Forecast strong south winds on Thursday may form reactive wind slabs on lee features. 15 to 20 cm of recent snow overlies heavily wind-affected surfaces in open areas at all elevations. Up to 60 cm of snow can be found in sheltered areas.

Two persistent weak layers of either crust/facets or surface hoar may be found in the top 100 cm of the snowpack. No recent avalanches have been reported on these layers.

Facets or depth hoar exist at the base of the snowpack, especially in the inland areas that have a shallower snowpack.
