For the Fatra Mountains and the eastern part of the Low Tatras there is a moderate avalanche danger, i.e. 2 degree from the five-part international scale. This danger is due to the progression of the frontal system and moist warm air, which will bring heavy precipitation at high altitudes associated with extremely strong winds. The main avalanche problem at the highest altitudes is wind-blown snow (in E, SE, S and SW orientations) and wet snow (below 1500 m). High snowfall thresholds mean that intensive snow cover growth is not predicted for these regions. However, intense rain during the day will have a destabilising effect on the snow profile.
The old snow cover melted and froze due to the weekend warming and subsequent cooling. A thick crust of icy snow has formed on the surface. Snowfall is expected only at the highest elevations of these mountains, where the wind blows it to the leeward sides of the mountains. Here there are snow pillows and slabs of wind-blown new snow lying on top of the old hardened cover. Overall, the snow cover has become sooty and wet as a result of the warming. Precipitation is expected to continue during the day and, with the exception of the highest elevations, the snow cover will be soaked.
