Snowpack

Southwest winds with stronger gusts built shallow (~10cm), fresh windslabs on a northeast aspect at treeline. Observed sensitivity was isolated. The modest new snow amount was well adhered to the old surface in other locations. Windward slopes near treeline were mostly scoured of the new snow by the moderate southwest winds and the 50 mph gusts.
