Points saillants

Mild temperatures and rain are expected through the weekend. Combined with a poor overnight freeze, this may further weaken the snowpack and increase the avalanche danger at treeline and below during the day.

    Expect the firm melt freeze crust to deteriorate rapidly with the warm rainy conditions which are in the forecast through the weekend. Loose snow avalanches are possible below treeline if we receive heavier than predicted showers.

    Large triggers such as cornice failure or serac fall can trigger very large avalanches. Recently, an ice fall released a large slab avalanche on a steep north facing glacial slope on Mt Andromeda.
