Snow Cover

No snowdrift Storm slab (soft slab) Dry Det er mer nysnø vest i regionen. Her i Raulansdområdet er det mye avblåst i høyden, og fokksnø av vekslende hardhet i østlige sider. Men det finnes løssnø i skogen og enkelte renner der vinden ikke har tatt.

Avalanche Danger Assessment

2 Moderate Stabile forhold i Raulandsområdet akkurat nå. Den nye fokksnøen er rimelig stabil og det er ingen skred å observere. Vær likevel obs i bratte sider og heng der fokksnøen ligger oppå harde og glatte skarelag Det er meldt litt snø og vind som kan føre til ustabil fokksnø i høyden. Etter på skal det bli en del sol som kan føre til våte løssnøskred enkelte steder. Forecast correct
