    The wind slab problem seems to be most active in Eastern areas where there was more wind effect during the Nov. 18th. wind event.

    We were seeing occasional skiier triggered , and explosive controlled avalanches on the Oct 26 crust at local ski areas. This problem seems to be most reactive in areas where the wind has created more of a slab on top of it.

Weather Forecast

A little snow, a little cold weather. Most of the flow is expected to the south of us.
