Travel and Terrain Advice
At higher elevations, the snow surface is expected to be hard and frozen. Be careful of slips and falls. At lower elevations, we recommend action before the crust loosens up due to rising temperatures. When the crust thaws and your feet or skis sink deep or snowballs begin to roll, this is a sign of increased danger. Watch for collapsing snow cover, loose snow avalanches from large steep slopes, and glide avalanches from glide cracks or cliff-like slopes. Do not enter the lower part of such areas or pass through them quickly.

概要
Avalanche
Yesterday, there were reports of observing glide avalanches and loose snow avalanches and point-generating wet snow avalanches on extremely steep slopes.
Snowpack
The snow surface is in a cycle of melting during the day and freezing at night to form crusts. At lower elevations, the strength of the snowpack is weak due to weak freezing. Weakness is not observed in the middle to lower layers of the snowpack. The interior of the snowpack is wet due to yesterday's warming, and attention should be paid to the movement of glide avalanches.
Weather
As of 4:00 pm, the temperature at AMeDAS Fujiwara was 0.7°C (32°F) and -3.7°C (-3.7°F) at 3:00 pm at around 1300 m elevation. The Japan Meteorological Agency is forecasting cloudy skies at the foot of the mountains in northern Gunma Prefecture with occasional sunshine after noon, rain and snow showers until morning, and temperatures as high as 8°C in Minakami Town, due to the influence of a pressure trough and moist air.
