Avalanche warning for region Indre Troms Wednesday 04.03.2020

Danger level 3 - Considerable avalanche danger

Published:
The danger increases when the wind picks up. Avoid areas with wind deposited snow, typically behind ridges, ribs and in gullies.

Avalanche problems

Wind drifted snow (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).

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).

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)

Tuesday 3. March 2020

Det er mye snø i terrenget. Over skoggrensa varierer det mellom løs snø, lett vindpåvirket og hard fokksnø på de mest utsatte stedene.

Det finnes et vedvarende svakt lag av kantkorn under skarelag fra 20/1. Det er kun funnet mellom 400-800 moh, og er generelt vanskelig å påvirke.

Skiløperutløst skred str1 rett over skoggrensa på Vesleala nord for setermoen søndag.

Det meldes om god stabilitet i fokksnøen lørdag og søndag.

Mountain weather

Tuesday 3. March 2020

Little to no precipitation. Breeze from northwest. -18 °C to -9 °C at 1100 m a.s.l. Partly cloudy.

Wednesday 4. March 2020

No precipitation. Fresh breeze from southeast, changing to moderate gale from the southeast during the afternoon. -18 °C to -11 °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

Den gamle fokksnøen virker å ha god stabilitet men Vinddreining og vindøkning vil gi ustabile fokksnøflak i nye leformasjoner. Det er mye løs snø i terrenget som vinden kan flytte på og skredfaren vil øke i takt med vinden onsdag.

Kantkornlag finnes i store deler av regionen, men virker de fleste steder å være svært vanskelig å påvirke. Utvis varsomhet i overganger mellom tynt og tykt snødekke.
