Avalanche warning for region Sør-Troms Monday 09.03.2020

Danger level 3 - Considerable avalanche danger

Published:
Strong wind from a more Southernly direction can form new unstable wind slabs in the alpine. Areas not affected by the wind will quickly form strong bonds due to favourable conditions. At lower elevations naturally released wet avalanches are likely.

Avalanche problems

Wet snow (slab avalanches)

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

Water pooling in/above snow layers

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

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)

Sunday 8. March 2020

Nedbøren fredag og lørdag ventes å ha lagt igjen 10-20 cm nysnø.

I høyden er snødekket fra tidligere preget av fokksnø av varierende hardhet. Vindutsatte formasjoner er stedvis avblåst til gammel mildværskare.

Det finnes løs snø tilgjengelig i skjermede områder. I skogen ligger det til dels mye ubundet snø.

Gammelt snødekke består i stor grad av ulike skarelag og smelteomvandlet snø.

Lørdag er det observert et naturlig utløst flakskred i et bratt leheng mellom Sørreisa og Salangen.

Mountain weather

Sunday 8. March 2020

Little to no precipitation. Breeze from southeast, changing to strong breeze from the southeast during the afternoon. -9 °C to -2 °C at 700 m a.s.l. Partly cloudy.

Monday 9. March 2020

11 mm precipitation, up to 22 mm in the most exposed areas. Strong breeze from south, changing to moderate gale from the southwest during the afternoon. -6 °C to 2 °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

Vinden dreier til en mer sørlig retning, og en mildere værtype er ventet. Kraftig vind vil fortsette å gi pålagring i leområder, men nå i nye himmelretninger. Det kan trolig være lette å løse ut store skred i disse områdene. Områder som ikke blir påvirket av vinden har gunstige betingelser for stabilisering pga. milde temperaturer.
I lavlandet ventes det våte naturlig utløste skred.
