The avalanche danger is largely controlled by local temperature conditions. A solid overnight freeze can provide a short-term stabilising effect, but once the temperatures rise and sunshine weakens the snowpack the avalanche danger increases.

Wet loose avalanches are the most likely problem. Although most of these avalanches are expected to be small, it is important to remember that even small wet loose avalanches can be dangerous in steep and exposed terrain, as they consist of heavy, dense snow.

At higher elevations, there is still layering in the snowpack, and when meltwater penetrates downward, these layers can weaken and produce wet slab avalanches. Such avalanches are difficult to forecast and can be larger than typical loose‑snow avalanches. In addition, glide avalanches may occur where water accumulates above smooth bed surfaces such as rock slabs.

Skredfaren styres i stor grad av de lokale temperaturforholdene. Der det kommer nattefrost, kan snødekket få en kortvarig stabilisering, og skredfaren vil mange steder kunne oppleves som lav, spesielt tidlig på dagen. Når mildværet og sola får tak svekkes snødekket likevel raskt, og skredfaren øker tilsvarende.

Våte løssnøskred er det mest sannsynlige skredproblemet. Selv om de fleste ventes å være små, er det viktig å huske at også små våte løssnøskred kan være farlige i bratt og eksponert terreng, ettersom de består av tunge og kompakte snømass­er.

Høyt til fjells finnes det fortsatt lagdeling i snødekket. Når smeltevann trenger ned i snødekket, kan disse lagene svekkes og 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 400-600 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.

Rain will further increase the water content in the snowpack, and wet avalanches may still release naturally in exposed areas.

Wet loose avalanches are the most likely avalanche problem. Most of these avalanches are expected to be small, but medium‑sized avalanches may also occur. Remember that even small avalanches can be dangerous in steep and exposed terrain, as they consist of heavy, dense snow.
