Travel and Terrain Advice
Be aware of unstable slabs that remain in certain terrain, where elements such as very steep slopes, isolated shapes, and convexities combine. And also, note the change in slab properties due to diurnal warming. In the below treeline, the gully is not yet fully filled. Watch out for "terrain traps." Have a good day.

概要
Avalanche
No new avalanches were reported yesterday (January 6).
Snowpack
In the treeline and alpine, strong northwest to west winds during the stormy period have shifted the previous snowfall significantly. Older, harder snow surfaces are showing on the ridge where the wind hits, and wind slabs are forming on the downwind side. Yesterday's observations showed limited human stimulus response to wind slab, but caution should still be exercised in areas of easily triggered isolated terrain.
Weather
The Japan Meteorological Agency is forecasting winds from the south, westerly winds during the day, cloudy, rain or snow in the evening, and a maximum temperature of 9°C (13 m elevation) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is -9°C (as of 4:45 a.m.), with no new snowfall in the past 12 hours.
