Avalanche warning for region Jotunheimen Wednesday 04.12.2019

Danger level 3 - Considerable avalanche danger

Published:
Conditions are challenging. A persistent buried weak layer can cause large avalanches. Remote triggering is possible.

Avalanche problems

Persistent weak layer (slab avalanches)

You can very easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2). Remote triggering is possible.

Buried weak layer of faceted snow near surface

Snow cover (in Norwegian)

Wednesday 4. December 2019

Vind og nedbør siste døgn preger snøoverflata, det har vært mildvær og regn nesten opp til fjelltopphøyde. Nedover i snøpakka ligger det gamle fokksnøflak.

Tynt snødekke og kaldt vær i november har gitt kantkorndanning ved bakken og noen steder kantkorn også høyere i snødekket.

I forrige uke ble det observert drønn og skytende sprekker i Skjåk, Dette tyder på at vedvarende svake lag er aktive og lett å påvirke. Det er usikkert hvor mye de siste dagers mildvær har påvirket snøen nedover i snøpakka.

Mountain weather

Tuesday 3. December 2019

8 mm precipitation, up to 18 mm in the most exposed areas. Strong breeze from southwest, changing to gale from the west during renoon. -7 °C to 1 °C at 1800 m a.s.l. Cloudy.

Wednesday 4. December 2019

5 mm precipitation, up to 10 mm in the most exposed areas. Gale from southwest. -6 °C to -1 °C at 1800 m a.s.l. Partly cloudy.

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

Litt ny nedbør, sterk kuling og fortsatt mildt vær ventes å gi moderat pålagring ettersom mildvær og vind allerede har påvirket snødekket. Det ventes fortsatt at det vil være lett å løse ut skred i kantkornlagene. De fleste skredene forventes imidlertid å være små og middels store. Fjernutløsning er mulig!
