Points saillants

Seems most of the snow is falling to the West of us, and there is little to no snow in our forecast. Expect broken skies and warmer temps the next few days.

    Wind events, prior to the cold snap, created hard windslabs in loaded alpine terrain. During the cold snap these slabs were less sensitive, but may still be reactive in some areas now thats its warmer.

    Contrary to what was forecasted, we only received 10-15 cm in the last 24 hr. Moderate SSW winds have developed thin reactive soft slabs in the immediate lees of features. This new snow rests on the weak facet interface from last weeks cold snap.

    There is a weak, faceted base found in most places except the west side of the divide. Many thin, trigger spots exist in the alpine and treeline due to strong winds. Click our Facebook link below to see images of recent basal failures near Sunshine.
