Watch out for fresh wind-blown snow!
In the Fatras and the Low Tatras, a low avalanche danger is declared, i.e. level 1 of the 5-part international scale. New wind-blown snow is deposited in east-facing moguls on a firm older surface. Unstable pillows and soft slabs are formed. Steep to extremely steep couloirs with slopes above 35° are a hazard. Small avalanches are likely to be triggered by large additional loads (e.g. foot traffic, skier falls, etc.).
The height of the snow cover above the forest line in Mala and Velika Fatra is around 20 to 40 cm, in the Low Tatras it is up to 80 cm of snow. During Friday about 10cm of new snow fell. The older snow cover is well bound due to the previous warming and cooling. The new snow is falling with steady wind and cooling, the northwest wind is depositing it again on mainly east facing slopes on a firm base, with which it does not bind well.
With snowfall forecast, a slightly increasing avalanche danger. By: Ivan Chlebovec
