Travel and Terrain Advice
Look for new Windslab that formed yesterday at higher elevations. Use caution around newly formed Cornices as they will be weak and likely to fail easily. Assess changes in the snow condition if the sun comes out today. Watch out for a thin crust on the surface that formed yesterday on steep solar slopes.
Avalanche Problem
ウインドスラブ Wind slab
Recent North and North-West winds have redistributed the storm snow onto leeward slopes.
ストームスラブ Storm slab
Warm temperatures have caused the recent storm snow to settle into a slab. This may still be a problem today on slopes that are warm and sunny.
概要
