Around 10 to 20 cm of new snow accumulated with strong southerly wind. The storm formed wind slabs in lee terrain features at higher elevations. The precipitation fell as rain below 1100 m.
The remainder of the snowpack is strong.
There is insufficient snow to form avalanches for most below treeline elevations.

- If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
