Avalanche Summary
A natural avalanche cycle occurred a few days ago as rain and warm temperatures infiltrated the region. Slab avalanches up to size 3 were observed in the Smithers and Seaton areas.
If you head to the backcountry please consider submitting your observations to the Mountain Information Network.
Snowpack Summary
New snow accumulates atop a crust or moist snow from rain in the past few days. Strong winds will create heavily wind-affected surfaces and redistribute new snow into fresh wind slabs.
We suspect two surface hoar layers in the mid-snowpack have been cleaned out by the rain.
Deeper in the snowpack, a rain crust from early November seems to be bonding well to the surrounding snow.
