Travel and Terrain Advice
Those who raise the elevation should be wary of unstable windslabs that remain in the terrain. Avoid extreme geometries or terrain that does not support snow cover. On slopes that were strongly affected by yesterday's temperature rise and solar radiation, it is difficult to slide, such as crusts forming. Control your speed and avoid collisions with trees, etc. Please do smart group management while being careful about traps in the terrain. Have a nice weekend
Avalanche Problem

概要
Avalanche
On the south side yesterday (9th), several wet snow point avalanches, size 1, were observed in the afternoon.
Snowpack
The snow in the previous stormy weather is proceeding with sintering. And due to yesterday's rise in temperature and solar radiation, melting of surface snow progressed on the south side of the forest belt, and point occurrence avalanches of snowballs and wet snow were occurring. At higher elevations, westerly winds are continuously blowing, and you need to be wary of windslabs that remain in the terrain.
Weather
The Japan Meteorological Agency predicts southern winds, daytime, northern winds, cloudy, sunny from the afternoon, and a maximum temperature of 6°C (elevation 13m) for the Joetsu region of Niigata prefecture. At Myoko Sasagamine (elevation 1310m), the temperature is -4℃ (as of 5:00), and there is no new snowfall in the past 12 hours.
