Avalanche warning for region Salten Thursday 03.01.2019

Danger level 4 - High avalanche danger

Published:
A short, but intense storm is excepted about midday. Mild temps and heavy rain will quickly weaken the snowpack and naturally released avalanches are expected on many slopes. In the high alpine wind slabs will form rapidly.

Avalanche problems

Wet snow (slab avalanches)

You can very easily trigger avalanches on many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Water pooling in/above snow layers

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of faceted snow near surface

Wind drifted 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)

Wednesday 2. January 2019

De siste dagene er det kommet 40-50 cm nysnø med kraftig vind i fjellet. Nysnøen er ujevnt fordelt i terrenget, men med største snømengder mot NØ-SV. Enkelte steder er den gamle mildværsskare fremme i snøoverflaten.

I lavlandet opptil ca 500 moh er det gamle snødekket fuktig under nysnøen.

Det ble i jula observert kantkorn. Mildværet siste dagene har trolig ødelagt mye av dette laget under ca 500 moh. Over mildværsgrensen er det i naboregionen observert svære drønn i snødekket pga kantkorn og trolig er situasjonen lik i Salten.

Mountain weather

Wednesday 2. January 2019

5 mm precipitation, up to 10 mm in the most exposed areas. Fresh breeze from northwest, changing to breeze from the southwest. -15 °C to -9 °C at 1400 m a.s.l. Cloudy.

Thursday 3. January 2019

35 mm precipitation, up to 55 mm in the most exposed areas. Strong breeze from south, changing to strong breeze from the west during the afternoon. -13 °C to -2 °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

Det neste døgn ventes det et kortvarig, kraftig mildvær. Lokalt kan det komme store nedbørmender som regn på snødekket. Kortvarig vil det være fare for naturlig utløste skred og det oppfordres til å holde seg godt unna skredterreng.

Slår ikke nedbøren til for fullt vil skredfaren være lavere og mer mot 3-betydelig.

Når det verste av nedbøren og vinden har gitt seg vil snødekket trolig stabilisere seg raskt igjen.
