Avalanche warning for region Trollheimen Wednesday 01.04.2020

Danger level 3 - Considerable avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies in the alpine. Wet avalanches are expected under 1000 masl.

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).

Poor bonding between layers in wind deposited snow

Wet snow (loose snow avalanches)

on a few 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)

Tuesday 31. March 2020

Det har kommet mye snø de siste dagene og enkelte områder har fått over 50 cm. Kraftig vind fra NV har flyttet mye snø inn i heng skjerma for vinden. Det eldre snødekket er preget av mildvær høyt til fjells i forrige uke og stedvis skare. I lavlandet er snøen generelt smelteomdanna og stabil.

Det er mye snø i fjellet og store skavler mot Ø.

Observasjoner mandag forteller om at nysnøen i Storlidalen er mindre vindpåvirka enn lengre vest i regionen. Det er minst nysnø øst i regionen ved Oppdal

Mountain weather

Tuesday 31. March 2020

10 mm precipitation, up to 20 mm in the most exposed areas. Strong breeze from southwest, changing to moderate gale from the west during renoon. -9 °C to -2 °C at 1400 m a.s.l. Cloudy.

Wednesday 1. April 2020

10 mm precipitation, up to 18 mm in the most exposed areas. Fresh breeze from northwest, changing to moderate gale from the west during the evening. -7 °C to -1 °C at 1400 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

Når vinden tar seg opp utover dagen vil det på ny dannes fokksnøflak i le for vinden, hovedsakelig mot Ø. Fokksnøen er mest ustabil mens været står på, men generelt er det krevende å ferdes i fjellet for tiden. Stigende temperatur svekker også snødekket og faren for våte naturlig utløste skred under mildværsgrensa øker når det regner som mest. Husk også at det er store ustabile skavler og at glideskred som løsner på glatt underlag er vanskelig å forutse, hold derfor avstand til glidesprekker.
