As a result of snowfall, likelihood of slab avalanches triggering increasing, esp. in ridgline NW/N/NE facing slopes above 2000m. Avalanches can be triggered by persons and reach medium size, esp. by large additional loading.
Snowpack
dp.1: deep persistent weak layer
5-10cm of fresh snow is anticipated, locally more. Fresh snow and freshly generated snowdrifts lie deposited on W/N/W facing slopes above 2200m atop a weak old snowpack surface. The old snowpack is expansively metamorphosed with a loosely-packed surface of surface hoar and faceted crystals. South-facing slopes below 2000m: fresh snow and drifts are being deposited atop a crust.
