  The majority of the windslabs are bonding well, but there remains the potential to trigger isolated slabs in steep, wind loaded areas in the alpine. Assess terrain cautiously.

  Large temperature swings from -20 at night to +2 during the day has us in a melt freeze cycle on south aspects. The temperature inversion was less today but still prevalent. Steep south alpine slopes continue to release naturally in the afternoon.

  Solar radiation has led to a re-awakening of two instabilities. Recent wind slabs and the early season basal facet layer. They have produced a few large avalanches on steep unsupported alpine features. Activity was less today yet remains a concern.
