Fresh snow and snowdrifts with ascending altitude prone to triggering

Fresh fallen snow are increasingly prone to triggering with ascending altitude, can be triggered as a slab or a loose-snow avalanche even by one sole skier, esp. near ridgelines and in wind-loaded gullies and bowls. Frequency and size of danger zones increase during the day, and with ascending altitude. Naturally triggered: small slides and loose-snow avalanches in very steep terrain.

In the coming 24 hours there will be 20-25 cm of fresh snow registered, often amid wind-impact. Fresh snow and drifts will be prone to triggering, lie deposited atop a mostly compact old snowpack surface, bonding well lately and stabilizing.

Nocturnal hours: gray nighttime skies, rainfall and snowfall will be heavy, snowfall level mostly at 700-1000 m. Sunday: wintery again, reduced visibility, heavy clouds, snowfall, heavy in the morning hours, slackening off in the afternoon, then again intensifying in the evening. Cold. At 2000 m: -3 degrees. Initially brisk northerly winds, later easing.

Still uncertain how much fresh snow will arrive on Sunday night, perhaps lots. Avalanche danger remains tense.
