Advice

Snow cover (in Norwegian)

Fra tidlig denne uka har vinden stått på i regionen og flyttet snø inn i nordøst- og østvendte heng. Før vinden begynte å ta var det mye løssnø vest i regionen. Observatør melder om 30-45 cm nysnø de siste dagene. Natt til søndag ventes mildvær å ha fuktet snøoverflaten til ca 300 moh.

Lørdag ble det fjernutløst skred rundt skoggrensen. Dette har trolig gått på kantkorn i nedre del av snøpakken. Søndag var det flere store naturlig utløste skred i Tamokdalen.

Fredag er det observert flere drønn i snøen i regionen.
