The storm continues, bringing periods of new snow combined with strong winds in the mountains. Above the freezing level, unstable wind slabs are forming and may release naturally or be very easy to trigger while snow showers are ongoing. Between showers, these slabs are expected to stabilize relatively quickly due to mild temperatures. The largest amounts of precipitation are expected in the southwestern part of the region.

Persistent weak layers now lie deep beneath the windslabs and are not considered a widespread avalanche problem. Large avalanches are considered unlikely, but cannot be completely ruled out in isolated areas. Westerly winds have built large cornices, which may become particularly weak under mild temperatures at higher elevations.

In the lowlands, the snow is already saturated and is expected to handle the rain well. However, slightly higher in the terrain, where the snowpack is still layered wet avalanches may still release naturally.

Været står fortsatt på og gir perioder med nysnø kombinert med kraftig vind i fjellet. Over mildværsgrensen dannes ustabile fokksnøflak som kan løsne av seg selv eller være svært lette å løse ut mens bygene pågår. Mellom bygene ventes flakene å stabilisere seg relativt raskt på grunn av milde temperaturer. Største nedbørsmengden ventes i sørvestlig del av regionen.

Vedvarende svake lag ligger nå dypt under fokksnøen og vurderes ikke som et utbredt skredproblem. Store skred anses som lite sannsynlig, men kan ikke helt utelukkes enkelte steder. Vestavinden har bygd opp store skavler, som kan bli særlig svake under milde temperaturer i høyden.

I lavlandet er snøen smelteomvandlet og grovkornet, noe som gir lavere skredfare. Men litt høyere i terrenget hvor snødekket fremdeles er lagdelt og det finnes litt nysnø på overflaten er det mulig at våte skred løsne naturlig.

Snødekket er tydelig preget av mildværet siste tiden. Opp til rundt 1000 moh er snøoverflaten noen steder fuktig etter regnværet onsdag - primært sør i regionen. Over ca. 700 moh blir snøen gradvis tørrere og mer vindpåvirket jo høyere man kommer. Før uværet traff regionen fantes kantkorn over 500 moh., både høyt i snødekket og dypere rundt skarelagene fra 18. januar og 8. februar. Det ble observert bruddforplantning i disse lagene, særlig fra 800 moh og oppover. Status for disse lagene etter all nedbør og de milde temperaturene er usikker, ettersom det ikke har kommet inn observasjoner fra relevant høyde de siste dagene.

Avalanche danger is determined by the amount of new snow and wind. The largest precipitation amounts are expected in the southern part of the region. Here, strong winds can transport snow into lee slopes and form unstable wind‑slabs that may release naturally or be very easy to trigger while snow showers are ongoing. These slabs are expected to stabilize relatively quickly due to mild temperatures, but should be considered unstable when freshly formed. Further north in the region, where less new snow is expected, the avalanche danger will be moderate (FG2).

Persistent weak layers at high elevations now lie deep beneath the wind‑drifted snow and are not considered a widespread avalanche problem. Large avalanches are unlikely, but cannot be completely ruled out if the snowpack receives a significant additional load, for example from cornice failures.

In the lowlands, avalanche danger is decreasing as temperatures drop.
