Choose low-consequence terrain
The combination of 40 to 90 cm of storm snow, strong wind, and weak layers means rider triggered avalanches are very likely.
Expect deeper and more reactive slabs in wind affected terrain. Storm snow sits over surface hoar and a crust, rider triggering is likely as a result.
Over the past couple 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.
By Thursday afternoon, 40 to 90 cm of storm snow may have accumulated with the highest amounts on the immediate coast. This new snow overlies surface hoar in sheltered features and wind pressed snow in exposed terrain. Below 1100 m this recent snow overlies a crust.
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.
