Snow Cover

93 cm in total Some snow drift 0 cm new snow Snow line at 0 masl Storm slab (soft slab) Dry Snødekket fra siste snøfall er i hovedsak borte etter en del regn og vind. Litt kaldere temperaturer nå. Gjennomsnittlig 10 cm nysnø i lavlandet/skogen, og i snitt 30cm snø over skoggrensa. Mye forblåst terreng på fjellet og gjennomslagsskare. Men opphoping av noe snø i lesider.

Avalanche Danger Assessment

1 Low Temperaturene er fortsatt relativt stabil, og snødekket er fuktig i bunnen. Fant ikke utvikling av kantkorn. Med lavere temperaturer så kan det forventes en omvandling til kantkorn i snødekket. Forecast too high
