Main problem: trigger-sensitive intermediate layers at ground-level in the old snow. Isolated slab avalanches can be triggered on shady steep slopes be large additional loading, particularly where the snow is shallow, i.e. at entries to gullies and bowls, particularly in places where there is relatively shallow snow compared to the immediate vicinity, i.e. at entries to gullies and bowls. Triggered avalanches can be of small-to-medium size.

Melt-freeze encrusted surfaces (hard as steel, icy, breakable, snowdrift patches, melt-freeze from the rain) dominate. Inside the snowpack the recent layers are relatively well bonded. A potential trigger-sensitive layer of faceted and soft snow is at high altitudes. Current stability tests show that the tendency towards fracture propagation is minimal, at least over surface-wide areas.

On Friday skies will be cloudy in the Northern Alps, but initially it will remain dry. During the afternoon light rainfall will set in, snowfall above about 1500 m. In inneralpine regions some sunshine is expected above the valley fog; during the afternoon light conditions will become diffuse. Strong S/W winds, later northwesterly in exposed terrain above the treeline blowing at 40-60 km/hr. At 2000 m: 0 degrees; at 3000 m: -4 degrees. On Saturday, lots of cloud, visibility generally adequate, the inneralpine mountain massifs have somewhat better conditions. During the course of the day, sunshine may come through. Winds will not be disturbing, at most blowing at moderate strength. Temperatures will remain mild.

No significant change initially
