Moderate avalanche danger in high altitudes - snowdrift is prone to triggering
Avalanche danger above 1.800 m is moderate. Danger spots are located in very steep entries, gullies and behind ridgelines in the expositions north to east. There slab avalanches can be triggered by small additional loads cannot be ruled out.
The snow base can settle and is mostly stable. Only in high altitudes the surface is still powder-like in some places. The new snowdrift is partially placed on top of soft layers, partially on top of a hard, icy old snow cover and is not sufficiently bonding. In general the snow cover is distributed unevenly and wet in medium altitudes. Blown-off areas are often hard and icy.
A high low pressure system above Poland is about to weaken, but in the lower levels is still wet and unstable layered cool air masses. Saturday will be dominated by low altitude clouds which can cause some snofall. The snowline ist between 600 and 1.200 m. In the afternoon the cluds can clear up. Weak northern winds. Temperatures at noon are around -7degrees in 2.000 m and around -2 degrees in 1.500m. Saturday night it will clear up and in the morning it will be sunny. The whole next week will be dominated by high pressure, increasing temperatures and sunny weather.
The snowdrift danger and the avalanche danger are decreasing.
