Snow cover (in Norwegian)

Wednesday 7. April 2021

Der vinden har tatt er det fokksnø av varierende hardhet i overflaten, ellers myke flak og løs snø i skjermet terreng.
Forrige uke var preget av mildvær opptil 600-700 moh med mye vind fra sørvest og noe nedbør og snøtransport mot østvendte sider. Vindutsatte formasjoner er avblåst eller har gammel skare.

I høyden over ca. 800 moh finnes det aktive vedvarende svake lag av kantkorn under skarelag. Laget ble dannet i kuldeperioden i januar.

Onsdag morgen har det gått et svært stort skred i Tamokdalen.

20 cm nysnø i Tamokdalen siden i går.

Advice

The bulletin is a planning tool and may differ from the actual situation. Always make your own evaluation. To be 100 % avalanche safe, avoid all avalanche terrain.

Avalanche risk assessment

NB: oppdatert 07.04.21: Mer nedbør enn ventet og store naturlig utløste skred observert. Nysnø og kraftig vind gir stor pålagring av fokksnø i leheng, og fare for svært store naturlig utløste skred på svakt lag av kantkorn og nedføyket svakt lag med nysnø.
Skredfaren ventes å avta gradvis utover dagen når været roer seg.
