Snowpack Summary

Wind slabs are found on the surface in wind-prone alpine terrain, and below the surface in lee and cross-loaded terrain features. A few slab avalanches (both human and naturally triggered) in steeper terrain have been noted in recent days. The basal layers of the snowpack are typical of the eastern Rockies for this time of year, and consist almost entirely of facets. Unfortunately this condition is not going anywhere fast, and may be with us for the season.

Weather Summary

Monday evening could see about 4cm of snow with -18 as the overnight low. Tuesday will be cloudy with sunny periods, High of -16 and 30km/h winds out of the West.

More details can be found in the Mountain Weather Forecast.
