Lo esencial

With a forecast of fresh snow falling with strong winds, expect to find an increasingly reactive snowpack and avalanche hazard highest at the end of the day.

    This problem is trending towards dormant, especially where a thick supportive crust is found down 20-40 cm (south of Whistler, this supportive crust reaches mountain tops). A heavy input of new snow may test this layer.

Terrain and Travel Advice

  • Avoid shallow snowpack areas, rock outcroppings and steep convex terrain where triggering is most likely.
