Signs of Unstable Snow

Observations

Light / moderate snow throughout the day and sustained moderate winds with strong gusts. New snow was wet. Did not observe any windslab formation in the morning but conditions intensified and the afternoon and exposed north facing slopes began to exhibit signs of windslab.
