Avalanche Summary

There are no new recent reports of avalanche activity.

Snowpack Summary

A 2-3cm rain crust is now buried by 5-10cm of new snow in the alpine and at tree line. This all overlies well settled storm snow from last week's series of storms that seems to have a good bond to the layers below. An old rain crust is reported to be down 150-180cm in the North Shore mountains. This layer has strengthened in snowpack tests and is unlikely to trigger in most places now.

Avalanche Problems

Wind Slabs

Additional new snow combined with moderate winds have created new wind slabs in the lee of terrain features

Be cautious as you transition into wind affected terrain.

Aspects: North, North East, East, South East.
