Avalanche warning for region Nord-Troms Tuesday 17.03.2020

Danger level 3 - Considerable avalanche danger

Published:
Avoid lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger there.

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).

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 16. March 2020

Nedbør som snø og kraftig vind fra vestlig og nordvestlig retning, har ført til stor snøtransport og fokksnødannelse mange steder i fjellet. Tidlig i forrige uke var det mildvær opp til ca. 600 moh, og etter dette har det dannet seg et skarelag høyt i snødekket under mildværsgrensa.

Det finnes et vedvarende svakt lag av kantkorn under skarelag fra januar. Det er trolig mest fremtredende i indre deler av regionen, men ligger stort sett dypt i snødekket og er vanskelig å påvirke.

Mountain weather

Monday 16. March 2020

8-12 mm precipitation. Fresh breeze from southwest, changing to strong gale from the northwest during the afternoon. -13 °C to -8 °C at 1100 m a.s.l. Cloudy.

Tuesday 17. March 2020

2 mm precipitation, up to 8 mm in the most exposed areas. Moderate gale from west, changing to fresh breeze from the southeast during renoon. -12 °C to -8 °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

I leområder hvor det er lastet inn mye snø de siste dagene, vil det fremdeles være lett å løse ut skred. Der det har kommet mest snø kan skredene bli store.

Med roligere vær vil fokksnøflakene gradvis stabiliseres og skredfaren er synkende siste halvdel av dagen.
