Torsdag og natt til fredag er det kommet ca. 30-40 cm nysnø. Den underliggende snøen i lavlandet er gjennomfuktet av mildværet tidligere i uken. I høyden så har kraftig vind og snøvær ført til en vindpåvirket snøoverflate med store ansamlinger av fersk fokksnø i leheng.
Det er tidligere observert vedvarende svake lag av kantkorn under et skarelag høyt i snødekket over 400 moh, men det er usikkert hvordan mildværet har påvirket dette.
