  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.
