Avalanche Activity

Beware of wind-blown snow on all orientations. Soft, angular-grained snow in the northern sector.

In the High and Western Tatras there is a MODERATE, 2nd degree, avalanche danger in the morning and INCREASED, 3rd degree, avalanche danger in the afternoon. The avalanche danger will gradually spread to all orientations due to strong winds and snowfall. Snow slabs and pillows are expected to form, especially under rock walls, just below saddles, in couloirs and couloirs. Avalanche release at these locations will be possible with only a small additional load. Occasional medium-sized spontaneous avalanches are also expected. In the northern sector, soft, angular-grained snow remains an avalanche problem and is difficult to detect in the snow cover.

Snowpack Structure

Snow is expected throughout the day with very strong winds (above 20 m/s). The snow cover will therefore change rapidly and intensively. There will be alternating places where large amounts of snow (even more than 50 cm) will be piled up with places that will be blown into older hard ground, grass and rocks. Most of the snow is expected to be blown into the forest and slash belt. Due to the very cold air, this snow will not be able to bind with the base, which is made up of older snow or wind-blown slabs. Therefore, under the new snow, even under the older layer, a soft, angular-grained snow forms, which is very difficult to detect in the terrain. More than 30 cm of new snow is expected during the day.

Tendency

Due to wind, cold and snow rising.
