Avoid avalanche terrain.
Heavy snowfall, strong wind, and a weak layer in the snowpack mean that avalanches are almost certain.
Expect deeper and more reactive slabs in wind affected terrain. Storm snow sits over surface hoar and a crust, rider triggering is almost certain as a result.
Over the past few days numerous storm slab avalanches up to size 2.5 have been observed in the region. These avalanches were triggered naturally, remotely, and by riders on all aspects and elevations.
An additional 50 to 80 cm of storm snow is expected by Friday afternoon. This new snow will be accompanied by strong southerly wind, forming deeper deposits in north and east facing features.
A layer of large surface hoar is found down 30 to 60 cm in sheltered treeline features. Below treeline a crust is found at this interface.
The mid and lower snowpack is well settled with no current layers of concern. Treeline snow depths throughout the region range from 250 cm to 350 cm.
