Avalanche warning for region Tromsø Saturday 15.12.2018

Danger level 1 - Low avalanche danger

Published:
Be careful in areas with fresh wind deposited snow. Keep in mind that even small avalanches can have consequences if you fall into rockery terrain.

Avalanche problems

Wind drifted snow (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Poor bonding between layers in wind deposited 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)

Friday 14. December 2018

De siste dagene har det blåst kuling fra sørvest i fjellet og vært mildvær opp til 600-700 moh. Snøoverflaten har dermed blitt fuktig opp til mildværsgrensa og det har trolig dannet seg fokksnøflak flere steder i høyden.
Det er generelt lite snø i fjellet, med mest snø i renner og forsenkninger og avblåst på rabber og oppstikkende partier.

Det er ikke observert skredaktivitet de siste dagene.

Mountain weather

Friday 14. December 2018

1-3 mm precipitation. Strong breeze from southwest. -3 °C to 2 °C at 700 m a.s.l. Cloudy.

Saturday 15. December 2018

Little to no precipitation. Fresh breeze from southwest, changing to breeze from the south during the afternoon. -4 °C to -1 °C at 700 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

Minkende vind fører til at det vil dannes færre nye, ustabile fokksnøflak i høyden og eldre fokksnøflak vil ha fått stabilisert seg. Lavere temperatur gjør at snøoverflaten gradvis fryser til og stabiliseres ytterligere der det har vært mildvær.
