Avalanche Forecast
Regions: Banff Yoho Kootenay.
Weather Forecast
For the next few days leading into the weekend, expect seasonal temperatures (-8 to -13) and the occasional snow flurry bringing light amounts of snow. Moderate West to North West winds will add to the chill and may add to the alpine surface windslab issue.
Snowpack Summary
Variable surface wind slabs have been found in immediate lee ridge features, as well as open terrain above 2800m. In sheltered locations, very good skiing can be found from 2500m to as low as 1750m. Lower than that and things get a bit thin . A well-settled mid-pack sits atop the Nov 6 rain crust, which is starting to break down in some locations.
Avalanche Summary
A couple of cornice triggered size 1-1.5 slab avalanches, 20-40 cm thick, in the last 24 hours above the Bourgeau left ice climb (SE asp) near Sunshiine. They ran quite far for their mass, but stopped about 150 m above the climb. No other new avalanches reported today.
