Wet-snow avalanches increasingly likely to trigger during daytime + moderate snowdrift problem on extremely steep shady slopes

Avalanche danger is moderate above 2600m in the morning, danger below that altitude is low. During the course of the morning it rises to MODERATE at all altitudes. Due to solar radiation and warmth, the snowpack becomes increasingly moist, and naturally triggerd wet-snow avalanche activity increases during the course of the day, releases sometimes medium. In isolated cases wet snow avalanches can be triggered by 1 person, esp. in very steep (>35°) terrain. Above 2600 m dry-snow slab avalanches can be triggered in a few places by 1 person, esp. on extremely steep (>40°) shady slopes, releases can reach medium size. Below 2600 m where the snow is sufficient, naturally triggered glide-snow avalanches can be expected on steep slopes, particularly where the recent fresh snow fell on bare ground. Avoid zones below glide cracks.

Solar radiation makes the snowpack wet, it loses its firmness. On steep rocky slopes which have again been snow on and grassy slopes, the snowpack is wet down to the ground and can glide away. The recent fresh fallen snow is quickly diminishing due to melting. During the night a melt-freeze crust capable of bearing loads often forms, but later softens rapidly. On north-facing slopes there are often breakable crusts. On sufficiently steep north-facing slopes above 2400 m there is also some powder to be found.

Sunday night skies will be mostly clear but for a few clouds and Sahara dust reducing outgoing radiation somewhat. Winds only on the Main Alpine Ridge (40 km/hr). On Monday, sunshine from morning til night, a few clouds, some Sahara dust, but good visibility. The southerly winds will be brisk (60 km/hr). At 2000 m: from 4 rising to 9 degrees. On Monday night, clear skies, brisk southerly winds.

Classic springtime will continue, the snowdrifts will rapidly stabilize.
