Highlights

Up to 15cm snow along the divide and possibly 15cm tonight. Eastern areas have received considerably less. Watch locally for snowfall amounts as this could bump the hazard to high in the alpine. Don't expose yourself to larger, exposed features. SH

    The Valentine surface hoar is down 70-100 cm, and activity on this is slowly subsiding. Many of the large paths have run already, but any feature which hasn't has the potential to cause a large avalanche. We have low confidence in most avy terrain.

    Storm slabs 20-40cm thick formed over the last day are reactive to triggering in steeper areas. The storm will peter out by Friday morning but with additional snowfall and winds tonight, expect these to be reactive in the short term.
