Avalanche warning for region Jotunheimen Thursday 21.03.2019

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with wind deposited snow at high elevations. Increasing temperature will weaken the snow cover temporarily.

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 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)

Wednesday 20. March 2019

Sist helg kom det mykje snø i kombinasjon med vind frå aust. Denne snøen ligg no som fokksnø av ulik hardheit i leområder. I forsenkningar og skjerma områder over mildværsgrensa ligg det lausare og mjukare snø.

Før siste snøfall kom det fleire observasjonar på svake lag nede i det eldre snødekket. Det finnes nedføyka kantkorn og rim, samt kantkorn over skarelag. Alle desse kan utgjøre svakt lag som skred kan løsne på.

Mandag var det observert fleire naturleg utløyste skred i regionen.

Mountain weather

Wednesday 20. March 2019

8 mm precipitation, up to 17 mm in the most exposed areas. Gale from west, changing to moderate gale from the southwest during the evening. -9 °C to -4 °C at 1800 m a.s.l. Partly cloudy.

Thursday 21. March 2019

10 mm precipitation, up to 20 mm in the most exposed areas. Gale from west, changing to fresh breeze from the west during the evening. -10 °C to 0 °C at 1800 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

Nysnø og kraftig vind vil legge opp store mengder fersk fokksnø i leområder over mildværsgrensa. Mildvær og regn i låglandet kan kortvarig svekke snødekket, men varmen vil også gi forholdsvis rask stabilisering. Svake lag i det eldre snødekket kan bli påvirka både av mildværet og av den auka fokksnømengda, og skred kan bli store.
