Avalanche Danger Assessment

1 Low Stort sett stabile forhold i fjellet nå. Våt løssnø under ca 1000moh kan føre til enkelte våte løssnøskred. Fra ca 1500moh og oppover kan det finnes ustabil fokksnø i nordvendte heng. Det er meldt litt kaldere vær neste døgn,dette vil redusere faren for våte løssnøskred.
