Avalanche warning for region Jotunheimen Monday 30.12.2019

Danger level 3 - Considerable avalanche danger

Published:
Locally unstable conditions due to wind slabs in lee areas. Persistent weak layers may also be triggered where the snow cover is thin.

Avalanche problems

New snow (slab avalanches)

You can easily trigger avalanches on many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

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.

Snømengden varierer med terrenget, med lite snø i vindutsatte områder og mer snø i leområder.

Observasjon fra Bøverdalen lørdag viser vedvarende svake lag av begerkrystaller ved bakken og nedsnødd kantkorn/rim høyere i snødekket.

Overflaterim er registrert flere steder de siste dagene. Ligger på overflate med varierende hardhet.
Søndag kl 12 ble det målt kortvarig plussgrader på Juvasshøe (1894moh). Nedbør og SV storm.

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

I noen lesider vil det være lett å løse ut store skred i et lag med begerkrystaller ved bakken, særlig i midtre deler av regionen. Over mildværsgrensen er det fersk fokksnø som er lett å løse ut i lesider. Økende omfang med høyde, og mest vest i regonen. Fokksnø vil sannsynligvis feste seg godt til underlaget i takt med at det fryser til.
