Avalanche warning for region Indre Troms Monday 18.04.2022

Danger level 3 - Considerable avalanche danger

Published:
The stability of the snowpack is poorer due to rising temperatures. Wet avalanches can release naturally. Avalanches on persistent weak layers can get very big. Avoid therefore avalanche terrain. Some fresh wind slabs can be easy to trigger at the highest peaks.

Avalanche problems

Wet snow (slab avalanches)

Avalanches may release spontaneously on some 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

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose snow

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)

Sunday 17. April 2022

Snøoverflata er påverka av mildvêr. Under mildvêrsgrensa, er snøen truleg vere fuktig eller våt. Over mildvêrsgrensa varierar det mellom vindpåverka snø av ulik hardheit og ubunden snø i skjerma områder.

Over mildvêrskara fra mars ligg det eit svakt lag av kantkorn. Det svake laget er dekt av fokksnøflak av ulik hardhet og har ført til fleire skred den siste tida.

Søndag var det observert eit flakskred på Trondfjellet.

Mountain weather

Sunday 17. April 2022

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

Det er eit ugunstig oppbygd snødekke med eit vedvarande svakt lag i samband med skare. Det er fare for store til svært store naturleg utløyste skred sidan stabiliteten til laget kan ha blitt svekka av stigande temperaturar dei siste dagane.

Det kan også gå våte laussnøskred i bratte heng. Unngå difor skredterreng.
