Considerable avalanche danger at higher altitudes
Considerable avalanche danger at higher altitudes
Avalanche danger is considerable above 1800m, moderate below that altitude. The main problem is the 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 be possible during the course of the day. Also gliding snow activity is increasing again.
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, often with surface hoar, 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 has been weakened in places by rain impact.
Tuesday will be dry, with sunshine and high-altitude cloudbanks. Warmer temperatures will continue in the mountains. At 2000m: 1-5 degrees; at 3000m: -4 degrees. Initially brisk westerly-to-southwesterly winds at high altitudes, slackening off later on in the day.
Avalanche danger receding only slowly
