Travel and Terrain Advice
Pay attention to the storm slabs formed by yesterday's snowfall at high altitudes. It is important to look for convex and unsupported terrain that is easy to trigger, and choose routes and gliding lines that are skillfully avoided. On the other hand, where elevations are low, the temperature is forecast to rise today. Be aware of point-generated avalanches due to wet snow during the day on steep, southerly slopes that are heavily affected by solar radiation. In places where there is yesterday's fresh snow, there may be a pattern that occurs due to a decrease in its strength. Wet or wet snow is so heavy that it is easy to scoop underfoot. Think about whether there are any “terrain traps” below the terrain you are currently trying to act on. Have a nice day

概要
Avalanche
There are no observation reports of the new avalanche yesterday (22nd).
Snowpack
From the vicinity of the forest limit to the top, there seems to have been some snowfall accompanied by north winds during the day yesterday (22nd). At high altitudes, the wind has now subsided, but it cools well under the influence of cold, so it is necessary to pay attention to the behavior of the slabs formed by yesterday's snowfall.
Weather
The Japan Meteorological Agency predicts southern winds, daytime, north winds, sunny, cloudy, and high temperatures of 11 degrees Celsius (elevation 13 m) for the Joetsu region of Niigata prefecture. At Myoko Sasagamine (elevation 1,310m), the temperature was -10℃ (as of 5:00), and there was 7 cm snowfall in the past 24 hours.
