Avalanche warning for region Jotunheimen Saturday 28.04.2018

Danger level 2 - Moderate avalanche danger

Published:
Predominantly stable conditions, but be aware in steep lee areas in higher elevations, small dry wind slabs are possible to release. Be careful close to and in terrain traps. If/when the sun comes out, the danger will rise to 2-moderate also in areas where the snow becomes wet and soft.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

Wet snow (loose snow avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Loose snow

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)

Friday 27. April 2018

Det ligger flere dager gamle fokksnøflak i leområder i de fleste himmelretnigner. Denne fokksnøen ligger stedvis på løsere lag av nysnø eller sprøhagl. Tidligere har høye temperaturer påvirket snøen høyt til fjells, og under 1400 moh er snødekket vått og uten lagdelinger. Frost de siste nettene har stabilisert det gamle snødekket.

Høyt til fjells i nordlig sektor kan det fortsatt finnes vedvarende svakte lag dypt i snødekket.

Det har blitt observert små løssnøskred flere steder i regionen de siste dagene.
Torsdag ble ett lite tørt flakskred løst ut av skiløper i S-vendt heng 2000 moh i Lom. Det gikk på nedføyket svakt lag med nysnø.

Mountain weather

Friday 27. April 2018

Little to no precipitation. Breeze from west. -7 °C to -2 °C at 1800 m a.s.l. Partly cloudy.

Saturday 28. April 2018

Little to no precipitation. Breeze from west. -9 °C to -3 °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

Skredfaren er gradvis synkende, men over 1600 m tar det lenger tid før fokksnøflakene som har blitt dannet de siste dagene stabiliserer seg. Under 1400 m vil skredproblemet være begrenset til våte løssnøskred i solvendte sider sent om ettermiddagen.
