Avalanche warning for region Svartisen Tuesday 19.12.2023

Danger level 3 - Considerable avalanche danger

Published:
Large naturally released avalanches are likely due to strong winds and heavy precipitation. Avoid avalanche terrain. Remote triggering is possible. At lower elevations, wet avalanches can occur.

Avalanche problems

Persistent weak layer (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.

Buried weak layer of surface hoar

Wet snow (slab avalanches)

Avalanches may release spontaneously 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 19. December 2023

Snødekket er generelt tynt i lavereliggende områder etter mye regn de siste dagene.

I høyere områder kom nedbøren som snø. Mest i indre deler hvor det har kommet 40-70 cm siden lørdag. Det har dannet seg tykke fokksnøflak i leformasjoner grunnet kraftig vind fra hovedsakelig vestlige retninger. Vi antar at svake lag av kantkorn og rim fremdeles er intakte. Det finnes svake lag både ved bakken og høyere opp i snødekket.

Mountain weather

Monday 18. December 2023

35 mm precipitation, up to 65 mm in the most exposed areas. Rain up to 700 m a.s.l during renoon. Moderate gale from west. -4 °C to -1 °C at 1100 m a.s.l. Cloudy.

Tuesday 19. December 2023

20 mm precipitation, up to 50 mm in the most exposed areas. Rain up to 500 m a.s.l Tuesday night. Fresh breeze from southwest, changing to gale from the northwest during the afternoon. -9 °C to -2 °C at 1100 m a.s.l.

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 tirsdag kl 09.

Kraftig vind og lokalt store nedbørmengder gir fare for store naturlig utløste skred. Skredene kan bli store etter flere dager med mye nysnø og kraftig vind.

Under nysnøen er det svake lag av overflaterim/kantkorn som gjør situasjonen krevende. Fjernutløsning er mulig.

Under mildværsgrensen på 500 moh forventes det at snøen nå er gjennomfuktet, og risikoen for naturlig utløste skred avtar. Det er imidlertid fortsatt en mulighet for at enkelte skred kan forekomme.
