Melt, freeze, then fresh snow
13th December 2021
Warm conditions last night when the temperature at 1200 metres rose to 4 degrees C were followed by colder conditions today. This has helped to further consolidate the existing snowpack. Localised areas of fresh, moderately bonded, windslab were deposited today mainly on North to East aspects above 900 metres that were sheltered from the strong winds.
The temperatures should be the other way around tomorrow with the colder conditions persisting overnight followed by rising temperatures during the day.
