Watch for snow pillows on the leeward (N-SW) sides of mountains and wet snow on sunlit slopes during the day.
In the High, Western and central part of the Low Tatras it lasts at the highest altitudes - above 1700 m above sea level. MODERATE avalanche danger (2nd degree of the 5-part scale). Significant snowfalls from the last snowfall period were often blown by strong winds up to the forest zone. However, on the leeward sides of the mountains (mainly W, NW and N), snow pillows and slabs are locally formed by the wind at the highest elevations, and their stability may be low, especially on steep to very steep shaded slopes. Occasionally, it is possible to release an avalanche, especially with large additional loads. At mid-altitudes the snow has settled and stabilised due to the temperature change. During the day, on sun-facing south-facing slopes, it will gradually become heavier, reducing its stability, and small spontaneous avalanches may occur sporadically, mainly from moist to wet snow.
The weather over the next few days will be influenced by a weakening pressure high, during which sunny weather will continue. Snow from the last snowfall period has been blown by strong winds into the valleys, windward sides are often blown down to bedrock, but locally it may be deposited on the W, NW and S exposures of the mountains in the form of smaller pillows and slabs. At the highest elevations of the predominantly N exposures it retains a dusty character, while at the steeper elevations a crust or layer of firn is formed on the surface. During the day, the snow will become wet and melt due to warming on the southern slopes; at night and in the morning these areas will be hard to icy. The overall snow cover is still below average.
With the change of temperature slightly decreasing.
