Highlights

While the likelihood of skier triggering is relatively low we have observed several large, high consequence avalanches on steep unsupported alpine slopes. Don't let the sunny skies cloud your judgement.

    The majority of the previous windslabs are bonding well, but there is still the potential to trigger isolated slabs in steep, wind loaded areas in the alpine.

    Large temperature swings from -28 at night to plus 2 during the day has put us in an early melt freeze cycle on south aspect slopes. There has also been a significant temperature inversion. Ice climbers pay particular attention to these patterns.

  • Deep Persistent Slabs

    • Alpine

    Warm temperatures and solar radiation have lead to the re-awakening of two instabilities. Recent wind slabs and the early season basal facet layer have produced a few large, high consequence avalanches on steep unsupported alpine features.
