Avalanche warning for region Tromsø Sunday 21.05.2023

Danger level 2 - Moderate avalanche danger

Published:
Wet natural avalanches possible in highet altitudes. The avalanche increase with sun and warmer temperatures in the mountain. Be careful in avalanche release and run out areas.

Avalanche problems

Wet snow (slab avalanches)

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

Water pooling in/above snow layers

Wet snow (loose snow avalanches)

Avalanches may release spontaneously 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)

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)

Saturday 20. May 2023

Det er fortsatt en god del snø i fjellet, men generelt lite snø under 300 - 400 moh, særlig i sørvendte sider. Høyt til fjells kom det noe nysnø 17. mai. Det gamle snødekket er for det meste smelteomdannet.

Natt til lørdag var det plussgrader om natten helt til fjelltopphøyde. Da var det 8 grader ved værvarslinga i Tromsø (800moh). I naboregionen Lyngen var ble det målt 1 grad på rundt 1000 moh flere steder.

Mountain weather

Saturday 20. May 2023

6-10 mm precipitation. Precipitation as rain. Moderate gale from southwest. 2 °C to 7 °C at 700 m a.s.l. Cloudy.

Sunday 21. May 2023

5-8 mm precipitation. Precipitation as rain. Strong breeze from southwest, changing to fresh breeze from the southwest during the afternoon. 3 °C to 11 °C at 700 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

Stigende temperaturer vil føre til snøsmelting og vått snødekke. Enkelte våte løssnøskred kan løsne naturlig i svært bratt terreng.

Det har nå vært et par netter uten nattefrost, også i høyden. I fjellet kan det derfor løsne et og annet vått flakskred pga. vann som samler seg opp ved bakken eller over gamle skarelag.

Sannsynligheten for glideskred og skavelbrudd øker noe når det er varmt, men det er vanskelig å forutsi når dette skjer. Unngå langvarig opphold under sigesprekker, og hold god avstand til skavler.
