Thursday the Hutt Range saw about 10cm of new snow and around 8mm of rainfall. New snow was easy to skier trigger on a smooth rain crust, from Tuesdays storm, especially in steep terrain. Overnight things may setup or freeze quite a bit, but tomorrow looks to be warm with high freezing levels and surface snow may soften midday.
