Avalanche warning for region Indre Troms Wednesday 23.03.2022

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. In the lower areas wet loose snow avalanches can occur.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously 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 new snow

Wet snow (loose snow avalanches)

You can easily trigger avalanches on a few 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)

Tuesday 22. March 2022

Snøoverflaten er smelteomvandlet opptil ca. 1000 moh etter kraftig regnvær på lørdag og mildvær søndag.

Ovenfor dette høyde er overflate enten avblåst eller vindpakket.

Det finnes flere svake lag med kantkorn inn i det gamle smelteomvandlet snødekke. Ved bakken finnes det begerkrystaller. Disse lag har i det siste vært vanskelig å påvirke. Det er usikkerhet rundt status av disse lagene etter regnvær på lørdag.

Observasjoner fra helikopterbefaring over Indre Troms viser det har gått mange middels og store skred i østlige heng under været lørdag kveld og natt til søndag.

Mountain weather

Tuesday 22. March 2022

8 mm precipitation, up to 20 mm in the most exposed areas. Rain up to 700 m a.s.l during the afternoon. Breeze from west, changing to strong breeze from the southwest during the afternoon. -5 °C to -1 °C at 1100 m a.s.l. Cloudy.

Wednesday 23. March 2022

15 mm precipitation, up to 32 mm in the most exposed areas. Rain up to 800 m a.s.l during renoon. Moderate gale from west, changing to fresh breeze from the north during the evening. -7 °C to 0 °C at 1100 m a.s.l. 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

Onsdag fortsetter med mye nedbør og skredfaren øker. Over mildværsgrensa vil fokksnøflakene nå få så stor belastning at de i enkelte heng kan løse ut naturlig. Skred kan bli store. Om kvelden dreier vinden nordlig og man kan få ustabile fokksnøflak i flere heng.

Under mildværsgrensa vil det kunne gå våte løssnøskred.
