Snowdrift accumulations are growing larger

Avalanche danger above the treeline is moderate, below that altitude danger is low. Main problem: freshly generated snowdrifts. Danger zones occur near ridges on N/E/S facing sloes, in gullies, bowls. Slab avalanches can be triggered by one sole person, releases usually small, the danger of falling outweighs that of being buried in snow. In addition, the fresh snow at 1400-1800 m becomes moist during the day and can slide/glide in extremely steep terrain. Mind the risks of taking a fall. Gliding snow is the main problem. On very steep slopes with smooth ground and grass-covered terrain and forest clearances, naturally triggered glide-snow avalanches are possible at any time of day or night. Avoid zones beneath glide cracks.

At high altitudes the fresh snow lies deposited atop a melt-freeze encrusted surface which is capable of bearing loads; in shady wind-quiet terrain atop soft layers. Due to westerly winds, the snow is being transported and small snowdrift accumulations have formed. Bonding to the old snowpack is inadequate. At lower altitudes the fresh snow is better bonded with the old snowpack surface. In the uppermost layers of the snowpack at high altitudes, isolated expansively metamorphosed layers are evident, otherwise the old snowpack is thoroughly wet down to the ground. Gliding movements on smooth slopes are the result. As temperatures rise the fresh snow and drifts become moist during the day, forfeit their firmness and can begin to slide over steep rocky ground.

As the weekend nears it will become sunnier and warmer. Wet-snow during the daytime will be the problem.
