Travel and Terrain Advice
Heightened avalanche conditions on specific terrain features. Be on the lookout for wind slab formations. Observe the snow surface conditions carefully to spot slabs forming on the terrain. Avoid areas with convex rolls or isolated terrains where the terrain does not support the snowpack, which can easily trigger avalanches. There is still not enough snow in the lower treeline. Be alert for exposed "terrain traps". Keep to the principle of stopping at safe places, moving at reasonable intervals, and so on. This will reduce the number of accidents in case of emergency. Have a good day.

概要
Avalanche
A size 1 avalanche was observed yesterday (January 5) during safety control operations at the ski resort. No new avalanches have been reported in the mountain area.
Snowpack
Weak snowfall is still continuing in the northern part of the mountain range, but today appears to be the end of the stormy weather cycle that began on New Year's Day. At lower elevations, snow is observed to be settling and sintering steadily. On the other hand, at higher elevations, strong northwest to west winds have been blowing every day, so be on the lookout for wind slabs.
Weather
The Japan Meteorological Agency is forecasting westerly winds, later southerly winds, snow or rain, from midday, cloudy, with a high of 5°C (13 m elevation) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is -6°C (as of 4:45 a.m.), with no new snowfall in the past 24 hours.
