Moderate avalanche danger due to glide-snow avalanches: heed glide cracks. Isolated weak snowpack layers.

Avalanche danger is moderate up to 2600 m, below that altitude danger is low. Glide-snow avalanche activity is increasing due to wetness of the snowpack. In zones which have not yet discharged on steep grassy slopes in all aspects, glide-snow avalanches can trigger, reach medium size, sometimes large size. Avoid zones below glide cracks. In few danger zones above 2400 m on sunny slopes there are weak layers in the uppermost part of the snowpack, triggerable by large additional loading, releases medium, occasionally large-sized. Acute danger of falling.

The snowpack is compact and thoroughly wet up to 2000 m, on sunny slopes up to 2600 m, wet down to the ground. On shady slopes above 2200 m, older snowdrift patches lie atop loose snowpack layers with near-surface faceted crystals, only seldom triggerable. Moistened snowpack forfeits its firmness. Latent danger of glide-snow avalanches on steep slopes on smooth ground. During the night a melt-freeze crust forms, then softens and the snowpack forfeits its firmness.

On Tuesday frequent sunshine, local fogbanks can reduce visibility. Cirrus clouds will pass through, hamper the sunshine somewhat,create diffuse light. Brisk to strong westerly winds. At 1500 m: 0-8 degrees; at 2000 m: 2-5 degrees; at 3000 m: -4 degrees.

The gliding snow problem will persist. Mild temperatures and lots of sunshine will make the snowpack wetter. Avalanche danger levels are not expected to change significantly.
