Avalanche warning for region Nord-Trøndelag Tuesday 08.03.2022

Danger level 3 - Considerable avalanche danger

Published:
There are unstable windslabs at higher elevations. Avoid areas where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger here.

Avalanche problems

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).

Buried weak layer of new snow

Wet snow (slab avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4).

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.

Mountain weather

25 mm precipitation, up to 70 mm in the most exposed areas. Rain up to 800 m a.s.l during the afternoon. Strong breeze from west. -4 °C to 0 °C at 1100 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

De siste dagene har vært preget av store nedbørsmengder og milde temperatur. Over mildværsgrensa vil det ha bygget seg opp store, ustabile fokksnøflak i leheng. Disse vil det være lett for en skiløper å løse ut, særlig der flakene er myke og/eller tynne.

Det er fortsatt usikkerhet rundt hvordan gamle svake lag tåler økt belastning og svekkelse i form av regnvær. Det kan tar tid før vannet trenger ned i snødekket og svekker det nok til at skredene løsner.

Varselet er basert på et enklere datagrunnlag enn regionale varsler og utgis kun i forbindelse med faregrad 4 og 5.
