Avalanche warning for region Tromsø Thursday 07.05.2020

Danger level 3 - Considerable avalanche danger

Published:
Wind and precipitation from northwest increases the avalanche danger. Locally large amounts of snow are expected. Avoid areas with wind deposited snow, typically behind ridges, ribs and in gullies. Both wet and dry avalanches can trigger naturally. Be aware of cornices.

Avalanche problems

Wind drifted snow (slab 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

Wet snow (loose snow avalanches)

on some 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)

Wednesday 6. May 2020

I skogen er snødekket vått fra topp til bunn og det begynner å bli "råtten" snø. I skoggrensa er det forsatt vått men bærende og snøen er fuktig til rett over skoggrensen. Fra ca 600moh er det full vinter med fokksnø. Det er mer snø enn normalt i regionen, og det finnes flere store skavler.


Det er tidligere i sesongen observert et vedvarende svakt lag av kantkorn dypt i snødekket over 800 moh. Laget er trolig svært vanskelig å påvirke.

Mountain weather

Wednesday 6. May 2020

10 mm precipitation, up to 20 mm in the most exposed areas. Strong breeze from southwest, changing to fresh breeze from the west during the afternoon. -3 °C to 0 °C at 700 m a.s.l. Cloudy.

Thursday 7. May 2020

25 mm precipitation, up to 45 mm in the most exposed areas. Moderate gale from west, changing to fresh breeze from the northwest during the evening. -5 °C to 0 °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

Det blir kaldere og det ventes snø nesten til fjæra. Bygevær fra nordvest gir lokale forskjeller og det kan komme betydelige mengder der snør mest. Dette gir ytterligere påfyll av snø i leheng mot øst og sørøst. Skred kan løsne av seg selv og bli store.

Vær forsiktig rundt skavler.
