Travel and Terrain Advice
Sunny skies and warmer temperatures are in the forecast. As crusts melt during the day, if your feet or skis sink deep or snowballs begin to roll, it is a sign of increased danger. Watch for loose snow avalanches from large southerly steep slopes. Also watch for glide avalanches from collapsing snow cover, open cracks, and cliff-like terrain. Please do not enter the lower part of such slopes or pass through them quickly. In the Nishikurozawa area of Tanigawadake, there is a possibility that a search operation will be conducted for the avalanche that occurred on the 20th. Please cooperate with the instructions of the staff in the vicinity of the avalanche site when search operations are underway.

Beware of large steep slopes that increase the amount of snow involved.
概要
Avalanche
Yesterday, there were reports of multiple glide avalanches (size 2) and numerous loose snow avalanches (size 1-2) on extremely steep southerly slopes.
Snowpack
The recent stormy snowfall is settling and bonding with the lower crust is up. The snow surface is expected to be wet in all directions at least below 1900 m, and thin crusts are expected to have formed during the night. At lower elevations, the effect of elevation is stronger and the strength of the snowpack is weaker. No vulnerability was observed from the middle to lower layers of the snowpack.
Weather
As of 4:00, the temperature at AMeDAS Fujiwara is 0°C. At around 1300 m elevation, the temperature is 7.4°C. There is no cooling during the night. The Japan Meteorological Agency is forecasting clear skies at the foot of the mountains in northern Gunma Prefecture, with occasional cloudiness until late afternoon, and daytime temperatures in Minakami Town rising to 13°C (55°F), as high pressure is expected to prevail, but with the influence of moist air and a pressure trough.
