    Heavy accumulations will heighten the avalanche danger in the alpine and gulley features at lower elevations. Soft storm slab development with the november rain crust as a failure plane on wind loaded terrain. Loose snow sluffing from steep terrain.

Weather Forecast

A low pressure frontal is moving over the Rockies Wednesday evening with expected snowfall of up to 50cm over the next 36hrs. Alpine winds will be moderate to strong from the south and west.

Snowpack Summary

Variable snowpack conditions in the alpine with up to 40cm in wind loaded areas on N - NE aspects. One or more rain crust  close to the ground up to 2,500m with weak faceted snow above and below. Recent storm snow is being transported near ridge tops. Early season conditions at all elevations. 

Avalanche Summary

Loose to size 2 in the alpine. Isolated soft slabs at upper elevations can be expected. No new field observations
