No observations. Please provide any snowpack or avalanche observations using the link below.  https://www.avalanche.net.nz/observations The overnight freezing level of 2300m on Saturday will rapidly fall to 1200m on Sunday morning. Snow will fall to 800m heavy at times and ease in the afternoon. Westerly gales force winds will ease to a strong southwest wind on Sunday afternoon. Freezing level dropping to 1200m on Sunday morning and then 900m by afternoon. The snow may be hard above 2000m and lower as the freezing level drops in the morning. You'll need an ice axe and crampons!

Cover above 1800m is reasonably consistent, particularly in the west and south of the park. Snow cover is intermittent below 1800m particularly in the north and east of the park.  13mm of rain below 2000m has saturated the snowpack. This has increasing loose wet avalanche danger. Snow above 2000m may still be wind-transportable due to continued snow flurries above that elevation. Combined with strong winds from the westerly quarter, this continues to promote wind slab danger at upper elevations.
