Avalanche warning for region Jotunheimen Sunday 25.04.2021

Danger level 2 - Moderate avalanche danger

Published:
There is a persistent weak layer buried in the snow pack. Be careful in areas with wind deposited snow.

Avalanche problems

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow above a crust

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).

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)

Saturday 24. April 2021

På snøoverflata ligg det mange stader litt turr laussnø.
Under denne finn me for det mest hard og berande fokksnø. Der sola har varma snødekket, og opp til mildversgrensa er det skare i overflata.

Det finst vedvarande svakt lag av kantkorn mellom skarelag og fokksnø flere stader i varslingsregionen. Dette er observert ved Tyin og i Leirdalen, der både drønn og skredaktivitet kan koblast til dette svake laget.
Det finst også vedvarande svake lag djupt i snødekket.

Det har vore sterk vind med snøfokk frå NV denne veka.

Mountain weather

Saturday 24. April 2021

Little to no precipitation. Breeze from north. -14 °C to -7 °C at 1800 m a.s.l. Partly cloudy.

Sunday 25. April 2021

No precipitation. Breeze from north. -18 °C to -7 °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

I delar av regionen, mest i NV finst det fokksnøflak som vart danna tidlegare i veka. Desse stabilserar seg gradvis.

Vedvarande svake lag i det gamle snødekket kan framleis vere mogeleg å påverke der snødekket er tynt, men stort sett er dei svake laga dekka av berende snø og gjev få eller ingen fareteikn.
