Avalanche warning for region Trollheimen Monday 24.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Unstable wind slabs may cover a slippery crust in lee areas. Avalaches can be triggered by a single skier. Avoid lee areas where you find wind slabs.

Avalanche problems

Wind drifted 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).

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)

Monday 24. February 2020

Snøoverflata ber preg av mykje hard vind frå vest og sørvest dei siste dagane. Gamalt snødekket er hard og avblese, mens det har lagt seg opp snø i austlege leområder med varierande hardleik.

Det er observert kantkornutvikling under eldre skarelag og i snøoverflata, men det er førebels ikkje eit problem.

Det er observert ein stor temperaturgradient i øvre del av snødekket laurdag.

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

OPPDATERT 24.02.2020 Faregraden oppjustert til FG3 grunna meir nedbør enn forventa.

Kraftig vind frå vest og litt ny nedbør vil gje snøtransport inn i austlege leområder. Her vil ein få auka pålagring og ferske fokksnøflak.
