Weather Forecast

The ridge of high pressure will, over the next 3 days, flatten and move south. This will allow a strong westerly flow of cold moist air over the region for the weekend. For more details: Avalanche Canada's, Mountain Weather Forecast.

Snowpack Summary

Variable surfaces including temp/rain crust, hard wind press and loose snow sit above the November rain crust which goes as high as 2200m. Total snow pack height in alpine is around 45-85 cm. Wind pressed/scoured features to wind slabs in lee features in the high alpine. Cross loaded gulleys may threaten ice climbs from above.

Avalanche Summary

Previous strong winds transported old snow through the high alpine peaks and ridge tops. Hazard can be expected to increase in isolated areas where wind effect and loading is visible. No natural activity observed or reported in the forecast region.
