Considerable avalanche danger at higher altitudes
Avalanche danger is considerable above 1800m, moderate below that altitude. The main problem is the fresh fallen and drifted snow. One single winter sports enthusiast can trigger small-to-medium sized slab avalanches in wind-loaded zones, particularly on steep NW-E-SE facing slopes and in gullies and bowls. In zones with rain impact, increasingly frequent wet snowslides and avalanches will also be possible during the course of the day.
The large amounts of fresh fallen snow from Saturday night were able to settle somewhat and slightly consolidate. The fresh snow and fresh snowdrifts since Thursday often lie deposited on top oa a loosely-packed, faceted, expansively metamorphosed old snowpack surface or atop surface hoar. Thus, bonding is poor. In addition, layers inside the fresh snow and freshly generated drifts are also poorly bonded.
Nocturnal hours: heavy, intense snowfall down to low altitudes. Sunday: impeded visibility due to low lying clouds and snowfall. Later on, it will become drier, clouds will disperse somewhat. Temperature at 2000m: -11 degrees; at 3000m: -17 degreres. Moderate to strong-velocity northerly winds at high altitudes.
Avalanche danger receding only slowly
