Avalanche Summary
Only sluffing in steep terrain has been reported in the past couple days.
No other new avalanches have been reported since the weekend, but reports have been limited, especially in areas near Terrace. Please consider submitting your observations to the Mountain Information Network.
Snowpack Summary
By the morning of November 28th up to 50 cm could overlie variable snow surfaces, including small facets and/or surface hoar in sheltered areas and heavily wind-affected snow in exposed terrain.
In sheltered terrain in the northern part of the forecast region, a surface hoar layer may be found down around 80 cm.
A crust from early November can be found down 80 to 120 cm. Below this prominent crust are several other crust layers from October.
Snow depths vary across the region, but generally range from 100 to 230 cm in the alpine and about 50 to 100 cm at 1000 m.
