopes due to warming and radiation. These can trigger spontaneously or by individuals. On steep grassy or forest slopes gliding snow avalanches can trigger spontaneously. Slab avalanches are possible in some places in shady steep slopes in high altitudes.

due to the mild temperatures and the strong radiation the snow cover could settle. During the night surface hoar is forming which will quickly soften during the day. The snow cover is moist up to high altitudes and looses it’s strength and bonding. The whole snow cover could begin to glide especially on bare soils. Weak layers which are prone to triggering are only found in high altitudes on shady slopes within the old snow cover (Graupel, soft crystals).

Thursday night will be clear. Friday predominantly sunny and mild mountain weather. In the eastern half of Styria some cumulus clouds. Moderate to northeasterly to easterly winds. Temperatures in 2.000 m at noon are around +4 degrees and in 1.500 m +8 degrees.

Friday night will be clear. Saturday morning clouds are coming from north but don’t cause much precipitation. Northerly winds get stronger. Avalanche danger decreases a little bit.
