As rain will be turning into snow, total snowfall amounts are uncertain.
Summary
Confidence
Moderate
Avalanche Summary
Evidence of a small loose avalanche from the past weekend may still be visible. The likelihood of avalanches will increase with ongoing strong winds and rain turning into snow on Tuesday night.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Snow is accumulating at higher elevations despite lower elevations being almost snow free
- Closely monitor how the new snow is bonding to the old surface.
