Travel and Terrain Advice
Snowfall has begun in the northern part of the Myoko mountain range. The forecasted snowfall is not heavy, but watch out for storm slabs in areas with more accumulation of fresh snow due to the strong westerly winds. Yesterday, it appears that the snow surface was wet at all elevations, so check the bonding of this snow surface with the new snow. Meanwhile, at very low elevations, positive temperatures continue, as well as weak precipitation. The danger of glide avalanches continues, so stay away from slopes with glide cracks.

概要
Avalanche
Yesterday (5th), several size 1-2 glide avalanches were observed in the morning. Numerous snowballs were also observed during the day.
Snowpack
High temperatures and light precipitation yesterday left previously new snow wet. The inflow of cold air due to the winter pressure pattern began yesterday evening and temperatures are dropping. Weak snowfall has also begun this morning in the northern part of the Myoko mountain range. At very low elevations, positive temperatures have continued since yesterday, and we continue to need to watch for glide avalanches.
