In sintesi

The chance of human triggering will continue to decrease with a long period of cool weather and little precipitation forecast through next week. Facetting and slow weakening will be the next long term trend for the snowpack.

    Strong winds have been moving snow from the west and north for the past week and hard wind slabs have formed. It is likely that any slab will step down to the weak base. Choose moderate slope angles & low consequence terrain.
