Pay close heed to snowdrifts at high altitudes
Fresh drifts are still trigger-prone at high altitude and on steep shady slopes. A small-to-medium slab and in steep terrain also loose-snow avalanche can be triggered by 1 person. Such danger zones will increase with ascending altitude. Snowdrift masses in steep terrain should be avoided. On very steep and rocky slopes, slides and loose-snow avalanches can be expected during the course of the day due to solar radiation. Glide-snow avalanches can trigger at any time of day or night and grow to medium size in zones where snowfall has been heavy. Caution below glide-cracks.
Due to persistent southerly foehn wind, fresh snowdrift accumulations have been generated ongoingly, deposited atop a soft sufrace and often atop surface hoar, esp. on shady slopes at high altitudes. Bonding is often poor-to-moderate. The old snowpack is compact and stable, shows stark impact from wind. A low and intermediate altitudes the snowpack is wet down to the ground. On sunny slopes a breakable crust forms at night.
Nocturnal hours: Snowfall above 1200 m, then dry weather with residual clouds. Monday daytime: Quite sunny in many regions, cloud cover later on will increase, minor snow showers above 1300 m can be expected. At 2000 m: -2 degrees. Light winds at all altitudes.
Slight perturbances will increase cloud cover on Tuesday, light-to-moderate snowfall amid brisk westerly winds. Danger of dry-snow avalanches will increase somewhat, depending on the amount of fresh snowfall.
