      Na Dry Loose up to Sz 1. Some Pinwheeling observed later in the day.

      Na dry loose on steep terrain. 

From the Sea to Sky Advisory: 

Since Wednesday, both natural and human triggered avalanche activity has been mostly limited to small pockets of storm slab and loose dry sluffs confined to isolated features. On Saturday, a size 1.5 natural cornice fall was reported in this MIN from the Garabaldi area.

A widespread natural cycle occurred during the storm Monday night through Tuesday, storm slabs size 2-3 and loose wet size 1-2.


      Lots of hidden hazards right now in the alpine. Ski and board with care.

      If your not sure where to go or what is closed ask a ski patroller.

      Powder covered rain runnels.

    Surface Hoar is growing. Could be interesting with a load on the Dec 9 Melt Freeze Crust, MFcr.

    Snow guns were making a nice surface Saturday am.

      Colder temperatures should make the ski out much nicer.
