Wet-snow activity increases already in early morning

Avalanche danger is MODERATE. Due to solar radiation, increasing wet-snow activity is expected during the daytime. Beginning on extremely steep slopes (>40°) in southern and eastern aspects, it will then spread to all aspects, releases small-to-medium. also triggerable by 1 person. 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. Above 3000 m, dry slab avalanches can be triggered in a few places by 1 person, esp. on extremely steep (>40°) shady slopes, releases mostly small.

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, possibly sweeping the old snowpack along if it becomes wetter. The recent fresh fallen snow (often lying atop a layer of Sahara dust, the wet loose-snow avalanches glide over this crust) is quickly diminishing due to melting. During the night a melt-freeze crust sometimes forms, but later softens rapidly.

Nighttime skies will be foehn driven by strong S/SE winds (80-90 km/hr), good visibility except on Main Alpine Ridge. Often very warm. Wednesday will by dry, good visibility, foehn-driven winds. In the latter part of the day, high-altitude clouds will move in, visibility become diffuse. More clouds and some minor showers on the Main Alpine Ridge. The SE winds will be moderate. At 2000 m: 6-10 degrees; at 3000 m: -1 to +2 degrees.

Classic springtime will continue.
