Highlights

Warm temps, little precip and light wind over the next few days is promoting a trend of decreasing hazard. The next storm system is expected late monday with more precip; this will drive the danger rating back up. Cornices are sensitive presently.

    Subsequent to the Jan 4 wind/precip event windslabs are bonding uncharacteristically well to the old surface. These windslabs are between 10 and 25cm deep.

    Human triggering is becoming less likely, however, consequences are high and avalanches will be big if triggered. Today, a lone skier remotely triggered a size in West Bowl, (Lake Louise). See picture @ acmg.ca/mcr
