Avalanche warning for region Nord-Troms Monday 20.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Avoid lee areas with wind deposited snow in the alpine, typically behind ridges, ribs and in gullies. Naturally triggered wet avalanches are expected below 300 masl steep terrain.

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)

You can easily trigger avalanches on some 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)

Sunday 19. January 2020

Etter mange dager med relativt lite vind er det fortsatt løs snø i terrenget. Snøen er noe mer vindpåvirket over tregrensa, men også her er det myke flak og løs snø mange steder. Der vinden har fått tak ligger hardere fokksnø og på svært vindutsatte steder er det avblåst. Lavtrykket som kommer inn mandag vil endre på snødekket.

Det er tidligere observert lag med kantkorn over/under skarelag over ca 600 moh, men det er ikke registrert aktivitet fra dette laget den siste tiden.

Mountain weather

Sunday 19. January 2020

1-3 mm precipitation. Strong breeze from southeast, changing to strong breeze from the south during renoon. -14 °C to -6 °C at 1100 m a.s.l. Partly cloudy.

Monday 20. January 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 the evening. -8 °C to -1 °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

Det kommer nytt lavtrykk med nedbør og temperaturstigning. Skredfaren øker i det været slår inn. Der nedbøren kommer som snø vil det legges opp ferske fokksnøflak. Der pålagringen er størst vil det være lett å løse ut skred og skred kan bli store. Der nedbøren kommer som regn kan våte skred løsne av seg selv.
