Avalanche Activity

Watch out for new wind-blown snow at the highest elevations and wet snow in the mid-elevations!

The weather during Tuesday will be influenced by the edge of a pressure low. This will bring cooling from the northwest and precipitation, which will have a snowy character from 1200 m above sea level. In the High, Western Tatras the second degree of avalanche danger persists - moderate. The main avalanche problem will be wind-blown snow at the highest altitudes. Due to the change of the flow to northwest, the exposure of the most dangerous places to the south, southeast and east will change. Thus, in the gullies of the highest altitudes with a high gradient, situated on the leeward sides of the ridges, it will be possible to find wind-rolled slabs and pillows of unstable snow, which can be loosened, especially by large additional loads. At mid-elevations, rain reduces stability by intensively soaking the snow cover, so the second avalanche problem (below 1500 m) is wet snow. Avalanches from wet snow or foundation avalanches from wet snow may occur, especially on slopes with visible gullies.

Snowpack Structure

The warm February weather has meant that snow cover is absent at lower elevations. Above it, there is a firn snow cover in the mid-altitudes, which is, however, intensively waterlogged by rain and positive temperatures. Gullies have formed in a number of places, triggering basal avalanches in many places. This situation will persist for the next few days. Dry snow is only found at the highest elevations of the mountains and has been transported by the wind to the leeward sides of the mountains in slabs and pillows. Such formations lie on a layer of old firn with which they are not sufficiently bound.
