- Strong winds at all elevations produce wind-affected surfaces even in sheltered areas.
- Strong SW winds with clear weather through 12/21.
- Another large multi-day storm started during the night on 12/21 with a mix of rain and snow. Snow levels fluctuated between 7000 and 8000 ft. Gale force SW winds accompanied the storm.
