    There is a lot of variability in the region. Winds that were strong in the South created some pockets of wind slab. In the North the winds were light and there is a more uniform soft storm slab.

Snowpack Summary

There is a lot of variability in the recent storm snow amounts and the amount of wind effect across the region. The Harvey Pass area has seen a lot of wind. Thin stiff wind slabs have formed, and fetch areas have been stripped. The Crossing Creek area has seen less wind and about 20 cms of new snow. It was snowing all day Friday, so we expect the storm snow to continue to accumulate. The storm snow has not been reported to be reacting as a cohesive slab.
