Slight rise in danger of wet-snow avalanches during daytime hours

Slight rise in danger of wet-snow avalanches during daytime hours

Avalanche danger is LOW. Danger zones for dry slab avalanches do not threaten. Due to solar radiation and warmth, danger of wet avalanches rises somewhat during the daytime. On extremely steep (>40°) sunny slopes (E/S/W) small to medium naturally triggered wet loose-snow avalanches are possible.

Due to warmth and direct or diffuse solar radiation the snowdrifts have settled and consolidated. Only in high alpine shady terrain is the bonding still insufficient. Deep down in the snowpack above 2200 m there are faceted layers. The snowpack was moistened in all aspected up to 2200 m on Friday, on sunny slopes up to summit level. During the night of only partially clear skies the outgoing radiation will be reduced, the melt-freeze crust which forms will not be able to bear loads. It will soften up on Saturday. On steep sunny slopes it is wet down to the ground, on west-facing slopes it will become isotherm for the first time on Saturday, down to the ground. Due to wetness the snowpack loses its firmness. Weak layers are weakened further still. Also, free flowing water at ground level increases the gliding movement.

Sunny weather all day long, light to moderate winds. At 2000m: 4 degrees; at 3000 m: -1 degree.

No change is expected.
