Avalanche warning for region Jotunheimen Monday 06.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with fresh windloaded snow. Avoid lee areas where a persistent weak layer can be hidden in the snow pack. Avalanches are triggered most easily where the snow pack is thin, typically close to ridges and on convex formations.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.

Below you can see a description of the current snow cover information and current weather forecast in the mountains. If your observations deviate greatly from what is described here, the warning will not necessarily apply either. Always make your own judgments or stay away from avalanche terrain.

Snow cover (in Norwegian)

Sunday 5. January 2020

Vind og snø den siste tiden har lagt opp en del fokksnø i østvendte heng. I andre himmelretninger består snøverflaten av avblåst skare opp til ca. 1000 moh etter mildvær tidligere i uka, og vindpåvirket snø over denne høyden.

Det finnes kantkorn ved bakken og kantkorn under skarelaget som ble dannet av mildværet i slutten av desember. Det finnes også lokalt nedsnødd overflaterim. Det varierer hvor lett det er å utløse skred i disse lagene. Utbredelsen av rimet er begrenset.

Lørdag ettermiddag ble det observert enkelte skred i brattheng og noen skavelbrudd i Vang. I tillegg ble det observert noen sprekkdannelser i fokksnøen.

Mountain weather

Sunday 5. January 2020

10 mm precipitation, up to 35 mm in the most exposed areas. Strong breeze from southwest, changing to gale from the west during the afternoon. -11 °C to -2 °C at 1800 m a.s.l. Cloudy.

Monday 6. January 2020

4 mm precipitation, up to 10 mm in the most exposed areas. Fresh breeze from southwest, changing to moderate gale from the southwest during renoon. -5 °C to 1 °C at 1800 m a.s.l. 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

Vind og nedbør vil gi noen ferske fokksnøflak i høyden og fokksnøflakene fra søndag kan også fortsatt være ustabile. Stedvis kan det være mulig å påvirke kantkorn under skarelag og ved bakken. I de lavestliggende områdene av regionen kan mildværet gi noen mindre våte løssnøskred.
