    We have very few observations from the alpine, but suspect there may be some thin windslabs in the immediate lee of features.  Watch for reverse windloading on features from the recent East winds.

    There is 20-40 cm of  light density storm snow on the supportive Nov 6 raincrust.  Generally bonding well to the crust now, except in a few select areas where the local wind  has created a slab. See our NEW AVALANCHE OBSERVATION tab for more details!

Weather Forecast

Temperatures will continue to drop tonight to 15C for tomorrow's high and -20C friday night.  Winds should be light Easterly. Expect a few flurries along the divide tonight.  Sunny skies forecasted for Saturday, but still -15C.

Snowpack Summary

Snowpack depths range from 50 cm (Bow Summit) to 80 cm along & west of the divide.  The midpack Nov 6 rain crust is about 5 cm thick with 20-40 cm of llight snow on top..  Except for isolated wind affected features, there is a good bond to this layer.

Avalanche Summary

Only a few isolated hard slabs (40 cm thick) have been found to be reactive to ski cutting on the rain crust on alpine South aspects in the Lake Louise area.  No new avalanches have been observed, but the visibility was poor today.
