In many areas, the snowpack is melt‑transformed, coarse‑grained, and drains water well. However, wet avalanches may still release naturally in exposed terrain, especially if the mild temperatures become more pronounced than expected. Wet loose avalanches are the most likely problem. Most are expected to be small, but medium‑sized avalanches may occur.

At higher elevations, layering in the snowpack is still present. If mild temperatures reach these elevations, meltwater can penetrate downward and weaken the layers, potentially producing wet slab avalanches. These avalanches are difficult to forecast and can be larger than typical loose‑snow avalanches. Glide avalanches may also occur where water accumulates above smooth bed surfaces such as rock slabs.

Mange steder er snødekket smelteomvandlet, grovkornet og drenerer vann godt. Likevel kan våte skred fortsatt løsne naturlig på utsatte steder, særlig dersom mildværet blir mer omfattende enn ventet. Våte løssnøskred er det mest sannsynlige skredproblemet. De fleste ventes å være små, men middels store skred kan forekomme.

Høyt til fjells finnes det fortsatt lagdeling i snødekket. Hvis mildværet når opp i disse høydene, kan smeltevann trenge ned i snødekket og svekke lagene, noe som kan gi våte flakskred. Slike skred er vanskelige å varsle og kan bli større enn typiske løssnøskred. I tillegg kan glideskred forekomme der vann samler seg over glatte underlag som svaberg.

Snøoverflaten har et tydelig vårlig preg, og det har vært kraftig smelting den siste tiden. Sammenhengende snø finnes fra omtrent 300–500 moh og oppover, avhengig av hvor i regionen du befinner deg, med mest snø i nordvendt terreng og i indre strøk. Snødekket er i hovedsak smelteomvandlet. Likevel kan det fortsatt finnes noe lagdeling igjen i skyggesider og på de høyeste toppene.

An overcast night followed by a sunny afternoon with high temperatures will increase the water content in the snowpack. In many areas, the snowpack is melt‑transformed, coarse‑grained, and drains water well. However, wet avalanches may still release naturally in exposed terrain, especially on steep, sun‑exposed slopes. Wet loose avalanches are the most likely avalanche problem. Most are expected to be small, but medium‑sized avalanches may occur.

At higher elevations, layering in the snowpack is still present, particularly in northern aspects. With strong meltwater production, water can percolate downward and weaken these layers, potentially triggering wet slab avalanches. These avalanches are difficult to forecast and can be larger than typical loose‑snow avalanches. Glide avalanches may also occur where water accumulates above smooth bed surfaces such as rock slabs. In addition, cornices may weaken and break as temperatures rise.
