Travel and Terrain Advice
If you want to raise the elevation, check the formation of a windslab on which the old snow rests On slopes affected by solar radiation, it rests on a hard snow surface that tends to be a sliding surface. If you can see the formation of the slab, try to avoid places with convex or isolated shapes that can easily become trigger points, and look for lines with reduced slopes. Also, there are many places where hard snow surfaces are exposed, so be careful about slipping. In places with very low elevations, think about the effects of warming during the day. Snow blocks in extreme terrain are prone to collapse. Don't forget to be vigilant to the top of yourself.

概要
Avalanche
Yesterday (1st), multiple point wet snow surface avalanches of size 1 were observed at low elevations. In addition, collapse of snow blocks has also been reported.
Snowpack
The snow on the surface of the snow cover is settling due to the heat rise and solar radiation in the past few days. The high elevation on the north side is still dry, but on the south side it gets wet in 10 parts, forming a thawing frozen crust. On top of this, snowfall until this morning is listed at a high altitude, but the amount is estimated to be small. However, since there is a very strong western wind blowing in the Alpine, the formation of wind slabs is strongly suspected, and especially caution is required on the southeast side.
Weather
The Japan Meteorological Agency predicts southern winds, daytime, northern winds, cloudy, sunny from the evening, and a maximum temperature of 8°C (elevation 13 m) for the Joetsu region of Niigata prefecture. At Myoko Kanzan (altitude 350 m), the temperature is 3.1℃ (as of 5:00), and there is no new snowfall in the past 24 hours.
