Beware of wind-blown snow that forms unstable snow slabs and pillows. Underneath are soft, angular-grained snow.
In the Low Tatras there is a moderate avalanche danger, 2nd degree. Due to strong winds and snowfall, the danger has gradually spread to all orientations. Snow slabs and cushions have formed, especially under rock walls, just below saddles, in couloirs and moguls. Avalanche release in these places is possible, especially with high additional loads. Occasionally, small spontaneous avalanches may occur, mainly from new snow. In the northern sector, soft, angular-grained snow remains an avalanche problem and is difficult to detect in the snow cover.
Due to snowfall combined with very strong winds (above 20 m/s), the snow cover changed very quickly. 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. Therefore, under the new snow, even under the older layer, a soft, angular-grained snow is formed, which is very difficult to detect in the terrain.
