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 (size 1) and loose snow avalanches (size 1) on extremely steep slopes.
Snowpack
The snow surface is in a cycle of melting during the day and freezing at night to form crusts. Last night, at least below 1500m, rainfall is expected to have had a strong influence, and the strength of the snowpack is weak. Weakness in the middle to lower layers of the snowpack has not been observed.
Weather
As of 5:00, the temperature at AMeDAS Fujiwara was 1.4°C with 5.5 mm of rainfall during the night. At around 1300 m elevation, the temperature was 5.3°C. There is no cooling during the night. The Japan Meteorological Agency is forecasting clear skies and cloudy skies with daytime temperatures rising to 20°C in Minakami Town due to the high pressure but cold and moist air above.
