Avalanche warning for region Jotunheimen Monday 10.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Complex situation with persistant weak layers. Avalanches are triggered most easily where the snow pack is thin, typically close to ridges and on convex formations. Remote triggering from less steep terrain is possible.

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 some 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 9. February 2020

Snøoverflaten består av fokksnø med ulik hardhet fra siste snøfall og kraftige vind. Dypere i snødekket finnes eldre fokksnøflak og skarelag. Det er ujevn snøfordeling med mest i Ø-N. Rygger og kuler i terrenget er stedvis avblåst.

Eldre vedvarende svake lag ligger under bærende snø og anses ikke som et skredproblem for tiden. Et kantkornlag over skarelag finnes høyere i snødekket, men utbredelsen av det er noe usikker.

Et str 3 skred naturlig utløst i SØ på Breikvamsnosi gikk trolig natt til torsdag. Lørdag er det observert et str 4 skred nordøst for Lom i en østside på ca 1050 moh.

Mountain weather

Sunday 9. February 2020

30 mm precipitation, up to 50 mm in the most exposed areas. Gale from south, changing to storm from the south during the afternoon. -10 °C to -4 °C at 1800 m a.s.l. Cloudy.

Monday 10. February 2020

10 mm precipitation, up to 18 mm in the most exposed areas. Strong breeze from south, changing to moderate gale from the west during renoon. -11 °C to -4 °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

Skredfaren vil opprettholdes så lenge nedbør og vind står på. Den ferske fokksnøen øker belastningen på svake lag i snødekket og gjør at det vil være lettere å løse store skred i kantkornlaget. Enkelte naturlig utløste skred kan fortsatt forekomme. Fjernutløsning er mulig.
