Overall little snow on the ground, low avalanche danger

Overall little snow on the ground, low avalanche danger

Avalanche danger is generally low. Main problem: superficial layers in wind-impacted steep terrain, in wind-loaded gullies and bowls and behind abrupt discontinuities in the terrain are often still prone to triggering. Small-to-medium sized slab avalanches can trigger even from one sole skier on isolated E/N/SW facing slopes and in wind-loaded gullies and bowls. Avalanche releases are generally small-sized. The risks of taking a fall outweigh those of being buried in snow masses.

The shallow snowpack has settled well in general and is low in internal tension. On shady slopes the snow is still powdery, often there is surface hoar. On sunny slopes there are melt-freeze encrusted layers. Only on high altitude steep ridgelines slopes have the small trigger-sensitive snowdrift accumulations persisted.

Nocturnal hours: high fog will extend to nearly 1800 m, beneath that altitude the outgoing radiation will be reduced.. Above the fog, dry air and clear skies, thus, good outgoing radiation. Friday: at 1500-1800 m, reduced visibility due to fog, possibly light snowfall. In high alpine regions, initially sunny and dry conditions. In the afternoon, fog could move in at high altitudes. Icy-cold winds in the ridgelines. At 2000 m: -10 degrees. Light to moderate NE winds.

Tenacious high fogbanks up to nearly 2000 m. Above that, sunshine. Avalanche danger levels are not expected to change significantly.
