Travel and Terrain Advice
Heavy snowfall continues, and it is a very dangerous avalanche condition. Behavior within avalanche terrain is not recommended. Pay attention to the triggering of storm slabs on steep slopes. It is a situation where visibility is poor and it is difficult to recognize the surrounding terrain and appearance. Pay attention to the possibility of avalanches from steep slopes overhead, even if you yourself are in a loose slope. Terrain traps such as rocks, deep ravines, and cliffs that increase damage when an avalanche occurs are exposed. It is forecast that the winter-type atmospheric pressure arrangement will continue. The risk of avalanches increases due to weather changes. We encourage you to make prudent decisions.

概要
Avalanche
Yesterday (23rd), there were reports of human-induced observations of multiple planar avalanche sizes 1.5 on the eastern slope near 2400m and multiple spontaneous point avalanche sizes 1.5 on the southeastern slope near 2200m altitude However, visibility is poor and limited observation.
Snowpack
Snowfall due to stormy weather that began on 22nd is over 100cm above the old snow. Yesterday, low density snowfall was observed at the bottom of this snowfall, which was very sensitive to human stimuli. The connection between the recrystallized old snow in the high elevation zone unaffected by rainfall and the new snowfall is unknown.
Weather
The current temperature at 4:40 in Murodo is -9.7 degrees Celsius. Visibility is poor and snowfall accompanied by strong winds continues. The Japan Meteorological Agency forecasts that it will be winter type atmospheric pressure arrangement and the atmospheric condition will be very unstable, so it will be cloudy from the afternoon due to rain at the foot of the mountain, there will be places accompanied by lightning, and snowing in high altitude mountainous areas It's been.
