Travel and Terrain Advice
The spring cycle has begun. Avalanche danger levels vary widely from "low" to "high" during the course of a day, depending on daytime temperatures and the effects of solar radiation. We recommend that you take action before the crust loosens up due to the effects of solar radiation and warmer temperatures. When the crust melts 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 multiple glide avalanches and loose snow avalanches on extremely steep slopes and point-generating wet avalanches observed.
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 from the middle to the lower layers of the snowpack.
Weather
As of 4:00 p.m., the temperature at AMeDAS Fujiwara was 2.6°C and 8.6°C at around 1,300 m elevation, with no nighttime cooling. The Japan Meteorological Agency is forecasting clear and sometimes cloudy skies in the foothills of northern Gunma Prefecture, with daytime temperatures rising to 13°C in Minakami Town, as the area is expected to be covered by high pressure but affected by a pressure trough, moist air, and cold air.
