Snowdrift accumulations are still prone to triggering with ascending altitude

Fresh and older snowdrift accumulations are still prone to triggering with ascending altitude. Danger zones occur esp. in steep terrain and in wind-loaded gullies and bowls. Avalanches can be triggered even by the weight of one sole skier and reach medium size. Higher daytime temperatures and solar radiation can cause naturally triggered small-to-medium glide snow avalanches and moist slides on very steep slopes. As precipitation sets in during the afternoon, avalanche danger levels will increase.

Due to solar radiation and higher daytime temperatures the snowpack is moist or wet up to high altitudes. During partly clear nights, a breakable crust (at high altitudes capable of bearing loads) forms which then softens during the daytime. Fresh snow has settled well and stabilised but is prone to triggering with ascending altitude, generally only by large additional loading

Nocturnal hours: dry and clear nighttime skies. Wednesday: dry until afternoon, a bit of sunshine in the morning, clouds will later move in from the north, rainfall will spread, snowfall above 1500 m, on Wednesday night down to 1000 m. At 2000 m: -1 degree. Light northerly winds.

The high-low pressure front on Thursday will halt the warm days temporarily. In the mountains it will become wintery again with noticeable amounts of fresh snow. Danger of dry-snow avalanches will again increase, danger of wet-snow avalanches will decrease.
