Another day of whiteout conditions, continual snow showers and accurate navigation. This made observations difficult, but there is plenty of windslab on South-West through to North-West aspects. This will start to be redeposited tomorrow as the wind veers to the South-West overnight.
The trend of cold weather looks set to continue and new windslab will build, containing instabilities on North-West through to East aspects tomorrow.

 

This block of windslab slid out easily demonstrating a weakness due to dry soft snow under firm slab.

 

Two skiers in the whiteout. This makes the visibility look ok. Don’t be fooled it was universally awful.

 

Cracks in windslab at ~1000m on a WSW aspect. Indicative of instabilities in the snowpack.
