Points saillants

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.

    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
