Watch for snow pillows on the leeward (N-SW) sides of the mountains and snow accumulation during the day on the S sides.
In the High , Western and western part of the Low Tatras it is valid at the highest altitudes - from 1700 m above sea level. MODERATE avalanche danger (i.e. 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. Avalanches can be triggered locally, especially by 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, which will reduce its stability. During the day, small spontaneous avalanches may occur sporadically here (S exposures), mostly from wet snow.
The weather during Monday will be influenced by a pressure high, during the day we expect bright sunny weather and gradual cooling. Snow from the last period of snowfall has been blown by strong winds into valleys, windward sides are often blown to the base, 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 in the steepest elevations a crust or layer of firn is formed on the surface. During the day, the snow will become wetter and packed on the S slopes due to warming. The total snow cover is still below average. In the morning, the surface of the snow cover will be hard, especially at mid-elevations and positions exposed to sunlight during the previous day.
With alternating temperatures decreasing.
