Heed snowdrift accumulations increasingly in high altitude terrain

Heed snowdrift accumulations increasingly in high altitude terrain

Low avalanche danger prevails, moderate danger at high altitudes. With ascending altitude the snowdrifts on shady slopes in particular and in wind-protected, ridgeline terrain, as well as behind abrupt discontinuities in the terrain, are prone to triggering. Size and spread of the danger zones will increase as the day unfolds. Small to medium avalanche triggerings are possible from winter sports enthusiasts. Naturally triggered slides and small loose-snow avalanches are also possible on very steep slopes and heavily wind-loaded zones.

By Monday evening, up to 20-25 cm of fresh snow is expected. At high altitudes it will be transported. Fresh snow and freshly generated snowdrifts are prone to triggering. They lie deposited atop soft layers or melt-freeze encrusted surfaces. Bonding worsens with ascending altitude. Below 1800 m the snow is often falling on bare ground.

Nocturnal hours: starting at midnight, light rainfall/snowfall will set in. The snowfall level will descend initially from 1800 down to nearly 900 m. Monday: a cold front will bring some fresh snowfall. Behind the front the precipitation will slacken off. Clouds will remain heavy for most of the day, visibility correspondingly poor. Temperature at 2000 m: descending from -3 to -6 degrees. Strong and gusty NW winds.

On Tuesday, snowfall down to low lying areas. During the daytime hours weather conditions will calm, a bit of sunshine is anticipated. It will remain cold and windy. Avalanche danger levels could increase again.
