Alpine Fair There has been reports of windslab avalanches in alpine terrain. The snowpack has had little time to settle and will need more time to become more stable and hazard will increase with more wind and snow.
Treeline Fair Windslab avalanches have also been reported at tree-line. This may start to settle today, but beware of more loading from increase in wind and snow.
Below Treeline Fair Steep sheltered slopes below tree-line will have hazard of loose dry avalanches.
信頼度：○ good □ Fair △ Low
Travel and Terrain Advice
Trail breaking and travel in the back country will be deep and can be slow so plan ahead your route and time to avoid and reduce exposure to hazards. Advised to meet new terrain with caution and scouting especially creek exits as they are slowly becoming filled in.
