Travel and Terrain Advice
Careful action is needed in areas where there was a lot of snowfall until this morning. Even in the forest zone, reduce the slope and be wary of terrain areas such as convex where the terrain is difficult to support snow cover. Even small avalanches can be fatal if they are washed away in areas where there are trees in the outbreak zone or in the runway. The instability is near the surface layer of snow cover, so please check its condition using a safe, small terrain. The snow is in good condition with a sense of gliding. Have a safe day

概要
Avalanche
On the north side of the mountain area where the amount of snowfall increased yesterday (29th), size 1 surface avalanches and point avalanches were observed.
Snowpack
Snow clouds are hanging from the west to the north of the mountain area, and snowfall of 20-30 cm has occurred in the past 12 hours at an altitude of 1,000 m. In the fresh snow of the past few days, there are parts that have not yet been sufficiently increased, and it is in a state of reaction to extreme terrain shapes.
Weather
The Meteorological Agency predicts northwestern winds, initially slightly strong, snow, sometimes cloudy, and a maximum temperature of 3 degrees (elevation 13 m) for the Joetsu region of Niigata prefecture.
