Avalanche warning for region Hallingdal Tuesday 28.03.2023

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

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).

Snow cover (in Norwegian)

Monday 27. March 2023

Søndag morgen ligger det ca 10-15 cm tørr nysnø i terrenget på hardt underlag. Det har vært generelt lite vind de siste dagen så den siste snøen er stort sett løs, men det kan ligge noen myke fokksnøflak der vinden har tatt mest, særlig i leområder vendt mot sør og vest.

Flere runder med mildvær de siste ukene har ført til flere skarelag i snødekket. Sola har påvirket snødekket til topps i solvendte sider.

Det finnes flere kantkornlag i snødekket. Kantkornlagene er stort sett dekket av harde skarelag og vanskelig å påvirke, men fredag ble det registrert et drønn i snødekket ved Liastølene i Mørkedalen. Dette viser at det ikke helt kan utelukkes som problem.

Det har gått noen små løssnøskred i nysnøen på søndag.

Mountain weather

Tuesday 28. March 2023

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

Der vinden blir sterk nok til å flytte snø inn i leområder kan det være lett å løse ut skred i ferske fokksnøflak.

Vedvarende svake lag ligger under harde skarelag og er stort sett vanskelig å påvirke.
