Points saillants

If the forecasted storm arrives, the danger will rise, increasing the potential for large avalanches to occur on the Valentine's layer. See our Facebook page for a picture of a recent avalanche that occured on this layer on Mt. Rundle.

    10-20 cm of snow along with strong W winds are forecasted for Tuesday. Smaller avalanches initiated with this new snow have the potential to step down to the Valentines layer, which would result in large, destructive avalanches.

    Down 70-150cm, the Valentines surface hoar is producing harder shears; however, a remotely triggered size 2.5 avalanche today on an E aspect near Healy Pass shows that it is still possible for a skier to trigger this layer.
