Moderate avalanche danger at higher altitudes
Older and small-sized freshly generated snowdrift accumulations are often still prone to triggering at high altitudes. Winter sports enthusiasts can trigger small-to-medium sized slab avalanches in wind-loaded zones, particularly on steep W-E-SE facing slopes and in gullies and bowls. At lower altitudes, wet snowslides and small avalanches will be possible.
The fresh fallen snow and drifts from the most recent period of precipitation have settled further as a result of higher temperatures. Bonding to the often loosely-packed, faceted, expansively metamorphosed old snowpack surface, and inside the unfavorably structured layers of the old snow, continues to be moderate-to-poor in places. In addition, layers inside the recent fresh snow and drifts are often still prone to triggering. Up to intermediate altitudes the snowpack surface is frequently melt-freeze encrusted. At low altitudes there is little snow on the ground.
Thursday will begin with widely dispersed layers of clouds. During the morning hours, the cloud cover will recede to the east and a few hours of sunshine can be expected. Temperature at 2000m: +1 degree; at 3000m: -6 degrees. Moderate-strength southwesterly winds at high altitude, with some foehn-wind impact.
No significant change is anticipated.
