Watch out for wind-blown snow that has created unstable snow slabs and pillows.
In Veľká Fatra and Lúčanská Mala Fatra there is a MODERATE avalanche danger, 2nd degree. Due to snowfall and strong winds, snow slabs and pillows have formed over the forest belt, which are wound up on the older, mostly wind-blown surface. New snow is an avalanche problem in the forest belt. Avalanche will be able to be released especially with large additional loads in steep terrain. Watch out for places that form a terrain trap. Exceptionally, small spontaneous avalanches may form in steep forest terrain from new loose snow.
Due to snowfall combined with very strong winds (above 20 m/s), the snow cover changed very quickly, especially over the forest belt. Places where large amounts of snow (even more than 30 cm) are piled up alternate with places that are blown into older hard ground, grass and rocks. Most of the snow is blown into the forest and slash zone. Due to the very cold air, this snow is unable to bind with the substrate, which consists of older snow or wind-blown slabs.
