  Strong winds blowing from the southwest continue to form fresh slabs on leeward slopes. These slabs could be 1 foot deep and easy to trigger in steep terrain. Upside down or slabby snow and cracking around your sled or skis could indicate an unstable slab. Wind slabs at middle elevations will become possible by the end of the day as temperatures decrease, allowing for snowfall instead of rain.

  A new snow avalanche could break into old layers buried earlier this season. An avalanche breaking deeper would be large enough to bury or injure a rider.

  Weak snow formed in November sits at the bottom of the snowpack. While the chance of triggering an avalanche on this layer is unlikely, an avalanche failing within the new snow could put enough weight on the snowpack to break deeper into old snow. Very steep, shallow, rocky areas are most suspect.

  Near and above freezing temperatures are forcing the snowpack to go through rapid change, which can lead to unpredictable avalanche conditions. Cautious route finding and conservative decision making should be used around steep terrain
