Avalanche Activity

Beware of wind-blown snow pillows!

In the high altitudes (above 2000 m above sea level) of the High Tatras there is still a moderate avalanche danger (2nd degree from the 5-part international scale). The danger is mainly posed by the leeward sides of ridges, steep to extremely steep couloirs (slope above 35°), where strong westerly winds have transported large amounts of snow. Snow pillows and slabs are found in these places, the stability of which is difficult to assess. Their loosening is possible, especially under high additional loads (e.g. foot traffic, skier's fall, etc.). Moderate avalanches can also occur. At lower altitudes, the snow cover has stabilised due to the previous warming and subsequent cooling. Avalanche danger increases with altitude.

Snowpack Structure

In the High and Western Tatras, the snow cover ranges from 40 to 80 cm from the middle altitudes. The snow is very unevenly distributed due to the wind, on the windward sides it is blown down to the base, and on the leeward slopes (mainly eastern orientations) there are snow pillows and slabs of unbound snow. At altitudes below 2000 m a.s.l., a brief warming (Tuesday) and subsequent cooling (Wednesday) produced a hard crust on the snow surface, which has a stabilising effect on the snow profile. However, the snow surface is not supportable for pedestrian movement in most places, it is breaking.

Tendency

Steady during Thursday, increasing on Friday with snow and wind.
