Avalanche warning for region Helgeland Thursday 21.03.2024

Danger level 2 - Moderate avalanche danger

Published:
The snow pack is gaining strength after a few days of warm weather. There is still some uncertainty regarding persistent weak layers. Safe travel conditions on many slopes.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

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)

Wednesday 20. March 2024

Det har kommet ca. 15 - 25 cm med nysnø siden sist torsdag. Dette har blitt preget av mildvær i lavlandet og sterk vind fra ulike retninger på snaufjell.

Før siste snøvær ble det observert kantkorn og rim i overflaten. Det er foreløpig usikkert om disse svake lagene ble ødelagt av vinden før de ble nedsnødd, eller om de nå ligger under nysnøen. Det finnes lag av kantkorn også lenger ned i snøen, men de er stort sett skjermet av hard fokksnø/skare.

Mountain weather

Wednesday 20. March 2024

4 mm precipitation, up to 10 mm in the most exposed areas. Rain up to 700 m a.s.l Wednesday night. Fresh breeze from southwest. -6 °C to -1 °C at 1100 m a.s.l. Cloudy.

Thursday 21. March 2024

2-5 mm precipitation. Rain up to 400 m a.s.l Thursday night. Breeze from southwest, changing to strong breeze from the southeast during the evening. -6 °C to -2 °C at 1100 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

Snødekket er i ferd med å stabilisere seg etter mildværet. Fokksnøen har stabilisert seg godt og regnes ikke som et problem lengre.

Det er fortsatt noe usikkerhet rundt svake lag i skoggrensen, men også her ser det ut til at laget stabiliserer seg.

Vinddreining på kvelden kan gi fokksnøproblem i nye områder mot vest, men trolig først i løpet av fredagen.
